The R10 has a much stronger initial bite and higher coefficient of friction than the R8.
The R10 compound still maintains our smooth release, excellent modulation and rotor friendliness that have been engineered into all previous G-LOC compounds. The R10 compound leads the industry in disc/rotor friendliness . The R10 has a broad temperature range that begins at 118°F and a fade resistance is in excess of 1475°F (47°C – 801°C).
G-LOC does NOT recommended R10 for daily use on the street due to elevated levels of dust and noise.
