There is a quite detailed thread in this section, explaining the 850 caliper (same piston diameter as the 9 series) and the 302/305 rotor conversion for the 7/9. Not quite a 4 pot Wilwood upgrade with big rotors.... but an upgrade none the less. You do need a custom abutment bracket to make this work..... mine came from Skandix.DE

If the OP just wants to repair, certainly there are parts in the supply chain.
