4 to 4.5 bolt pattern front discs
I had my rotors redrilled from 4" to 4.5" by Moser Eng way back in 2002. They machined off the old studs, redrilled for 4.5" and installed threaded studs. Been on the car since, no issues. If you go this route, on most 15" wheels, the ID of the wheel (center hole) will be larger than the OD of the hub hence, it will now be lug concentric instead of hub concentric. Been running like this for years w/no issues. They do sell hub concentric ring adapters to fill the void on the hub to wheel. Don't know if Moser still to it.
