I have heard the piece hit bottom a few times in the six months I've been driving. It isn't often, but three good hits was enough to damage it. It now has a small 4" crack where it meets the underside of the bumper in the center. I saw the same crack on another aero kit. That part is bound to get beat up more if it is any lower. What is the reason behind that part hanging down? Maybe you could cut it off If your going to drop your MINI.
