I don't see how he was able to get a 15" rim to fit over the brakes on the front wheels, unless he changed the size of the rotor to a smaller one.. I think that's why Ford went with a 17" rim, is because of the diameter of the rotor and the caliper..
Those wheels in the first pic are not 15" diameter. Those wheels are WELD XP's and are 17" diameter wheels. The car in that pic used to belong to Rob from QMP...
Those I believe are actually Boyd Coddington wheels. The center cap I believe is a Boyd center cap. They resemble the Signature Series - Quasi wheels, but don't have the groove on the spokes...
