Ag-Z06,
CMP is one of the hardest tracks out there on brakes! My guess would be that you are getting a little faster than you have been in the past and using more brake. Be sure to install DRM brake ducts and Phoenix or LGM spindle ducts.
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.
