I don't even know who makes race compounds for the Z28 6 piston calipers... are there many options?


IIRC correct someone had an issue with a RB front cracking early (please don't quote me here) - Giro disc all round would be the way I'd lean as I have personally seen these on track with very fast / hard drivers hold up well.

Giro disc rings are 800 vs ZL1 rotors for 720 so it's pretty close. I don't know what pad options are for the rear yet.

The pads are identical in shape and I didn't observe any overhang - my understanding is that the 394mm rotors only had an effective surface area of 390.
