the MG corners better/faster than the Lancer did. I guess that's due to
the short wheel base and wider tyres.

In part. Suspension kinematics play a greater role these days. Your
current MG has a torsion beam rear suspension, a type that could not be
designed before the advent of computer modelling. IIRC, your MG3 was the
same. As I have stated in the past, they are a compromise in handling
and ride but the coils are easy to *tune* and the kinematics of the
trailing arms are simple but effective. They are not new. Fiat has used
the torsion beam rear since the early 80s on the Uno since it gives a
good *space* configuration in compact wagons, hatches and SUVs but still
provide good handling. For instance, Peugeot 308 uses the torsion beam
for its handling characteristics. Even the moose test wasn't a problem;



Handling has come a long way.

That's all the MG ZS was ever meant to be. Ditto with the MG3. Both are
cheap runabouts and I don't think there's anything wrong with that.
These days my needs are for a cheap runabout - but I'll stick with
Toyota if possible.

**Indeed. Back in the early 1980s, I took a mate's Porsche 911T (2.7L)
for a spin. It was, by a considerable margin, the most exciting,
engaging car I had ever driven. Quick, precise and great handling. A
couple of years ago, another mate called in with his classic Porsche
911T (2.7L). He took me for a spin. What a POS. Slow, average handling
and big disappointment. Same car. 40 years difference. And torsion bar
rear suspension. My 23 year old Stagea kills the old Porsche in every
department. Except for styling. Oh, and NEVER drive an old Porsche in
the wet. You know why. In my Stagea (AWD), I don't even notice wet roads.

Trevor, take what this moron claims with a grain of salt the size of
Nebraska, as he has absolutely *no* idea what he's talking about. Like
his utter nonsense here about torsion beam rear suspensions not being
possible before the advent of computer modelling.

This claim is utterly *ridiculous* :)

Torsion beam suspension has been around since the 1920's. The world's
most popular car, the VW Beetle, first appeared in 1936 and used it for
decades. Even the Porsche that you talk about so fondly for it's great
handling characteristics used torsion bar rear suspension and did so
going back to the very first days of the 356 :)

The bloke has no fucking idea and just makes this shit up as he goes
along. He is the Donald Trump of aus.cars, and why you people keep
giving him the attention he craves his a mystery as all he ever does is
insults your intelligence :)

Oh dear Darren, it appears you have made a fool of yourself - again! Or
is that *still*!

For your edification, I was referring to a torsion *beam* suspension,
not a transverse torsion *bar* suspension. FFS, Valiants had
longitudinal torsion bar suspensions, as did the venerable Morris
Marina. They were *not* torsion beam suspensions - which are an entirely
different kettle of fish.

The VW and Porsche you refer to - they are pure torsion bar. That the
torsion bar is *housed* in a solid beam does not make that *beam* a
*torsion beam*. It's the torsion bar that *flexes*, not the beam. In
Felix' MG, the suspension has *no torsion bars* at all, the car being
suspended upon *coil springs*. In the MG, his current and his previous,
the torsion *beam* is the connecting beam between the two trailing arms.

Nope! From this book;

Car Suspension At Work.
The theory and practice of steering, handling and roadholding
Jeffrey Daniels

A major development of the 1970s, initiated by Volkswagen
but widely copied, is the torsion-beam axle. When the Golf
first appeared, it was equipped with a trailing-arm rear
suspension in which the arms were joined by a semi-rigid
transverse beam. It quickly transpired - to judge by the
evidence of its widespread copying - that this was a
brilliant notion. In particular, it combined two of the
better features of the trailing arm and the dead axle: the
forced camber change of the former, but the higher roll
centre of the latter. It thus incorporated both of the
features which reduced basic understeer.
The system also had structural advantages (it was devised
by Volkswagen in the first place as part of the
outstandingly successful weight control programme for the
Golf). The torsion beam absorbed some of the stresses
which would have had to be fed into the body with pure
trailing arms; it also acted as the rear anti-roll bar,
adding yet another understeer-reducing element. As the
system has been progressively developed, different
manufacturers have used torsion beams of different
cross-section, and mounted them at different points
along the trailing arms so that the rear suspension
member resembles a flat 'H'. Some engineers indeed refer
to the layout as the 'H-beam'. It is clear that the
tuning and positioning of the torsion beam are critical
to suspension performance, and especially to the car's
behaviour in the mid-corner lift-off situation. The Golf
and Polo are noteworthy for their evident positive
rear-wheel camber during cornering, and for their
willingness to lift the inside rear wheel, yet they do
not appear to oversteer violently, even in the most
extreme situations.

Yes, I am in possession of the above book. Not being able to find the
above on-line, I had to type out all the text so excuse any induced errors.

The torsion beam of a Golf is *not* a tube or square shape, that
wouldn't twist at all. Instead, the typical torsion beam is a U shape.

https://www.ebay.com.au/itm/145953436916

Note the U shaped beam in the above linked pic. It was the shape that
required the computer modelling. How to get a beam to flex sufficiently
without fatigue failing - that was the tricky bit. The computers doing
the modelling were quite large. In the early 80s I saw a Camira
undergoing suspension modelling and suspension destruction testing at
the Holden Development Labs at Fishermans Bend. In this case the
engineers were modelling how the suspension deflections were being
transmitted to and through the body - amazing stuff.



