About Performance Friction 2-piece Dimpled Floating Brake Discs

Ever since the disc brake was invented vibration and pulsation caused by thermal expansion (warped discs) has been a major issue.

Until Now…

With Performance Friction's two-piece floating Direct Drive Disc, the disc flange floats in the bobbin structure, allowing radial and axial expansion of the disc without being constrained by the hub or hat.

Direct Drive System

Years of R&D and thousands of professional championships have resulted in the development of PFC's
Patented Direct Drive System.

A true two piece floating race rotor optimized for road and track duty.

Key Benefits

• Reduced thermal distortion and warping.
• No rattling - 100% silent operation.
• Reduced drag and increased mileage.
• Reusable hat/hub assembly

Features

• High Carbon Alloy with copper and molybdenum for high temperature strength and durability.
• Vanes turned OD and ID for balance to reduce thermal warping and vibration.
• Run out less than .001 inches, reducing Pulsation and Vibration.
• Thickness variation less than .0003 inches reduces Vibration.
• 47 or more vanes for superior thermal capacity
• Aircraft quality heat-treated for microstructure alignment and durability.
• Surface finishes less than .7 microns.
• 100% measured and inspected to meet tolerance specifications.

Performance Friction Brakes outperform the competition by more efficiently distributing heat for
lower lap times, longer life and Improved driver control.
