What are peoples thoughts and exeriences of racing with rear negative camber on a de dion car (caterham).
It should reduce oversteer a little if present from what I have read. Currently we are set a zero and wondering what to shim the de dion to as a starter.

Rear toe out is apparantly a big no no but has anyone actually given it a good go on the track, I've read one thread where apparantly a r400 racer won a lot of races with rear toe out.

Any thoughts?

I've driven with toe out on the rear. A well scary experience and in anything with any power and RWD you will soon be going backwards through a hedge IMHO!

I once bought an Imp with evil handling on right hand bends, it turned out the offside rear semi-trailing arm was slightly bent resulting in the rear toe-in going from a significant toe-in to a slight toe-out.

All that I've read suggests some toe in on the rear and always a no-no for any rear toe out.

My only experience was shimming the rear of my MK Indy to equalise and slightly increase the rear toe in. This gave a noticeable improvement in handling, particularly on sudden direction changes - e.g. entry/exit of roundabaouts.

Rear toe as others have posted .Rear and front camber dependent on tyres being Radial or Cross-plys. Up to three degrees for
Radials and half a degree for Cross-plys Cheers. Winston

Cross-ply still exists?

Xply is the dogs nutsack for racing. See Avon

As before toe out on rear is nasty, darts all over the place out of controll and then crashes. Avoid like the plague
