The Carbotech™ AX6™ brake compound is specifically engineered for Autocross applications. A high torque brake compound delivering reliable and consistent performance over a very wide operating temperature range of 50°F to 1100°F + (10°C to 593°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. AX6™ offers high fade resistance, rotor friendliness at all temperatures and excellent cold stopping power. As a result, AX6™ is an excellent choice for Autocross and has gained tremendous popularity with SCCA Prosolo/Solo2 competitors for its outstanding all around performance. Many drivers use the AX6™ for street driving as well, even though Carbotech™ doesn't recommend street driving with AX6™ due to possible elevated levels of dust and noise. AX6™ is NOT recommended as race compounds in most applications
