PFC 01 COMPOUND The Performance Friction PFC 01 compound is the standard by which all other racing brake pads are judged. The PFC 01 has a very high initial bite and torque, with very little temperature-induced torque rise. At the end of braking, less torque scatter exists for improved modulation and excellent release. With its low-wear characteristics and excellent disc conditioning properties, it's no wonder the PFC 01 compound has won more World and National Championships than any other brake pad on the market!
