marc petillos car had the subframe welded on instead of bushings... still had wheelhop. i think its really the upper and lower control arms that are the main factor.. thats why i want to know if cobra poly bushings will work...
As has been said changing the bushing durometer will effect the handeling characteristics of the SC. The wheels are made to tow under hard cornering in essence making the car more predictable and have less of a tendancy to swing out. Almost like a crude 4 way steering if you will. so Many will say DO NOT CHANGE THEM!
As I have stated before wheel hop is due to drive train resonance. While bracing and changing bushings and etc etc etc may mask the symptoms, they are NOT stopping the source of the problem. Stiffening the rear LCA front bushing is a VERY bad idea for the reason stated by Damon. You are essentially defeating the purpose of the toe link compensator. If you chose to do so it might work out fine straight line but expect abrupt sharp transitions from neutral or slight understeer to oversteer in the twisties.
