Disc Technology

Disc Specifications  |  Two-Piece Direct Drive™  |  Continuous Fibre Carbon-Carbon

With over 7 years of design research and metallurgical development, Performance Friction was awarded 3 separate patents for our computer vision based machining process, full floating Direct Drive™ attachment system, and advanced slot pattern.  Since first hitting the track in 1998, PFC race discs have won more major championships than any other race disc on the market.  Ask any professional racer and you’ll learn about the numerous benefits of Performance Friction’s disc technology.

Being the leading disc manufacturer for all professional race series has its benefits.  Racing is the ultimate test of disc design, durability and functionality.  Our research and development for racing is directly related to how we manufacture our line of disc brake rotors for passenger cars, trucks, fleet vehicles and sports cars.  A combination of breakthrough proprietary technologies reduces vibration, eliminates noise and enhances rotor life.

Disc Specifications

• Patented slot pattern for more bite, improved release, more efficient pad cleaning and improved thermal stability [36 slots] 
• Patented dimple design for street applications gives quieter performance, while still maintaining the bite, release, pad cleaning and thermal stability characteristics of our slot pattern disc
• High Carbon Alloy with copper and molybdenum for high temperature strength and crack resistance
• Aircraft quality heat treatment for micro structure alignment and durability
• Runout less than .0005 inches and thickness variation less than .0002 inches reduces Judder and Pulsation
• Vanes turned OD and ID for balance to reduce thermal warping and vibration
• 47 or more vanes for superior thermal capacity
• Surface finish less than .7 microns
• 100% measured and inspected to meet strict tolerance specifications 

Two Piece Direct Drive™ Patented Disc Technology explained Ever since the disc brake was invented, vibration and pulsation caused by thermalexplansion (warped rotors) has been a major issue.  UNTIL NOW... With Performance Friction's two piece floating Direct Drive™ V1 disc, the disc flange floats in the bobbin structure allowing radial and axial expansion of the disc without being constrained by the hub or the hat. The benefits of this system include: more efficient torque takeout eliminates vibration and pulsation reduces piston knock-back improves control and release reduces heat transfer to hub assembly reduces drag and increases fuel mileage reusable hat/hub assembly longer life and lower cost per kilometre

AND NOW ... there's Direct Drive™ V2

The Result is ... Performance Friction Brakes outperforms the competition by more efficiently distributing heat for lower lap times, longer life and improved driver control

Continuous Fiber Carbon-Carbon Building on experience gained as the dominant pad and disc manufacturer in international motorsports, Performance Friction has launched a Carbon-Carbon program set to revolutionise the carbon brake market as they have done with the iron brake market.  "We have tested and achieved better cold temperature friction properties as well as longer life and better strength properties.  This advanced Carbon-Carbon has continuous wound fiber technology not previously seen in the race market," said Don Burgoon, President of Performance Friction.  "Combine the advancements in carbon technology with our championship winning Direct Drive™ attachment system and the result will truly change the way everyone in the motorsports community views the performance of Carbon-Carbon brakes," Darrick Dong, Director of Motorsports for Performance Friction.
