You mean the arch liners? Never really heard of it before tbh.
one on mine came off few months ago, wasnt attached properly at the front to the bumper so it caught the wind, now my horn dosnt work cos the rain has got to it lol
Mine come of when I went to the ring, probably spend a good 10 minutes above 100mph on the autobarn
Can see it here, it's dropped.
