Sorry I can't answer your question but have always been curious myself. Would love see a real world test of before and after using these parts against an all new rebuilt suspension. Depending on driving habits I think all new urethane bushings, new springs, quality tires and shocks and most of all a quality sway bar may be enough to accomplish that better handling. Looking forward to other peoples comments. I know the sky is the limit on all of the aftermarket parts out there,which is a good thing don't get me wrong, but the problem for most people is budget and getting your bang for the buck.
