We really need cooling ducts.

Also, I recently switched to the carbotech RP2 endurance pads, and in three days at Road Atlanta, the rear pads are already halfway gone. Granted they have about a third of the surface area of the front brembo pads, which look like new, other than the paint burned off of them, but come on!
Okay cool, that's good to know. I was worried about it and skipped the final session, doh! I think for my next HPDE (in the Fall), I'm definitely going to try to get some duct work for my brakes.

That isn't good news about the RP2's, I was really hoping they would prove to be much longer lasting than the XP's. Although as of right now, I'm pretty happy with the life of the XP's. I'm at about half pad life for all of them, with 3 HPDE days. However, my threshold braking needs work, so I bet that if I was to get another set, they would only last for 4 HPDE days.

How brutal is Road Atlanta on brakes? I've only been to Sebring so far. I'd hope to at least get 30% more life out of those compared to the XP's since they are specifically for endurance.
