Specifications

                                                
1)  High Carbon Alloy with copper and molybdenum for high temperature strength
     and durability.

2)  Aircraft quality heat treated for micro structure alignment and durability.

3)  Runout less than .0005 inches and thickness variation less than .0002 inches
     reducing Pulsation and Vibration

4) Vanes turned OD and ID for balance to reduce thermal warping and vibration.

5) 47 or more vanes for superior thermal capacity.

6) Surface finish varience less than .7 microns.

7) 100% measured and inspected to meet strict tolerance specifications.



                             



Ever since the disc brake was invented vibration and pulsation caused by thermal expansion (warped rotors) has been a major issue.  Until the Two Piece Direct Drive patented disc technology.

With Performance Friction's NEW 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.

       * Eliminates vibration and pulsation

       * Reduces heat transfer to hub assembly

       * Reduces drag and increases fuel mileage

       * Reusable hat/hub assembly

Longer Life and Lower Cost Per Mile

Performance Friction Brake Discs outperform the competition by more efficiently distributing heat for lower lap times, longer life and improved driver control
