There is good information on the Vintage Wheels tech pages on backspacing and such. Superformance uses the original six pin design which are Vintage Wheels. If you had an orignal car with six pin, (6pin x 4.25)their wheels bolt right up. Same six pin pattern. They also have adapters to bolt up to 5 lug rotors and 5 on 4.5 ,5 on 4.75 patterns. Vintage Wheels makes a great knock-off, knock-off.
