Hey guys, just noticed what looks like two bulges in the rear bumper of the car just under the taillights.. never noticed before and doesn’t look too bad (at least it’s evened out on both sides) which led me to wonder whether all z4 rear bumpers had the two slight bulges or if it’s just mine and indicative of a previous rear end collision? I ran my fingers across and it isn’t too prominent/noticeable but if it’s not normal would it take a lot to get fixed?
