I have H&R sport springs, with stock shocks and the camber is way off. I installed K-Mac camber kit up front, and that helped, but the rears are still wearing the hell outta my tires! Will upgraded shocks help? If so, about how much are a set of good shocks?

try bimmerparts.com talk to chris, he was by far the cheapest, i think u should be able to get it from him , i got mine 2 weeks back from him

good luck
