Compound Characteristics

Compound Data Sheet
    Application:

  • High performance street / strip, drag race, and track day categories using vented iron rotors.
  • Light to medium braking on dirt tracks including late models, modifieds, sportsman, and street stocks.
  • Disc brake conversions on street rods and muscle cars.
     Characteristics:

  • Medium friction compound with the low noise and low dust of a street performance compound and the increased friction characteristics of a semi-metallic race compound.
  • Smooth engagement with consistent response from a flat torque curve throughout its entire effective temperature range.
  • Good low to middle temperature wear rates.
  • Beds quickly and provides fast response without excessive abrasion on vented iron rotors.
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.

Billet Superlite 4R Radial Mount
The Billet SL4R series adds the versatility and convenience of radial mounting to this widely popular caliper group. Radial mounting simplifies adaptation and provides two planes of adjustment for accurate alignment over the disc. The key to the superior performance of the SL4R comes from the extremely durable and efficient body design. Starting at 4.84 pounds it is the product of computer generated solid modeling and FEA stress analysis technology. Full length stiffening ribs and a reinforced radial transition from the piston bore housings to the closed end bridges has produced the strongest SL caliper bodies ever built. Continue>>>
