Compound Data Sheet
Application:

  • 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.
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.
Compound Temperature Range & Torque Values
Temperature range and overall friction value are the primary considerations for pad selection. The pads must be capable of maintaining the proper amount of friction for stopping power within the temperatures that will be realized on the track during the event. Then, overall wear rate must be considered. For most asphalt and road race applications, compounds in the high temperature ranges over 1000°F range 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, then improved cooling, a heavier rotor, or a higher temperature range pad may all become necessary.

Forged Dynalite-ST Caliper

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

The Billet Dynalite caliper is powerful, compact, and super lightweight. Advanced computer engineering keeps this caliper extremely rigid resulting in incredible brake torque at a bare minimum in weight - only 2.5 pounds. Internal fluid crossover eliminates external tubes and the four position, two-piece bleed screws allow for convenient mounting and easy bleeding. View Billet Dynalite Calipers