Remember how Felix complained that his MG3 rode harsh around town? Well,
that's one of the downsides of a torsion beam suspension - but they do
smooth out nicely at highway speeds however.

Ah Darren, you've done it again! You've *proven* that you have never sat
your arse in an apprentice class in any TAFE college ever, not as an
AME, not as an auto machinist, and definitely not not as a motor
mechanic. In your desperation to win a point, you're making a habit of
this, I have to say. The Golf came out in *1974* Darren and it was the
*first* with a torsion beam. Had you been a motor mechanic apprentice in
the 80s Darren, or the 90s, you would have learnt all about car
steering, suspension and handling - but you didn't get an apprenticeship
because you didn't qualify - failed that year 9 exam, remember? The
Apprenticeship Commission of the day figured that if you couldn't even
pass year 9 English, maths and science, you would be unlikely to be able
to complete, and pass, the TAFE component of the apprenticeship. You're
proving them right! Well done. Now go back and hide in your cubbyhole,
you're insulting everyone's intelligence!

steering, suspension and handling - but you didn't get an
apprenticeship because you didn't qualify - failed that year 9 exam,
remember? The Apprenticeship Commission of the day figured that if you
couldn't even pass year 9 English, maths and science, you would be
unlikely to be able to complete, and pass, the TAFE component of the
apprenticeship. You're proving them right! Well done. Now go back and
hide in your cubbyhole, you're insulting everyone's intelligence!

the MG corners better/faster than the Lancer did. I guess that's due
to the short wheel base and wider tyres.
In part. Suspension kinematics play a greater role these days. Your
current MG has a torsion beam rear suspension, a type that could not
be designed before the advent of computer modelling. IIRC, your MG3
was the same. As I have stated in the past, they are a compromise in
handling and ride but the coils are easy to *tune* and the kinematics
of the trailing arms are simple but effective. They are not new. Fiat
has used the torsion beam rear since the early 80s on the Uno since it
gives a good *space* configuration in compact wagons, hatches and SUVs
but still provide good handling. For instance, Peugeot 308 uses the
torsion beam for its handling characteristics. Even the moose test
wasn't a problem;

Handling has come a long way.
**Indeed. Back in the early 1980s, I took a mate's Porsche 911T (2.7L)
for a spin. It was, by a considerable margin, the most exciting,
engaging car I had ever driven. Quick, precise and great handling. A
couple of years ago, another mate called in with his classic Porsche
911T (2.7L). He took me for a spin. What a POS. Slow, average handling
and big disappointment. Same car. 40 years difference. And torsion bar
rear suspension. My 23 year old Stagea kills the old Porsche in every
department. Except for styling. Oh, and NEVER drive an old Porsche in
the wet. You know why. In my Stagea (AWD), I don't even notice wet roads.
Older Porsches got a reputation as widow makers, hanging on like glue
through corners until suddenly they didn't. A fellow Australian expat
told me that his teenage son, who had just got his licence, had his eye
on an old 911, my advice was, if he was attached to the boy, don't allow
it, if he wasn't, just make sure that he was well insured

I've heard it said that WRX's suffer badly from understeer at their

driving like a psycho on a public road for it to happen, much the same
with the old Porsche.

Rear engined Porsche's are a little bit different. Particularly the 911.

Their problem isn't that they're not a great handling car as they are.
However they're unique compared to most performance cars in that they
give little to no warning when they're at their limit and let go very
quickly once they are. Very few drivers catch it :)

I think it depends a lot on the model. Some of the higher horsepower
variants are pretty easy to unstick. Especially when traction is
anything less than ideal.

Pooor Deryl. So very desperate for someone to talk to that he lets all
these highly dubious Fraudster Facts go unchallenged. Gorn Deryl! Ask
Fraudster for some specific details of *any* experience driving Porches
that he has. And lets not forget here that he's had no connection with
the motor trade for *at least* the last 20+ years. I'd confidently opine
that his only experience would be parking his arse on the back porch.

Actually, it looks more like Daryl is *running interference*, ie.
providing a distraction from the huge cockup Darren made of his (lack
of) *knowledge* of torsion beam suspensions. What was even more humorous
has been Darren's exposure of, by his own words, his lack of knowledge
of *torsion bar* suspension systems. He even attempted to take the focus
off that by pointing to my claim - that the torsion beam suspension
wasn't possible without computer modelling - calling it bullshit.
Numerous engineering texts prove him wrong on that score too - including
the one from which I cited relevant excerpts. These are two sad little men!

FFS Darren, that applies equally well to a Front Engine RWD car with a
bit of power. In fact, it's *easier* since the weight is at the front
and not enhancing traction at the rear. As I said in another post, drive
torque increases slip angles and that is why a powerful 911 will hang
the arse out when the throttle is planted - same as any powerful FE-RWD car.

Been there done that and not had a problem but then I knew not to drive
it like a loonie in the wet.
I had a 1979 911 SC for a couple of weeks, the owner left it with me to
fix a few things and I was given permission to drive it as much as I
liked, fabulous car and I'd have one in a heartbeat, trouble is they are
stupidly expensive, the one I had was bought for about $60k about 8yrs
ago, now its worth around double.
I was talking to the owner of a fully restored 1969 911 at a car show
and I asked how much his car was worth, he told me that he had just
knocked back an offer of $280k, said that the offer wasn't even close.

