The AX6™ takes the place of the Panther Plus™ compound that was so successful. AX6™ was specifically engineered for Autocross applications. A high torque brake compound delivering reliable and consistent performance over a very wide operating temperature range (50°F to 1150°F +). Advanced compound matrix provides an excellent initial “bite”, high coefficient of friction, and very progressive brake modulation and release characteristics. AX6™ offers high fade resistance, rotor friendliness at all temperatures, excellent cold stopping power, and non corrosive dust. As a result, AX6™ is an excellent choice for Autocross & AX6™ has gained tremendous popularity with SCCA Prosolo/Solo2 competitors for its fantastic bite, release & modulation. 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 a race compound, and should not be used as such. AX6™ shouldn’t be used by any intermediate or advanced track day drivers, and should not be used with “R” compound tires (racing tires).
