Ok, so I got an 05GC which got the 12.6" F and 12.1" R disk. I been looking around for some after market for a drill and slotted replacement for as little $ as I can. Beside R1Concept can anyone recomment anything else?
I also know that the Brembo disk is around 12.7". Will it fit??? Thanks

 

Disc Brakes Australia 4000 rotors. Go to Autoanything.com

 

The whole 12.7/12.6" issue comes from how they round up or down on their conversion. The rotor size is really 320mm, which converst to 12.6" but some people list it as 12.7.

Take a look at RacingBrake rotors:
