Our PFC Big Brake Kit Replacement Disc Assembly is a replacement for Performance Friction big brake kits only.
This PFC Replacement Disc Assembly comes with a new mounting hat, and it arrives fully assembled. Direct Drive rotors are made from a precision casting; all external surfaces are machined to tolerances of 0.004", including the OD of the vein area that most manufacturers leave rough-cast. This is the only rotor that is mechanically, thermally, and dynamically balanced - meaning you will never warp them because they are balanced in all situations, all temperatures.
Performance Friction’s higher precision and tolerances give you a rotor that will reduce drag, eliminate pulsation and vibration, and reduce heat transfer, as well as offering very low wear rates. This newest rotor design reduces weight even further compared to the already-light previous-generation components.
Note: We recommend using ONLY Performance Friction pads in conjunction with Direct Drive rotors.
