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 Calipers

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

D52-R Single Piston Floater Calipers

Wilwood's newest pure heavy-duty race caliper, the D52-R starts with a lightweight 4.3-pound forged aluminum Type III hard anodized body with a stainless steel piston. Choose a width of 2.75” or 2.38” pistons, and rotor widths of 0.81”, 1.04” and 1.28" thick in common 11.75”, or 12.19”, and up to 12.50” diameters. Caliper fluid inlet port centered directly behind the piston eliminates any interference with slide pins. Lower deflection rate and higher volumetric efficiency than all the competitions’ heavier cast models, D52-R calipers also use standard D52 pads available in a range of compounds for every application. Caliper mounting uses the original GM stock height and offset. D52-R Caliper, also known as D52R Caliper, is the pinnacle design for OEM replacement racing calipers.
