Compound Data Sheet
Application:

  • Race ONLY compound for long wear in sustained high heat on hard braking ovals and road courses.
  • Trail braking or "touch and go" tracks.
  • Endurance applications.
Characteristics:

  • Smooth initial engagement with a linear increase as heat and pressure rise.
  • Severe duty use for road courses and hard braking pavement/dirt ovals.
  • Predictable response with excellent modulation at all temperatures.
  • Long wear rate for durability in sustained high heat.
  • Compatible with all iron and steel rotors.
  • High torque on SS 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.

D52 Dual Piston Floater Caliper

The D52 caliper is a direct bolt-on 2 piston replacement for the factory original single calipers on many 1968-96 GM Passenger Vehicles and Trucks. Forged billet aluminum bodies, stainless steel pistons, and competition style high-temperature seals put and end to the rust, bore pitting, and seal failures that plague the OE caliper design. D52 calipers provide low-maintenance performance and a huge weight savings with high temperature reliability for the street and track. View GM D52 Dual Piston Calipers

GM III Single Piston Floater Caliper

Wilwood’s GMIII caliper represents the latest refinements in caliper design and manufacturing through solid modeling and stress simulation programs. The result is the most rigid, highest torque, lightweight aluminum caliper with weights starting at 3.36 pounds. Requires use of hardened Wilwood slide pins (sold separately), request part no. 230-0619 (slide pin kit) contains 4 slide pins, enough for two calipers View GM Single Piston Calipers
