jim ,looking at your rear wheel camber , is that bending the arm ,or set with no neggie?

Not sure if it's the photo but the front wheel looks to be neutral to me. I would have thought that 1.5 degrees up front and half a degree on the rear is about right? I've been thinking about the suspension setup for a while and that's what i came up with.

The rear definitely looks positive to me, unsure or the toe, that could just be the arches giving false impressions

Does that fact that the rear axis of the car is at about 5 degrees to the road not give you some clue about what the static camber is with that wheel unloaded and the car sat at rest??

im not comparing the wheel angle with the road tom , im comparing it with the side of the car . the rd is not a sensible reference in this case i feel ?

I never really noticed, but it could be looking at this pic, I have noticed the the camber bracket bending I suspect this is whats moving.

The car is set to have a degree of -ve camber and 30 mins toe out on the rear, the front is 2 deg -ve camber.

Maybe I need to mount a camera poiting at the rear wheel and see what happends on the track.


Can anyone think of any ideas how I can monitor the radius arm for bending? they are KAD ally ones.

ps I can't get enough sausgage

Longy will know all about this, but you could rig up a strain gauge. I can imagine its quite a complex setup, but there may be some basic setups available.

simply set up a probe that references on the inner rim lip and set back say 5mm , then see if it is rubbing after a session, ,

I recon its an optical illusion with the toe out, the roll, and the angle of the picture.

Don't know what arms you run, but the cast (standard and KAD) bend under heavey cornering, especialy with tyres like that.

Is it the arm that bends or the brackets/subby?

heres a thought, assuming its not an optical illusion, could the beam be bending and not the arms? assuming its only bolted on the outer edges (which i doubt) as it looks like the wheel off the deck has a bit of positive camber about it aswell lol

pretty basic idea jim , but what you could do is ,
get a piece of steel rod or box ,say 5mm diameter ,attach it to the arm near the wheel,so it sit vertically and make a slot in the shell so it comes inside the car ,then have a pointer on the in car end rubbing on a scale ,and them paint the scale . the idea being that any twist will make the pointer scrape the scale plate sideways .any pure up and down motion would just leave a vertical score .

edit to say ,this wont work becuase the swing of the arm would mean a fore and aft motion of about a ft lol,wouldnt want a metal pole spiking you in the ear .

a better option would be a short spike sticking out of the back of the hub centre with a plate bodyshell mounted at a right angle to the arm ,and a right angled bend on the end of the spike bearing on the plate .... ,this would show a straight line on a plate if it was only going up and down ,and a weird spirograph pattern if flexing ..

Denis, I'm pretty sure that Jim is running a rear sub frame, all be it slightly lightened.

some good ideas here.

I am using a rear subframe, It's not been lightned much at all. And it's solid mounted too.

I'll get the car on the lift in the next few weeks and put some strain on the stub axle and see what bends.

It does look like something is moving / bending somewhere.

The car was having loads of 1.4017g's on this corner, which was the greatest of all the corners at combe.

Interestling only .2g's more than a miglia on the same corner, but they don't have this problem, although they are not allowed to run ally arms.

Interestingly I was reading about the Honda BTCC car last night and it was talking about the rear suspension steering under load. But it is a deliberate design (even on the road car).

I guess you guys have seen the BTCC/STCC C30s..

Looks bloody strange.





I ccannot imagine that the tyre ever is flat against the ground.
What is the theory behind this?

The current Vauxhall Cavalier in the BTCC has similar rear wheel setup.

What the artical I was reading was saying is that there is too much rear grip, and you can't increase the front, so you need to reduce the rear. Honda went for the rear steer idea (so did others), but this looks like a cheaper and easier to tune idea.
