They are done by True Design in colorado,Brian is the middle man. They don't stick out too bad,I have a customers car at my house now and his are 10 inch GNX style and I don't see any mods to the wheel well at all. Only complaint I have is the ones on my personal Gn were done in 06 and 2 are out of round(lips are not bent) worst is .031 so another $350 or so per wheel to repair.