I've heard it said that WRX's suffer badly from understeer at their
limit but I've never even got close to that limit because you need to
be driving like a psycho on a public road for it to happen, much the
same with the old Porsche.
**Nope. You should drive an OLD 911 on a wet road sometime. You'll
understand.
Been there done that and not had a problem but then I knew not to drive
it like a loonie in the wet.
I had a 1979 911 SC for a couple of weeks, the owner left it with me to
fix a few things and I was given permission to drive it as much as I
liked, fabulous car and I'd have one in a heartbeat, trouble is they are
stupidly expensive, the one I had was bought for about $60k about 8yrs
ago, now its worth around double.
Not sure how price is relevant to the discussion and there is no way you
really drove that car like you owned it so...
Post by Daryl
I was talking to the owner of a fully restored 1969 911 at a car show
and I asked how much his car was worth, he told me that he had just
knocked back an offer of $280k, said that the offer wasn't even close.
...at a car show. What it's worth is dependent on what the next
speculative investor thinks it's worth. What it's really worth is far
less and you only find that out when the bubble bursts.

To a novice driver - they give little warning. To a professional, they
give heaps. What most novice drivers can't handle is the power at the
rear wheels which increases the slip angles at the rear tyre contact
points. If you understood the concept of slip angles and the
relationship with applied torque at the wheels, you might have a clue.
You might also realise that it is the tyres that limit the drivers feel
of the slip angles and that is what provides warning of a rear end

As far as tyres go there are a *hell* of a lot of variables that affect

All factors affecting slip angles. Throw into that mix acceleration,
braking, steering geometry, tyre type, etc. and you'd be getting
somewhere. As it is, you don't even know what slip angles are. Cornering
power Darren, which is defined as cornering force divided by the slip
angle required to generate the force. Involves maths and physics at a
level way beyond the ken of your failed year 9.

But start here anyway;

the MG corners better/faster than the Lancer did. I guess that's due
to the short wheel base and wider tyres.
In part. Suspension kinematics play a greater role these days. Your
current MG has a torsion beam rear suspension, a type that could not
be designed before the advent of computer modelling. IIRC, your MG3
was the same. As I have stated in the past, they are a compromise in
handling and ride but the coils are easy to *tune* and the kinematics
of the trailing arms are simple but effective. They are not new. Fiat
has used the torsion beam rear since the early 80s on the Uno since
it gives a good *space* configuration in compact wagons, hatches and
SUVs but still provide good handling. For instance, Peugeot 308 uses
the torsion beam for its handling characteristics. Even the moose
test wasn't a problem;
http://youtu.be/jMzaufUquys
Handling has come a long way.

That's pretty much it. The Porsche 911, by default, is an understeerer.
All cars are designed thus. What changes that equation is the *power*
delivered to the rear wheels which *changes* (increases) the slip angles
and that results in an effective *power oversteer*. Plenty of video
clips on youtube showing hoons losing control once they've booted their
cars. They boot it, start losing control, then lose their shit and back
right off, and worsen the situation.

Lift off oversteer was a problem that affected many cars, but it wasn't
the 911's biggest problem. The 911's biggest problem was weight bias. On
the early cars it was appallingly bad towards the rear, which made them
great for acceleration traction, but terrible for high speed cornering.
Having a big chuck of weight behind the rear axle meant that the rear
tyres got *very* heavily loaded on turns, and when they reached their
limit the back came around *very* quickly and was almost always
unrecoverable.

It was a consequence of their design, being based on one of the worst
handling cars ever made, the Volkswagen Beetle, and it's precisely why
Porsche wanted to drop the overhanging rear engine for decades.The only
reason they didn't was because the fans revolted.

Later model Boxsters and Caymans got more powerful engines so they are
pretty much as quick as a 911 at a lower price, they also handle much
better than a 911.
The sales figures I found shows 911's outselling Boxster/Cayman about 2
to 1 but Cayenne SUV sales are approx double the other models combined.

Older Porsches got a reputation as widow makers, hanging on like
glue through corners until suddenly they didn't. A fellow Australian
expat told me that his teenage son, who had just got his licence,
had his eye on an old 911, my advice was, if he was attached to the
boy, don't allow it, if he wasn't, just make sure that he was well
insured
Lift of oversteer is a well known characteristic of older Porsches,
anyone who has half a brain should know about that well before they
got behind the wheel, when driven with that in mind not much of a
similar vintage will keep up.
Lift off oversteer was a problem that affected many cars, but it
wasn't the 911's biggest problem. The 911's biggest problem was weight
bias. On the early cars it was appallingly bad towards the rear, which
made them great for acceleration traction, but terrible for high speed
cornering. Having a big chuck of weight behind the rear axle meant
that the rear tyres got *very* heavily loaded on turns, and when they
reached their limit the back came around *very* quickly and was almost
always unrecoverable.
It was a consequence of their design, being based on one of the worst
handling cars ever made, the Volkswagen Beetle, and it's precisely why
Porsche wanted to drop the overhanging rear engine for decades.The
only reason they didn't was because the fans revolted.
At least they started making mid engined cars as well as 911's.
They did.

I always hated the driving position in the 911. Particularly the earlier
models. The pedals felt wrong, the steering wheel came out of the dash
at a funny angle, and the steering feel itself was odd. They got better
as they got newer, but to me the early ones always felt like a kit car.

