FWD race set-up
Discussion
Hi,
I've started helping a friend who races a FWD saloon, he bought the car mid-season and doesn't feel he's got to grips with it (we both come from a RWD background).
The car:-
800kg, 205 section slicks, front and rear anti roll bars, 600 lb springs front and rear, 2.5 deg front camber, 7 deg castor, parallel toe front and rear, front and rear shocks are a bit of an unknown (strut inserts at the front). Tyres 28F 24R.
The observation is that is generally not very responsive, turn-in being a little vague. Being light, the rears take a few laps to warm up so it oversteers on cold tyres but not so much when up to temperature. It sounds to me like it's a 'feel' thing.
Thoughts would be:
A few mm of toe out to help the turn in?
A little stiffer all round? (seems a little low on springs perhaps?)
Look into the dampers over the winter
Any thoughts please? Also, does anyone know the sort of set up touring cars run?
Thanks for reading!

Dear all,
Thank you very much for your feedback and thoughts on this, very much appreciated. Certainly there has been some common themes that we will be trying on a couple of pre-season testing sessions. It'll be a few weeks off yet but I will feedback our findings/thoughts when we have tried the changes you have suggested!
What would you suggest for front toe? My current thought is 1-2mm each side to help turn in?
Thanks again!
