Spent some time inspecting the brakes after the event and found very little wear. Pads are at 18.88mm thickness vs 20mm new. Rotors show slight heat checks but have no measurable wear or cracks.

GREAT write up Jared. We hope we can help you reduce lap times further.

Your rotor looks like they aren't making full contact on the outter side. Is yours creating a lip?

Pads do make contact right up to the edge. Pad is shy of rotor OD by 0.5mm or less - it's pretty spot on.

What do you have in the rear for brakes?

Thanks!

^Currently running stock rotors, stock calipers, and Cobalt XR3 pads - no ducting. Works well but I may try more aggressive rear pads once these wear out to better match the DTC70's in the front.

And your not destroying rear pads? I'm eating through rears very quickly

With stock front rotors/calipers, I'd get 12-15 20 minute sessions on front pads (XR2's) and almost double that on the rears (XR3's). I don't have enough data to determine rear wear with the AP Racing fronts but my XR3 rears had 16 sessions on them when I installed the AP fronts. They now have 26 sessions on them and 5mm of pad material left. I'll probably get one more weekend out of the rears.

A bit of an update after 6 days of Time Trial competition in NASA TT2 including 3 different tracks, new track records and winning the 2014 NASA NW championship.
Pads have over 10 mm of friction material left and left caliper temperature indicator finally registered the lowest temperature level of 300 F. Right caliper temperature indicator still hasn't registered anything. Rotors are looking good. No measurable pad taper.
Super impressed with this kit.

Curious if anyone has cracked a rotor with these? I popped 3 stock rotors in one weekend at Road Atlanta and am getting pretty tired of doing a hot swap between sessions...
