Ex850R;36730 wroteAsh , i think i have asked before but is there any benefit in RX-7 calipers on x70?
Not really a workable solution on the P80 cars. the required rotor offset would mean we'd need to look at multi-piece 'real' rotor and hat arrangements. If you're going to that expense, you'd be best to look at a really nice serviceable caliper, like an Alcon, AP, etc
Porsche brakes are nice as you can make use of the S60R rotor which is fairly inexpensive.
The problem with that is that you can't make use of 17" wheels like a Titan or a Volan without running a spacer. This results in a big change in net offset, which isn't ideal.
S60R front calipers wont work on the front of the P80 either, as it would require machining of the back of the hub (IMO, bordering on unsafe).
