PolyMatrix A Friction Coefficient and Temperature Values PolyMatrix A Friction Coefficient and Temperature Values Zoom Image

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.

Billet Narrow Superlite 4-Race Calipers

The Superlite caliper series once again has a cutting-edge performer in the new differential piston bore version. Differential piston bores compensate for leading-edge mechanical loading and temperature variance across the pad face to reduce pad taper wear in sustained high temperature applications. Thermlock® pistons in the FSL4/ST and heavy wall stainless steel pistons in the FSL4 models provide choices for two levels of protection against conductive heat transfer to the seals, fluid, and caliper body. Both the FSL4 and FSL4/ST start at just 4.40 pounds. View Billet Narrow Superlite 4R Radial Mount Calipers

SLC56 Caliper Calipers

SLC56 front calipers are engineered as a high performance street and custom replacement for Corvettes and hot rods using Corvette suspension. SLC56 calipers add high-tech styling and provide the positive response and balanced pad loading provided by a fixed mount, four piston caliper. The SLC56 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 12.8” diameter front 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 SLC56 Calipers
