The R6 has been specifically engineered for Autocross applications. An ultra high cold torque compound delivering consistent performance from dead cold (0°F) up to 1000°F + (0°C to 537°C+). The advanced compound matrix provides an excellent initial bite, high coefficient of friction at lower temperatures along with very progressive brake modulation and release characteristics. The R6™ compound is widely used for street use as well, but this compound will more than likely make noise on the street. G-LOC™ doesn’t recommend street driving on with R6 due to possible elevated levels of dust and noise. R6 is NOT recommended for road racing (closed circuit) use in most applications.
A high torque brake compound with a wide operating temperature range of 74°F-1250°F+ (23°C to 676°C+). G-LOC™ R8 is the first of our extensive lineup of racing compounds. Good initial bite along with excellent modulation and release characteristics. Extremely high fade resistance and very rotor friendly. Perfect for track day use with any tire and can still be driven safely to and from the track. G-LOC™ does NOT recommended R8 for daily use on the street due to elevated levels of dust and noise. G-LOC™ R8 is a popular compound for open wheel type of race cars. R8 is also used on most Formula SAE team cars, along with shifter karts, dirt bikes, ATV’s, and even Mountain bikes.
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.
Raising the bar even higher is the R12 compound with an excellent initial bite, high and consistent torque, and outstanding fade resistance over and above the R10. R12 has a temperature range of 173°F to 1860°F (78°C to 1015°C). The G-LOC™ R12 continues our excellent release and modulation that has been engineered into all previous G-LOC™ compounds. The R12 is slightly more disc/rotor aggressive than R10 but more disc/rotor friendly compared to our competition. G-LOC™ does NOT recommended R12 for daily use on the street due to elevated levels of dust and noise.
The R14 compound was engineered for endurance racing with lighter weight, lower horsepower cars in mind. R14 has solid initial bite, a little less modulation than the R10 or R12. R14 has great fade resistance with a temperature range of 210°F to 1400°F (98°C to 760°C). R14 is as rotor friendly as our R12 compound. G-LOC™ does NOT recommended R14 for daily use on the street due to elevated levels of dust and noise.
The R16 is an extremely aggressive initial bite, linear torque curve and excellent fade resistance compound from our lineup of R-Series compounds. The R16 is a natural progression of the highly successful R-Series line of compounds from G-LOC™. R16 has a temperature range of 255°F to 2000°F (123°C to 1093°C). G-LOC™ R16 maintains our philosophy of modulation and release that has been the foundation of all other G-LOC™ R-Series compounds. G-LOC™ does NOT recommended R16 for daily use on the street due to elevated levels of dust and noise and the amount of heat needed to work properly.
The R18 is the pinnacle compound of the R-Series compounds engineered by G-LOC™. R18 is based on the same successful principals and fundamentals that exist in all other G-LOC™ R-Series formulations. R18 has more initial bite, overall bite, and even more controllable torque. The R18 offers the absolute most linear torque curve we have ever created. The thermal characteristics and coefficient of friction are of the highest offered by anyone in the braking industry. This revolutionary compound will lead the way in all major forms of racing (professionally and grassroots). R18 has a temperature range of 610°F to 2100°F+ (321°C to 1149°C+). G-LOC™ does NOT recommended R18 for daily use on the street due to elevated levels of dust and noise and the amount of heat needed to work properly.
