chapter 2 If you install a spring say that is simular in length but heavier wire , with the same weight factor {engine/and optional equipment} the profile of the vechile may be slightly but ride would be harsher. The fact the the shocks are fully exstented sounds like you got too long a spring. Try and remember the control arms are just two parrell arms moving in a vertical motion.H=LENGHT R=WIRE SIZE hope this helps BILL