In the days before phones with built in cameras I hardly ever took any

hardly ever used it other than to take photos of the WWII Jeep I was
restoring at the time, which was the reason I bought the thing in the
first place. I was never really much into photography and never really
cared for photos, but wanted to photo document that car as it was kind
of "historic". For me, anyway.

Since the advent of phones with high class cameras built in I take
*hundreds* of pictures of virtually everything I do, and 99 times out of
100 it's to help me remember how shit goes back together or how I
performed some particular task so I remember how to go about doing it

Last photo I took was a week or so ago and it was of the rotor button
position on one of Les's race cars so I could put it back in exactly the

Had to remove the engine to get the gearbox out to replace all the
syncros, finished it yesterday and the box now shifts perfectly:-)
Photo before that was of Hilux gearbox selectors from the box I was
replacing 3rd gear syncos on.
Thank fuck for youtube and Google, when I was putting the Hilux box back

found a good video and was then able to work out where it went:-)

Phones are *great* for that. Especially as you get older and are less

Yeah, some of the vids can be a life saver. Some are just amusement value :)

My kid's school has a metal working shop where they teach kids basic
machining operations on lathes and mills, and one of the teachers has
asked me to put photos up of some of the stuff I do on a publicly
accessible picture hosting site so they can be used for educational
purposes. It's not just me. They do it with a few locals. A couple of
engineering companies with bigger projects, and a couple of privateers.
They get to look at a wide variety of projects and see things being done
from a few different perspectives. It's educational and I don't have a
problem with it, but I find myself taking a *lot* of photos as a result.

The last one was only a few days ago which was repairing a broken cast
iron crank pulley using tig welded Silicone Bronze which was a first for
me. It turned out well and I'm pretty happy with it, and I'll upload the
photos in a day or two and hopefully the kids will get some benefit out
of it as well.

Sounds like fun, so many different welding techniques available now.
I've never been much of a welder so I'm amazed with what some people can
weld.
Les and I recently helped out a bloke who had crashed his Lotus 7 race
car, we pulled it apart to see what needs replacing or repairing, one of
the things that broke was the RHF suspension upright which is cast
aluminum, it snapped just above the bottom ball joint.
Its a fairly rare part so he's been asking around about it and several
people have suggested welding it, the owner doesn't like the idea and
neither do I but one of the people who suggested welding has apparently
done it successfully before.
Does welding an upright sound feasible to you?
I'd be too scared of it breaking at high speed on the track?
Is it possible that the weld could be stronger than the OE casting?

Welding cast aluminium will give you problems. Welding *any* suspension
parts is a really bad idea.
Post by Daryl

The term you use is confusing. To me it sounds like you are talking
about the *steering knuckle*. (What did you learn in your
apprenticeship? Not much I'll wager!) Anyway, welding a steering knuckle
is *never a good idea*. Ditto for control arms and steering arms.
Post by Daryl

I was hoping you would be too wise to do something as stupid as welding
up a steering knuckle in the first place. More so on a *track car*!

Short answer - no. It will be weaker. The reason is simple - the
steering knuckle and upper and lower control arms are not usually *cast*
alloy. Instead they are *forged* and, as such, they will have a much
improved grain structure in the metal which will also be finer than
anything done by casting. That grain structure also gives the component
a lot of its strength. If the part is broken, you can make two
assumptions - the component was *overstressed* and/or it was subjected
to fatigue failure. It happens to suspension parts you know! All that
stress, all that bouncing up and down, not good for longevity! What
caused it to break before - stress, fatigue - will still be present and
you will, by welding it, create a weaker component by screwing up the
grain structure and the temper of the part. What's more, suspension
components are *heat treated *at the factory*. You weld anywhere and you
will totally screw up any factory heat treatment - and that even applies
to forged steel components.
On that score, think of *forged steel steering arms*. You are not
supposed to heat them at all. If you need to bend a steering arm at all
in order to straighten it, it has to be done *cold* and there's a *hard
limit* on the number of degrees it can be bent. Yes, I know, people heat
and bend these steering arms at times, I get that, but it won't be
happening on any car I'm driving or fixing. Just think what is likely to
happen when a steering arm snaps off at high speed. I guarantee you
won't be casually rolling to a stop! Now think what would happen if the
steering knuckle breaks at high speed.

Since the advent of phones with high class cameras built in I take
*hundreds* of pictures of virtually everything I do, and 99 times
out of 100 it's to help me remember how shit goes back together or
how I performed some particular task so I remember how to go about
doing it next time :)
Last photo I took was a week or so ago and it was of the rotor
button position on one of Les's race cars so I could put it back in
exactly the same place after removing the distributor.
Phones are *great* for that. Especially as you get older and are
less likely to remember everything in exact detail. More so when
there is a considerable length of time between the dismantling and
reassembly as is often the case with me.

