Rear camber question
Mix - 19/12/04 at 04:42 PM

A question for those with IRS.
What angle of rear camber are you running, / have you found best?

(It has a bearing on the width of my rear arches )

Horses for courses I think - you'll have to see what works best for you; with a 'tigerish' back end you might want a fair bit of negative to make up for its camber control!
I can't really comment 'til mine has seen some tarmac in anger.... but I think you'll have to choose between best cornering or tyre life.

In my version of 'tigerish' the wishbone geometry is corrected. (Divergent wishbones) so the camber change should always be -ve in bump.
I was just after some idea of where others had set their camber.

TBH, I would set the rear arches as if the wheels have no camber - i.e. 90 deg to the road surface. You wont be gaining any more than a couple of mm clearence using 'sensible' camber adjustment...

Mix,

Did you ever work out how to fix a Tiger rear end to sort the camber change out?

Yes, (well I think so)
It's not finished yet but basically I've made changes to the design of the upright, (mainly to make them easier to manufacture). Ditto the lower wishbones. The upper wishbones will be substatially different and their inner mounting is moved from on top of the tubes to the sides. This gives negative camber change in bump.

Mix,

Sounds interesting. Any drawings?

Cheers

Yes, quite a few, what are you interested in?

Mix,

I just want to fix my Avon rear end, or work out how to do it! Any suggestions?

Cheers

This solution retains the original upright and lower wishbone. The upper bone needs shortening and the brackets are repositioned.
I can't comment on how this will handle as I havn't driven it but at least the camber change is in the correct direction.
Ignore the left hand side, that was another option I was considering.
I'm also thinking of moving the tubes that the upper wishbone brackets are attached to inboard so as to increase the length of the upper wishbone.

Cheers Mick
