Race Technologies Racing Brake Pads RT RE10 COMPOUND1 RE10 is the ultimate endurance race compound, offering a balance of excellent stopping power, low thermal conductivity, and extremely low pad and rotor wear. Utilizing the latest friction material technology, Race Technologies RE10 offers consistent performance in the most demanding environments. Typical applications include professional endurance racing, club racing, and HPDE on high braking demand platforms. RACING PAD NOTES: Running a "racing use only" pad on the street could produce excessive noise and dust. Rotor wear could be accelerated if driven at consistently cold temperatures or used in the incorrect temperature range. Racing pads are designed to work in specific temperature ranges so it's important to choose the right compound for the environment the vehicle will be used in. Pad compounds are tested on a brake dynamometer over repeated brake applications to test the materials in a controlled environment. Real-world wear rates and temperatures will be influenced by car setup, grip levels, track layout and other variables. Note 1: "RE" denotes a "racing use only" pad compound.