Had to remove the engine to get the gearbox out to replace all the
syncros, finished it yesterday and the box now shifts perfectly:-)
Nice :)
Post by Daryl
Photo before that was of Hilux gearbox selectors from the box I was
replacing 3rd gear syncos on.
Thank fuck for youtube and Google, when I was putting the Hilux box
back together I had one small pin leftover that I couldn't find a
spot for, found a good video and was then able to work out where it
went:-)
Yeah, some of the vids can be a life saver. Some are just amusement value :)
My kid's school has a metal working shop where they teach kids basic
machining operations on lathes and mills, and one of the teachers
has asked me to put photos up of some of the stuff I do on a
publicly accessible picture hosting site so they can be used for
educational purposes. It's not just me. They do it with a few
locals. A couple of engineering companies with bigger projects, and
a couple of privateers. They get to look at a wide variety of
projects and see things being done from a few different
perspectives. It's educational and I don't have a problem with it,
but I find myself taking a *lot* of photos as a result.
The last one was only a few days ago which was repairing a broken
cast iron crank pulley using tig welded Silicone Bronze which was a
first for me. It turned out well and I'm pretty happy with it, and
I'll upload the photos in a day or two and hopefully the kids will
get some benefit out of it as well.
Sounds like fun, so many different welding techniques available now.
I've never been much of a welder so I'm amazed with what some people
can weld.
Les and I recently helped out a bloke who had crashed his Lotus 7
race car, we pulled it apart to see what needs replacing or
repairing, one of the things that broke was the RHF suspension
upright which is cast aluminum, it snapped just above the bottom ball
joint.
Its a fairly rare part so he's been asking around about it and
several people have suggested welding it, the owner doesn't like the
idea and
Smart man! Don't let Darren near it either.

neither do I but one of the people who suggested welding has

Welding cast aluminium will give you problems. Welding *any*
suspension parts is a really bad idea.
even I know that

Post by Daryl
Does welding an upright sound feasible to you?
The term you use is confusing. To me it sounds like you are talking
about the *steering knuckle*. (What did you learn in your
apprenticeship? Not much I'll wager!) Anyway, welding a steering
knuckle is *never a good idea*. Ditto for control arms and steering arms.
Post by Daryl
I'd be too scared of it breaking at high speed on the track?
I was hoping you would be too wise to do something as stupid as
welding up a steering knuckle in the first place. More so on a *track
car*!
Post by Daryl
Is it possible that the weld could be stronger than the OE casting?
Short answer - no. It will be weaker. The reason is simple - the
steering knuckle and upper and lower control arms are not usually
*cast* alloy. Instead they are *forged* and, as such, they will have a
much improved grain structure in the metal which will also be finer
than anything done by casting. That grain structure also gives the
component a lot of its strength.
it's the same with golf iron heads. forged irons can to bent to change
loft and lie angles. cast heads can sometimes be bent a little,
depending on the design, but it's very risky as they break easily, as I
discovered many years ago.

Mizuno make the finest forged iron head ..

It's something I'd need to look at before making a call. It could be. It
would depend a hell of a lot on the composition of the component.
Post by Daryl

Is it possible that the weld could be stronger than the OE casting?
I'm not sure about it being stronger, but it could possibly be as strong
as an original part. It would all depend on whether the part was a
casting or a forging.

Cast alloy is reasonably strong, but it can be a complete pig to weld
well because of the typically horrendous make up of the material itself.
Apart from Aluminium, you get other materials in the mix such as tin,
iron, copper, Silicone, magnesium and zinc, which all exist as alloying
elements. They do their job in melding it all together to allow the part
to be cast and machined, but the material is quite "dirty" from a
welder's standpoint making it quite difficult to get a good, solid weld.

Forgings on the other hand are quite different. Forged alloy components
tend to be fairly pure which makes weld integrity a lot easier to
achieve. I would suspect that as cast alloy can be quite brittle and
doesn't like a lot of shock loading that the part is most likely a
forging, in which case the success rate of a weld repair is
significantly greater. As to how effective that repair would ultimately
be would depend entirely on the person doing the repair :)

Would I do it? Short answer is "dunno".

I'd need to look at it and see where it's broken, if it could be pinned
to support the weld or if it's installed state would allow for any
reinforcement laid over the top as a "backup". They're a fairly light
car and used on a smooth track I would think the loads would be mostly
in the vertical and not outrageous, so there's a reasonable chance that
it could be repaired provided it's not completely mangled.

If it were my car I'd probably look long and hard for a replacement
first though :)

For sure he never studied steering and suspensions at TAFE during any
apprenticeship ever. The absolute epitome of a little knowledge being a
dangerous thing. Anyone who says this of a steering knuckle; "They're a
fairly light car and used on a smooth track I would think the loads
would be mostly in the vertical and not outrageous" simply has no idea
of the loads generated at the steering knuckle. The lower ball joint is,
typically, the load carrying joint so, yes, it will carry vertical
compression or tension loads but it will be subjected to extreme side
thrusts during any cornering - and race cars do extreme cornering on
*the track*. What's more, the axle axis is biased towards the lower ball
joint;
Loading Image...

The upper joint is a friction joint, non load carrying, and is purely
for location of the upper end of the knuckle. It will have some side
thrust loads but nothing like that experienced by the lower ball joint.

Here's a good schematic of a typical steering knuckle;

Loading Image...

Note how the axle is biased to the lower joint. That lower joint has the
force of the spring applied to it whereas the top joint is free floating
- purely for location. Look at the pic and just imagine where the forces
are being applied when cornering at high speed *on the track*. The
steering knuckle in question broke right near the ball joint - exactly
wher I would expect it to - given the forces acting upon it.

allow the part to be cast and machined, but the material is quite
"dirty" from a welder's standpoint making it quite difficult to get a
good, solid weld.
Forgings on the other hand are quite different. Forged alloy
components tend to be fairly pure which makes weld integrity a lot
easier to achieve. I would suspect that as cast alloy can be quite
brittle and doesn't like a lot of shock loading that the part is most
likely a forging, in which case the success rate of a weld repair is
significantly greater. As to how effective that repair would
ultimately be would depend entirely on the person doing the repair :)
Would I do it? Short answer is "dunno".
You probably find it would be *unethical* if not downright illegal.

