Released in 2001,this compound has increased initial bite and improved modulation. The friction level has been increased for the first two-thirds of the braking event, with a flatter torque curve and more linear friction curve. This allows the driver to attack the brake pedal later, reducing the time spent on the brakes. Very smooth release will not over-slow the car, and won't overwhelm the car's set-up. Like 97 compound, 01 has excellent modulation characteristics that improve controllability and driver confidence. The 01 uses Performance Friction?s unique lubrication package that maintains a minimal transfer layer on the disc to help prevent brake judder and provide excellent release properties, therefore reducing overall drag in the brake system. 01 is extremely easy on the discs with very low wear. Effective from 167?F and reach 2000?F (75?C , reach 1100?C), optimum operating range is between 860?F and 1004?F (460?C and 540?C).
