for SPL helping my projects to reach their potential. I am going to relocate the forward pivot of the lower control arm to reduce anti squat in the geometry. This should help the car hook up better out of the turns, have a more controlable progression to oversteer and eliminate all of the Z32's tendency to wheel hop.
SPL parts are awsome and are nearly manditory for serious track use. The flexabilty for roll center placment and rear toe cuve and overall bump steer adjustment is a huge advantage.
