The home page linking to this thread says:Why would you assume just because the NFS has a lot of fake elements (which makes sense since it was made for a movie) that the S550 would also if it has some of its cues. Body kits are never gonna look as clean as integrated/original design.
That said I bet there will be more than a few cues. The 'coke bottle' look is there, slightly wider, big front splitter and rockers, large brake ducts and maybe losing the fake gas cap in the decklid. Yea the NFS one has a lot of fake shit but if they build it into the car and make it functional I don't see why it couldn't look good on the 2015.
