PFC uses metallurgy and mass displacement technology to increase the rotor's resistance to heat and water fade, while improving braking power (torque) and responsiveness (bite). A special machining process is used to assure the lowest possible runout and thickness variation. Available in both a one piece and the new two piece floating rotor PFC will dramatically improve the breaking abilities of your vehicle. Both tested on the street as well as the race track PFC has cutting edge technology.
