I just got the rear kits. Each one comes with six shims. The directions states if you only use 2 shims you won't have to get longer bolts. I have eibach Pro-Kits, how many shims should I use?
Anybody else have these kits? The kits were only 45$! I also be runing 18 inch wheels. Any help would be greatly apreciated!