I'd need to look at it and see where it's broken, if it could be
pinned to support the weld or if it's installed state would allow for
any reinforcement laid over the top as a "backup". They're a fairly
light car and used on a smooth track I would think the loads would be
mostly in the vertical and not outrageous, so there's a reasonable
chance that it could be repaired provided it's not completely mangled.
What? Loads *mostly in the vertical*? WTF are you smoking? It's a
*steering knuckle* and, as such, it has loadings every which way!
Think about the loadings when *cornering*! The fact it snapped right
above the lower ball joint should be *more than enough* to indicate
that the knuckle is subjected to severe lateral loadings.
LOL! noddy proves (again) why as an automotive repairer he should be
avoided like the plague.
LOL like flies to a honey pot.

The last one was only a few days ago which was repairing a broken
cast iron crank pulley using tig welded Silicone Bronze which was
a first for me. It turned out well and I'm pretty happy with it,
and I'll upload the photos in a day or two and hopefully the kids
will get some benefit out of it as well.
Sounds like fun, so many different welding techniques available now.
I've never been much of a welder so I'm amazed with what some
people can weld.
Les and I recently helped out a bloke who had crashed his Lotus 7
race car, we pulled it apart to see what needs replacing or
repairing, one of the things that broke was the RHF suspension
upright which is cast aluminum, it snapped just above the bottom
ball joint.
Sounds nasty.

Its a fairly rare part so he's been asking around about it and
several people have suggested welding it, the owner doesn't like
the idea and neither do I but one of the people who suggested
welding has apparently done it successfully before.
Does welding an upright sound feasible to you?
It's something I'd need to look at before making a call. It could
be. It would depend a hell of a lot on the composition of the
component.
Post by Daryl
I'd be too scared of it breaking at high speed on the track?
Is it possible that the weld could be stronger than the OE casting?
I'm not sure about it being stronger, but it could possibly be as
strong as an original part. It would all depend on whether the part
was a casting or a forging.
Cast alloy is reasonably strong, but it can be a complete pig to
weld well because of the typically horrendous make up of the
material itself. Apart from Aluminium, you get other materials in
the mix such as tin, iron, copper, Silicone, magnesium and zinc,
which all exist as alloying elements. They do their job in melding
it all together to allow the part to be cast and machined, but the
material is quite "dirty" from a welder's standpoint making it
quite difficult to get a good, solid weld.

That's what the owner is doing, he is against welding so it won't be
welded unless there is no other option.

I always hated the driving position in the 911. Particularly the
earlier models. The pedals felt wrong, the steering wheel came out
of the dash at a funny angle, and the steering feel itself was odd.
They got better as they got newer, but to me the early ones always
felt like a kit car.
I suppose all the pix of Gibbons behind the wheel of those Porsches
are in that sea-trunk marked 'EMPTY'.
What a clown he is.
and another to add to the long list of never to be seen photos.. his
Honda sponsored trip to Japan. one would think there would be a group
shot of attendees at least, and some happy touristy shots.
Why do you assume that people would have photos
usually on those corporate ventures lots of photos are taken, if for no
other reason than publicity and advertising.
It's Ok, Darren has never been to Japan, with Honda or independently.
All he's doing is repeating shit he's heard from others. He does this
all the time. I mean, just look at how he channels John Cadogan every
single time he posts yet he claims never to watch Cadogans VLogs.

No reason they should have photos, I take very few photos despite having

Noddy's description of older Porsche pedal and steering wheel positions
and them having an odd driving position is spot on, its the first thing
you notice when you sit in the drivers seat of an old 911.
They are quirky cars which you either like or dislike, I happen to like

Well that settles the issue folks! Because Fraudster accurately
described the eccentric driving position of old 911s this unequivocally
proves that the Bumhole (Vic) Boofhead has driven some. Case closed.
Move along. Nothing to see here.

Jaysus Deryl! Given that your little mate is a *proven* serial liar, did
the possibility that he's plagiarised that little fact ever rattle
around your skull??

If Fraudster wasn't such a tight-arse I'd suspect that he pays you for
your 'support' Deryl.

Now, back to photos & phraud... Ok Fraudster, as you're so
security-aware you really should have some pix of your fabled Grange
collection saved somewhere handy for insurance purposes, so it should
be an absolute doddle for you to post 'em to settle that challenged
claim. Let's see 'em!

It was a consequence of their design, being based on one of the worst
handling cars ever made, the Volkswagen Beetle, and it's precisely why
Porsche wanted to drop the overhanging rear engine for decades.The only
reason they didn't was because the fans revolted.
I don't think that the overhanging engine was necessarily the worst
decision in the Beetle, the swing axles were just as bad.

