I've contacted RiderRocketMan on this one ... he was using BST carbon fiber wheels (was as in his was that 231hp bike sold on eBay a few days ago that someone linked to). Seems they cost around $4k. Ouch.
These are the tires he has used on it (dark side), Bridgestone Potenza, Goodyear Eagle F1, and Yokohama 245/45ZR18.
He said that he didn't need to make changes for the rims, but did need 1/2" higher shocks for those tires and suggested something slimmer like a 235/50 or 225/55 if trying to avoid that.
