The civic, a bmw, even an altima coupe, you name it… fender rolling in some cases if not most is the severed reworking of a fender and adding fiberglass to bring out a wider stance… its a simple add of ribs to the polys available and pushing the new ribs wider by its width access, and a gental smoothing… or pull all the verticies wider and bring forward or back the ribs for smoothing, has nothing to do with a body kit but the wheel well portion of the fender.
Alright peace…
Ps. also if you want to hire me im down.lol
