Carbotech XP8 (1108)
A high torque brake compound with a wide operating temperature range (200F-1350F+). Carbotech XP8 is the first of our racing compounds. Outstanding initial bite at race temperatures, high coefficient of friction, excellent modulation and release characteristics. Extremely high fade resistance, very rotor friendly with 100% non-corrosive dust. Excellent as a front brake pad for lighter ITA, ITB, ITC, SRF, H4, H5, and other cars that weigh less than 2,400lbs. Perfect for novice, intermediate and advanced track day (HPDE) use with any tire, and can still be driven safely to and from the track. There are several vehicles that use XP8 on the street, autocross, and at track day (HPDE) events. Carbotech does NOT recommended XP8 as a daily driven street pad due to elevated levels of dust and noise. XP8 is also a great rear brake pad for almost any race car (Spec Miata-T1/T2/CMC). XP8 is a great compound on the front & rear of most open wheel and sports racers.
