Just did a trackday at Rockingham last Friday with my latest 172. My brake set up is standard discs and lines, RC6 pads front and EBC yellow rear, with Motul RBF600 fluid.
I started the day with no arch liners and fog lights removed, as well as carbon canister removed and horns re positioned. It was a hot day to start with, with temps between 25 and 30C throughout, but the brakes were faultless and didn't many a 15-20 minute stint without fade.
We were doing the Intrrnational circuit which is about 2.2 miles, and has 4 big braking areas per lap, the fastest one being 105-110 down to about 30.
For later sessions I removed the fog light covers completely, just to add extra venting although it didn't seem necessary.
@M.C.. Was also at the track day and he was running the CL RC6 pads, which seemed faultless for him also.
