Compound Data Sheet
Application:

  • Most dirt track applications including super late models, modifieds, and rear inboard sprints using vented iron rotors.
  • Light to medium duty road racing and track day events.
  • Drag racing with iron or steel rotors.
  • Performance street category competition.
Characteristics:

  • Consistent, linear response through temperature range.
  • Baseline for light to intermediate dirt applications with vented iron rotors.
  • Drag racing with steel rotors.
  • Auto-cross and lighter duty road racing.
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.

WLD-20 Caliper

WLD-20 racing calipers provide the ultimate in strength, weight savings, and high efficiency brake clamping for F/F and all other formula category road race vehicles configured for use with the traditional LD20 lug mount style calipers. The calipers feature a high strength, light-weight 2.3 pound forged aluminum body fitted with machined stainless steel pistons in the standard WLD20 model, or heat-blocking Thermlock® pistons in the WLD20/ST models. All WDL20 series calipers utilize the same mounting centers, height and offset as the traditional LD20 calipers. The calipers accept WIlwood type 5214 brake pads, or any brake pad made to fit the original LD20 models. View WLD-20 Calipers
