yes I had Carbotech front and back and never had a problem with them, I remember last year running CMP and still did not have any problems, and my home track is Road Atlanta and also it is a hard track on brakes and the same no problems, one thing that we do with my car is that we bleed the brake after every session and we use Motul 600 and lots of brake colling ducts.
That is a great car and trust me that car is like new never run more than 4 or 5 races.
See you soon.
