Hey Ivo, are you looking to reduce the gap in the bumper to wing?
if so then remove the bumper and unclip the little tab of plastic that the side screws go into, use pliers with a cloth to straighten and bend up the bracket (thats part of the wing) and then re-assemble and you bumper will be pulled snug!
After all the work we are doing on tuning my car, wich is amazing, i thought not to call and bother you with this question. So i thought lets put it on ek9.org....
