make the back softer than the front by a noticable amount . At very high speeds you want the car to understeer a bit, and be very stable. When braking hard, the rear end must not slide, and when puching out of a corner, the rear shouldnt wash out either. then you can concentrate on point and shoot driving style without worrying your rear end will step out.
