I would say they are different. The Vader wing sides go out, thus giving a much wider appearance, and a longer shelf on top. The Amuse wing sides go in, making it look narrower. Plus I would not get anything Duraflex. You are better off ordering the Shine Auto Amuse Replica with CF.
The $250 you save by buying the Duraflex, will be spent at the body shop trying to get proper fitment.
