I ran CMP in my Supra, and I will not go back unless I have a full brake upgrade (Z06 or Supra). I had full brake ducting, new rotors, and motul 600. The dust boots dissentagrated, rotors cracked, and every time I came off the track the brakes were literally smoking... even after a full cool down lap. Had to drive around the parking area to get them cool enough to stop. The freind I was with boiled motul 600 
I have run at Roebling and VIR without major brake issues.

I ordered the DRM radiator/oil cooler, and the DRM "short stop" kit last week just before this event- anxiously awaiting their arrival. The short stop kit has the DRM brake ducts, stainless caliper pistons and stainless lines. I already run Motul 600, so 2 more bottles of that will be great! I hope to have all this installed for VIR in June with MazdaDrivers.
I did order my replacement rotors from rockauto.com, so that's what I used at the track to swap out the cracked right front rotor and swapped the left one just for good measure.
With the new rotors on the car, it took 4-5 laps to get them bedded in, and once I started really hitting the brakes, the car was all over the place under deceleration. lap 5-6 the car finally started getting stable.
The Z06 is an awesome track weapon and is fiercesomely fast, even stock. I really need to get a set of wheel/R-compounds to take advantage of the car's strengths, as I was having a helluva time keeping the car straight this weekend. Don't get me wrong - power-on oversteer is fun, but doesn't do the laptimes any good.
I was actually much smoother driving with TC/AH OFF than in Comp mode, as I knew the computer nanny wasn't there to save me. It really forced me to be smooth on the brakes, and smooth applying throttle, but my best lap times were when I was going "commando".
Thanks for all the feedback fellas!
