The emergence of heavier and more powerful vehicles has led to the development of the ultimate semi-metallic, street compound with impressive pedal feel and the lowest levels of disc rotor abrasion, noise, and dust levels amongst the CC line-up. Perfect within the street temperature and speed range with a high level of braking force and controllability. Ceramic Carbon Metal Series Driving Field : Street Recommended Tire Use : Radial Tires Appropriate Rotor Temperature : 120-900 Degrees F Average Coefficient of Friction : 0.38 - 0.45
