Performance Friction Front Dimpled Rotors Subaru WRX STI 04-07

It’s Quicker. It’s Patented. It’s advanced technology that you can’t get anywhere else.

Performance Friction 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. The unique Performance Friction dimpled rotors use a combination of breakthrough technologies to eliminate noise and enhance rotor life.

Special machining process assures the lowest possible run-out and thickness variation.

Patented dimple design gives much higher brake bite.

Exclusive high temperature metal alloy resists hot spots and shrugs off the highest heat loading.

Rotor vanes turned OD and ID for balance to reduce thermal warping and vibration.

Two-piece, full floating, V2 Direct Drive attachment between rotor and hat

Rotors are precision machined from high carbon alloy rotor material, with molybdenum included for maximum temperature strength.

Aircraft quality heat treatment for micro structure alignment and durability.

Rotor run-out held to less than 0.0005-in., and thickness variation less than 0.0002-in.

100% measured and inspected to meet and hold tolerance specifications.

These two piece floating rotors are race proven in major motorsports venues around the world.

Sold as a pair (left and right).
