I purchased a used set of SVT rims for my 2000 SE sedan. One has a minor bend in it(must have taken a set or railroad tracks to fast LOL) and the others only have a small amount of rash on them. But now my car is vibrating like crazy when i go over 50 mph, and its gets worse up to about 65 mph. Is this most likely a balencing thing, a bent rims thing, or a alignment thing? plz help me!!!!