The swing axles were the number one reason why Beetles could be sat on
their roof with ridiculous ease as it was an *appallingly* bad
suspension arrangement that was outright dangerous. The rear overhang
engine didn't bother the average Beetle as they never made enough power
to be dangerous. However add a few hundred more horsepower in a very
similar chassis arrangement and it could be a handful for even the most
experienced driver :)

the MG corners better/faster than the Lancer did. I guess that's due
to the short wheel base and wider tyres.
In part. Suspension kinematics play a greater role these days. Your
current MG has a torsion beam rear suspension, a type that could not
be designed before the advent of computer modelling. IIRC, your MG3
was the same. As I have stated in the past, they are a compromise in
handling and ride but the coils are easy to *tune* and the kinematics
of the trailing arms are simple but effective. They are not new. Fiat
has used the torsion beam rear since the early 80s on the Uno since it
gives a good *space* configuration in compact wagons, hatches and SUVs
but still provide good handling. For instance, Peugeot 308 uses the
torsion beam for its handling characteristics. Even the moose test
wasn't a problem;
http://youtu.be/jMzaufUquys
Handling has come a long way.
**Indeed. Back in the early 1980s, I took a mate's Porsche 911T (2.7L)
for a spin. It was, by a considerable margin, the most exciting,
engaging car I had ever driven. Quick, precise and great handling. A
couple of years ago, another mate called in with his classic Porsche
911T (2.7L). He took me for a spin. What a POS. Slow, average handling
and big disappointment. Same car. 40 years difference. And torsion bar
rear suspension. My 23 year old Stagea kills the old Porsche in every
department. Except for styling. Oh, and NEVER drive an old Porsche in
the wet. You know why. In my Stagea (AWD), I don't even notice wet roads.
What an odd thing to say, I've driven a 1979 911 SC in the wet and never
had an issue but I wasn't driving like I stole it.

And I was being precise. I could have used the term *twist beam* but
torsion beam is less of a slang term and more of an engineering term.
Sure, the beam twists, but so does a torsion bar and, it has to be said,
so does a coil spring - if you think carefully about it.

I notice Keith went to Google to check up on my bona fides. I saw that
article but declined to use it as it merely listed the total of pros and
cons without much of an explanation. The book from which I quoted gave
the precise advantages and disadvantages that were *relevant* to this
discussion. It's a book that I used as a text reference in my teaching
days and it still comes in handy today. Pity there isn't a pdf version
on-line, would make citing bits and pieces much easier.

Torsion BEAM suspension (also known as twist beam) is not torsion BAR
suspension. It's a semi independent suspension cheaper than the real thing.

wikipedia.org/wiki/Twist-beam_rear_suspension

Pro
- Low cost
- Can be durable
- Fewer bushings than multi-link suspension, and bushings are less prone
to stress and wear
- Simplicity
- Reduces clutter under floor
- Fairly light weight
- Springs and shocks can be light and low cost
- May not need a separate anti-roll bar, as the axle itself may be made
to perform that function, up to a point
- Road handling can be excellent, often to the detriment of comfort
(examples: Honda Civic Type R FK2, Suzuki Swift Sport, Renault Clio III
RS, Peugeot 308 II GTi)

Cons
- Basic toe vs. lateral force characteristic is oversteer
- Since toe characteristics may be unsuitable, adding toe-control
bushings may be expensive
- Camber characteristics are very limited
- Not very easy to adjust for reduced roll stiffness, but increasing it
is easily done by adding an anti-roll bar
- Welds see a lot of fatigue, may need a lot of development
- Not much recession compliance: can be poor for impact harshness, and
will cause unwelcome toe changes (steer effects)
- Wheel moves forward as it rises; can also be poor for impact harshness
(this can be negated by designing the beam with the mounts higher than
the stub axles, which impacts on the floorpan height, and causes more
roll oversteer)
- Need to package room for exhaust and so on past the cross beam
- Camber compliance may be high
- No redress for wheel alignment. Alignment geometry is factory-set and
not generally adjustable. Any deviation from factory
specifications/tolerances could mean a bent axle or compromised mounting
points.

My 1993 Pontiac Grand Am had similar rear suspension, I wouldn't say
that that was in any way an endorsement of the design.

Torsion BEAM suspension (also known as twist beam) is not torsion BAR
suspension.
It is *exactly* the same principal as any torsion bar suspension system
with the exception that a torsion bar system usually links the two
wheels of an axle together mechanically and relies on the flex of the
link to supply the spring medium, as opposed to a torsion bar system
where each wheel is usually sprung independently of each other.

It's little more than an extension of your average sway bar, and is
about as cheap and nasty a suspension system as you can get. It's been
around for over 50 years. There is nothing "computer specific" about
it's design, and claiming that it couldn't have existed before computer
modelling is an absolute nonsense :)

Totally different *principle*! Torsion beam suspensions typically use
coil springs as their suspension medium.

You really don't understand the torsion bar system on a VW, do you? Your
above bullshit comments proves that beyond a shadow of doubt. The
torsion bar system, any of them, have a single torsion bar for each
wheel, even the VWs and Porsches of this world. Each torsion bar has an
*anchor* at one end and a free swivel at the other. Seems you've never
worked on them. Note, there are two torsion bars at the rear of VWs and
Porsches, one for each side - it's a true IRS system.

Uh, no! It's an extension of your typical trailing arm suspension - the
addition of a *connecting link* that limits some of the nastier

I said the designs required computer modelling - and they did. Still do
to this day. A lot of the technology you see on cars today used and
relied on computer modelling in its design stages.

