I have a B5 1.8 and had purchased the car with a S4 bumper already on it. I recently picked up the sideskirts and the back lip as well. The guy who sold them to me said I might need some kind of filler and a couple extra screws to bolt everything on. Has anybody had experience with this? Do I need extra material or should the skirts bolt right on where the black moldings are now? Any help would be appreciated. Thanks.
