As in the authentic widebody Focus RS body? Good luck with that one; it's super hard to find any of the pieces, let alone all of them. The prices because of the terrible exchange rate now will also bankrupt you. One of our sponsors, F2 Focus, makes a very good looking US-spec (meaning the bumpers aren't "stubby" like the European counterparts, which means you won't need to spend a ton of time/money on European crash foam and rebar) kit in either standard width or widebody variants.
