smoothed prodrive bumper??

After seeing this guy's car at pvs I really want to do the same to mine and smooth out the font bumper where the plate sits, but don't know where to put the plate once I've done it. The guy at pvs had his plate in view behind his Sun visor but ain't sure if it's legal to do this

..........opinions and advise welcome :)


If you look at the bottom mesh, it looks like there are two screws in there where the number place would attach to.

Looks superb though!
