Bought to replace a broken bumper bracket. It's made of strong stuff but having read of a problem on the Z4 forum I was ready for it. It has extra plastic where you really don't want it. 2 little plastic ridges that stop the bumper from clipping in. I as others have done got a small file & removed the excess plastic. Once filed down the bumper clipped in perfectly so with a little bit of work it will fit. Even with this problem I would still recommended it.
