Carbotech Performance Brakes, CT1039-XP12
Carbotech XP12 is a highly successful XP series compound with an excellent initial bite, torque and fade resistance over and above the XP10 compound. XP12 has temperature range of 250F to 2000F+ (121C to 1093C+) and is very popular with Time Attack drivers.
The XP12 compound has good modulation and is more rotor aggressive than XP10. XP12 is NOT recommended for use as a daily driven street pad due to elevated levels of dust and noise.
