I can only speak for the 3dr models but I presume the saffy's to be the same. Ford didnt fit standard bushes to the 3dr, they fitted spherical bushes insted...tbh they do look very standard, but retail at around £70 a peice and are much weightier than a normal bush. As such, polybushing aint an upgrade. Do a search on here...there's been a fair few threads on the subject, all coming to the same conclusion.
