Hey Brad,
Yeah I actually use low boost which is 9 - 10psi (round 200rwkw) at the track just to keep things a bit, well, looked after as my car and motor are basically stock!
Suspension is ok I guess? I did a day at OP North on sat, only understeered in the wet/damp parts, but sat pretty well when dried out. Didnt open wheel this time either but I just feel I need a bit more front camber. Duncan told me about that temp guage thingy for tyres! Yeah would be good to use one!
