I have a 95 caprice 9c1. I have 20'' rims I want to put on, but theres too much space. The 9c1 rear springs I got are way too high, and I want to lower it, but all the listings are for stock height springs. My question is- If I was at stock height, how much could I lower the car before it rubs? My tire size is 255/35ZR20 Anybody know? Would a 2'' drop rub? Guys put on 22s w/o rub. whats the lowest possible w/o cutting?
