rwd focus is fun, would love to do one myself, kugel komponents do a bolt in kit to convert a focus to rwd, not to bad on price either, i took their red focus out for a test drive, it did pull well, but then it should wth a 420hp 5.0 v8, here is a british one though having some fun, maybe even a member on here.
