wondering if anyone else has had this problem. i have the rk sport street fire bumper. when mounted to the car it sat like a half inch lower where it meets the top of the fender everywhere else fit great. with stock fenders i rolled them down to match by hand and looked fine. now i have glass z3s and the spots there on them aswell.. no rolling glass. sounds like alot of work to me. if i shave top of fender then i loose the hood to fender??? so i guess would fiberglass work for the build up to the fender on eurathane???
