I did a search & still have some questions, I am interested in buying a CTR rear upper spoiler (replica) with brake light. does anyone have experiences with them - if so please post. They are available in ABS plastic or Fiberglass, any suggestions to which one might be better. I heard that fiberglass MIGHT fit better but can crack easier but is this really a problem for a rear UPPER spoiler? Also is the west wing version ABS or fiberglass? Also if anyone knows of a spoiler kit that is incomplete pls letme know so I can stay away from it thanks
