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.

XRZ4R Radial Mount Calipers

Wilwood’s next-generation XRZero race calipers combine decades of race experience, computer finite element analysis (FEA), and state-of-the-art machining into a race caliper that is lighter and stiffer, with zero drag. The unique shape of the high surface area body creates a caliper with superior brake fluid cooling and allows more airflow through the rotor. Optimized profile high-temperature seals provide better piston retraction resulting in less drag. The unique center X-bridge strengthens the caliper body without adding mass or obstructing airflow to the brake rotor or pads. Computer FEA design and precision CNC machining of the stress-flow forged aluminum body results in a caliper weighing just 4.66 pounds - 1/2 pound less than a comparable sized Wilwood Superlite caliper.
