I have a '68 Fastback which I'm installing a Baer front disc brake conversion on. The car came with 14" aftermarket wheels. In the Baer instruction sheet, it said that with the 11" rotors in the kit, 14" wheels might not fit, and sure enough, they don't have quite enough clearance. I want to use American Racing Torque Thrust D wheels anyway, in a 15" rim diameter. My problem is that I don't know what backspace to use, and I also don't know if 15x7 wheels with 60-series tires will fit in the wheel wells. Does anyone out there have any experience with this? Any information will be greatly appreciated.