Ah, poor desperate Darren, lost your street cred and are now desperately
seeking some. Sorry, not here Darren, you're just a *confirmed* bullshitter!

It took me a while to find a relevant book on the topic but let me quote
a pertinent paragraph from it here;

The optimization of a compound-beam design, where the trailing
arms must be laterally and torsionally elastic as well, cannot
be achieved by manual techniques and depends heavily upon
finite element stress analysis (see chapter 6) of the complete
welded assembly. The selection of the geometry for bump steer,
roll steer, roll camber, deflection steer and the roll-centre
height also requires the use of advanced, dynamic computer
modelling.

The above paragraph is from the book;

Chassis And Suspension Engineering
Road and Track Theory and Practice
By Geoffrey Howard 1987

I have the 1989 reprint so I've had it for quite a while.

Now, in the above cited text, chapter 6 is referenced. What is chapter 6
all about? Well, the title is "Computer aids and design techniques".
I'll cite a few pertinent paragraphs on the first page of the chapter;

Although the first use of computers in suspension
design and development dates back 20 years, rapid and
recent advances in graphic displays, measurement
techniques and processing time are putting a new
emphasis and value on the results of interactive studies.
Today, the visual display unit linked to a powerful,
high speed computer running advanced, dynamic suspension
and vehicle models are the basic tools of the
suspension-design trade.
Computer aids in suspension design eliminate much of
the guesswork, empirical measurement and practically all
the tedious calculations that were required previously
to determine safe stress levels and acceptable durability
standards as the preliminary stages to a new system
design. Carefully-developed programmes allow the
thousands of simultaneous equations of dynamic movement
to be solved rapidly, and advanced computer graphics are
used regularly to simulate actual parts in action under
strain, showing differences in stress levels, by keyed
colour graduations, like a thermal-image picture of heat
radiation. Three-dimensional representations also act as
valuable visual aids to the experienced eye of a
component engineer working on a new design, with
light-source angle of view and magnification all under
keyboard control.
This kind of computer-aided design (cad) is currently
being integrated with computer-aided manufacture (cam)
into a new operating science known as computer-integrated
engineering (cie). It is having dramatic effects on the
whole process of creating new vehicles and components,
and updating existing models.
Stress analysis for both the supporting elements of
the integral body/chassis unit and each component part
of the suspension system is performed with impressive
accuracy by a mesh of finite elements (fe) built up into
a framework of several thousand, finely-detailed,
interlinked struts forming triangles, squares and
rectangles. From the first application of fe programmes,
used to handle only discrete parts of a full system, new
tools have been developed that can simulate the
considerably more complex models required to represent
authentic dynamic behaviour.
Early fe work was limited originally to stress and
strain calculations by the inability of the computer
systems to handle the non-linear events and relatively
large displacements typical of vehicle suspensions under
dynamic loads. Setting up representative mathematical
equations of motion for the interrelated parts was too
complex and time consuming for the skills and abilities
of the engineering department staffs. However, with the
new generation computers came automated and
user-friendly programming interfaces that eliminated
the tedium and lowered the threshold of acceptance by
traditional mechanical engineers.

As I said in a previous post, my first experience of fe stress analysis
suspension modelling work was at the GM Development Labs in Fishermans
Bend. It was on a Camira which had a *ram* under the left front wheel
and the ram was pumping the suspension as if the car were running on a
corrugated outback road and the results of the effects displayed as a
wireframe graphic on a large monochrome monitor. At the time I was
amazed to see just how far and wide the vibrations travelled throughout
the car body. At the time what I was seeing was cutting edge technology,
the colour displays, mentioned in the text above, yet to appear.

So Darren, in all his ignorance, can shout from the treetops that what I
said was bullshit but, unlike him, I have the proof right here at my
fingertips. I have another text on the same topic but I have yet to
locate that but this will suffice.

BTW, the software used by the engineers was this and is referenced in
the book, obviously a much earlier version

https://en.wikipedia.org/wiki/MSC_Adams

The original creator of the software was a company called Mechanical
Dynamics Inc. and they were taken over/bought by MSC in 2002.

I beg to differ here. The *primary function* of the torsion beam is to
control the kinematics of the rear trailing arm suspension elements.
That it provides a form of anti-roll bar is mere happenstance. If you
have a separate anti-roll bar, you can tune the handling. The compliance
in the torsion beam has just one setting - that which is *engineered in*
at the design stage. If you want to tune the rear end handling from
stock, you need to add a separate anti-roll bar. The system has limits
which is why some are fitted with kinematic toe control bushings at the
primary pivot.

Darren is obviously only just learning about torsion beam suspensions,
hence his mistaking them for torsion bar suspensions, despite them being
fitted to *many* mass manufactured cars over the past 50 years. Poor
sod, he actually thought I was referring to a torsion bar suspension.
Should have studied harder in year 9 and he may just have qualified to
sign up for an apprenticeship.

Nothing astonishes Noddy so much as common sense and plain dealing.

the MG corners better/faster than the Lancer did. I guess that's due
to the short wheel base and wider tyres.
In part. Suspension kinematics play a greater role these days. Your
current MG has a torsion beam rear suspension, a type that could not
be designed before the advent of computer modelling.
What computer designed the torsion bar rear suspension on my old 1969
Renault?
A torsion *bar* suspension is little more than a coil spring suspension
with the coils unwound and straightened out.
