PolyMatrix C Compound

Pad Characteristics

  • Medium to medium high friction compound with soft middle temperature response and a gradual rise to a flat torque curve as temperatures increase.
  • Long wear rate for severe-duty, sustained high-temperature braking.
  • Reduced friction alternative to B.

Pad Applications

  • Race ONLY compound commonly used to reduce bias against A, B, or H compounds when additional hydraulic adjustments are not available.
  • Use on any lightweight vehicle, including dirt applications, with high mechanical advantage brakes to prevent wheel lock-up in marginal traction conditions.

The above friction data (μ) was recorded through braking cycles from 95 mph to 40 mph at a 0.5g deceleration. Snubs were consecutively done until rotor temperature reached 1300°F. This graph represents average data and is for general trend visualisations only comparing Wilwood pads. Chart data should not be used in comparison with other manufacturer's data. Test conditions, variables, and environment can affect test results.

Temperature range and overall friction value are the primary considerations for pad selection. The pads must maintain the proper amount of friction for stopping power within the temperatures that will be realized on the track. Overall wear rate must also be considered. For most asphalt and road race applications, compounds in the high-temperature range over 1000°F are usually necessary. Dirt track, drag race, and street performance applications usually operate at temperatures between 500° and 1000°F. Keep in mind that these are general ranges and not absolute values. Many factors and unforeseen influences can affect brake temperatures. The best indicator for pad selection will always be on-track performance. If pad fade (friction loss) due to overheating occurs, improved cooling, a heavier rotor, or a higher temperature range pad may become necessary.

Forged Dynalite-ST Calipers

The Forged Billet Dynalite/ST has been specifically designed for high temperature road racing series compact cars. Teamed with Wilwood’s exclusive Thermlock insulated pistons, it gives a small size, high temperature solution for rotors in the 12.19” to 11.00” ranges. The Forged Dynalite are the strongest calipers in the class, with weights starting at 2.90 pounds. The process of stress-flow forging re-aligns the metal's grain structure within the contour of the caliper body. This process eliminates the breaks and interruptions to the internal grain structure that occur when machining a straight block billet. The FEA generated radial transition design eliminates steps and shoulders in the area between the piston housing body and the caliper bridges. With the overall greater strength and reliability of the forging, the reduced deflection tendencies and the resulting decrease in fluid volume displacement translate to increased clamping efficiency with less pedal travel. The bottom line is a taller pedal and better stopping power. View Forged Dynalite Calipers
