hi, I have had my c32 2002 for a couple of years. Sometimes use it on track days and it goes very well. bu it does suffer from understeer. I run 19" rims. and the car runs well on them. However the car began to suffer from suspension sag at the nsr which would occasionally rub the tyre when loaded up. So they fitted larger sized rubbers under the springs which has in turn made the handling considerably worse. and now 6 months later is rubbing again. After taking the car to the Nurburgring and suffering huge understeer I really want to upgrade the suspension, maybe stiffer springs or a complete kit. I spoke to a German out there and he mentioned some kind of Ring suspension (Nurburgring). Anybody know of it?
Any suggestions

 

Have you worked with different tire pressures, to see if that played any part in your understeer problems, usually higher pressure in the front tires will tend to make a car oversteer, and equal pressure on all 4 tires will tend to make a car steer neutral. Also, do you have separate race tires and street tires?
