Just confirmed the 951 hub/spindle sets exactly same distance from axial caliper mounting face as NA hub/spindle.... 3.450"

Can you optionally run the 350 rotor with the 996t calipers, and will these also fit 86 951 spindles/hubs?

1.....Yes
2.....No

Will be doing the mockup tomorrow, but looks like these pads are a perfect fit on the 330 rotor sweep height.

I suppose you could maybe find a 4mm taller pad for the caliper to fit the sweep of the 350 cayenne rotor. Wilwoods Integras 6 pots do this. But the laws of diminishing returns have the 330 rotors and these pads at some serious stopping power for a 3000 lb car

Did the mock-up and we have a winner. I ordered a stick of 6061-T6 and will tap the adapter to re-use the factory M12 x 1.5 caliper bolts. PM if you'll want a set of these including the Cayenne rotor centering rings. Ill have them ready next week.

Final bit of wisdom.... Outer caliper face to outer rotor face is 2.26"

Yes. And the flange thickness of the Cayenne rotors are only 1mm thicker than 951/M030 rotors so wheel offset by +1mm as well. With Porsche the fenders can be off +/- 5mm lol.
Made a batch of new centering rings too. They are an absolute must and fit the Cayenne 350 rotors as well. Mine are 4140 steel and chamfered at the hub interface....
