umm negitve camber is good for cornering but will reduce the life of ur tyres and can be achived through a wheel alignment,
L and S are good but very busy i can't even get a alignment atm go and hav a chat to lachlin and tell him what u want from ur car as for tourque steer i think a lsd helps alot and maybe a stiff steerting rack so its harder to turn, semi slicks are also a good idea i think
