Very interesting approach that I'll look into as well. Though I don't want to run catless DPs for pesky VA emissions regs.
What race pads did you run? I'm considering many options, including Carbotechs but those are not friendly with racingbrake rotors so would have either run another rotor brand, or stick with OEM. Other pad options are Project Mu, Hawk, and Racingbrake's own XT compound.
