The front and sides are fine, howevevr, I hate the replica M5 rear bumpers. They have an annoying bow in the middle that is so visible, the front bumpers have it too, but since they are lower it's hardly visible. The rears have it and it sits right about eye level for the car behind you and it looks stupid. Best bet would be to find a used OEM M5 rear on eBay, I got a used OEM for my old 530.
