This guy just purchased my 08 997 brakes for his 01.5 S4. He's mechanic is an old timers whos not too fond of aftermarket upgrades. He said that he has to have an adapter custom made. Is this true? I thought they were bolt up?!?!?

anyone know about this or have done it?

I believe Apikol sells a caliper bracket for Porsche calipers for Audi's. I don't know if that particular caliper will fit but I've seen other Porsche calipers used.
