Seen a set done on a VR Senator. Factory look 17's but 10" wide. Done by dragway wheels in Thomastown. 3D scanned into the computer, then CNC machined from a solid billet then fitted to barrels (2 piece wheel). Guy wouldn't say how much only that he basically had to give them his first born daughter, his right nut and then on hand over blow jobs for all. Not worth it.
