PFC has put decades into research and development, and incorporated that knowledge into ground-level savvy gained from their successes in motorsports. The result is an engineering marvel — the patented PFC Rotor. This part is a direct replacement for original equipment rotors and works with original calipers. The unique Performance Friction slotted rotors use a combination of breakthrough technologies to eliminate noise and enhance rotor life. * Special machining process assures the lowest possible runout and thickness variation. * Exclusive high temperature metal alloy resists hot spots and shrugs off the highest heat loading. * Computer designed vanes maximize cooling air flow and prevent thermal distortion. * Made from High Carbon Alloy with copper and molybdenum for high temperature strength and stability * Vanes (all 47) are turned on both ID and OD surfaces to reduce thermal warping and vibration * Runout less than 0.0005" and thickness variation less than 0.0002" to reduce pulsing and vibration * Surface finish less than 0.7 microns * Double-shear bobbin attachment to allow both radial and axial expansion. * Rebuildable with new rotor discs. Higher precision and tolerances give you a rotor that will reduce drag, eliminate pulsation and vibration, and reduce heat transfer. And, wear is increased as well! Two pounds per rotor lighter with a dimpled finish that performs similar to slotted discs but without the wear.

Replacement discs also available. * E46 M3 rear Direct Drive rotors require a Performance Friction 7855 pad for mounting bolt clearance . This shape can be found in our PFC pad listings in street, street/track, and 100% track compounds. Two piece floating rotors are race proven in major motorsports venues around the world.
