I wanted a bit more brake than the XP-12's were providing, so I switched to the XP-20's halfway through instructing for Tarheel BMW on VIR North. The XP-20's were definitely a step above in terms of bite, modulation, and outright braking. I could easily enter threshold braking and further compress my braking zones. It was wonderful, until they overheated and I boiled the Castrol SRF in the right caliper.
They got so hot, they massively discolored my calipers.
After I bled the air out of the right caliper, I noticed heavy material x-fer on the rotors, which caused a massive vibration under heavy braking during my next session.
I decided to park the car and missed the last several sessions.
Carbotech said the system overheated and the rotors needed to be turned.
So until the 20's wear out, I will have to modulate my braking, then go back to XP-12's, or find a way to introduce more cooling into the front brakes wither through ductwork, better rotors (probably AP Racing), titanium shims, or all of the above.
So, word of warning, the OEM system works well up to a point, If you track be cognizant that you will likely need better brake cooling if running very aggressive pads.
The XP-12's seem to be about as aggressive as you can go with the stock setup as they never overheated the system.
