I can make you the real-deal in fiberglass......but if you're dead-set on urethane GPwerks is almost done getting set up to re-produce the old F2 bumpers. All I have to say on that, is if you research there was problems with fitment with the F2 bumpers, GPWerks bought those molds and that's what they are producing....just a buyer-beware type deal. Additionally, with GPWerks you can get one that is made to fit standard fenders (non-widebody)....I do not offer that option. mine are exact copies of OEM focus RS pieces.
