The above friction data (μ) was recorded through braking cycles from 95 mph to 40 mph at a 0.5g deceleration. Snubs were consecutively done until rotor temperature reached 1300°F. This graph represents average data and is for general trend visualisations only comparing Wilwood pads. Chart data should not be used in comparison with other manufacturer's data. Test conditions, variables, and environment can affect test results.

Temperature range and overall friction value are the primary considerations for pad selection. The pads must maintain the proper amount of friction for stopping power within the temperatures that will be realized on the track. Overall wear rate must also be considered. For most asphalt and road race applications, compounds in the high-temperature range over 1000°F 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, improved cooling, a heavier rotor, or a higher temperature range pad may become necessary.

DPC56 Caliper Calipers

DPC56 rear calipers are engineered as a high performance street and custom replacement for Corvettes and hot rods using Corvette suspension. DPC56 calipers add high-tech styling and provide the positive response and balanced pad loading provided by a fixed mount, four piston caliper. The DPC56 is a direct bolt-on replacement for the OE calipers on all models of the C5 from 1997 to 2004, and all base model C6’s from 2005 to 2013 using 12.00” diameter rear rotors. The calipers attach directly to the Corvette spindle without the need for brackets or adapters and accept all types of OE banjo bolt style brake hoses. View DPC56 Calipers
