slp vs. hd's
what is the difference between the bilstein hd's and the custom valved slp bilstein's. which one would be better for autocrossing? is one set up for stock replacement, and one for lowered vehicles?
also, is there a common opinion on the differences between the eibach pro kit and the hotckis progressive rate springs?
