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.
