Furthermore, the Centerforce Dual Friction disc has a full facing on the pressure plate side for drivability and longevity, while a carbon composite puc-style (segmented) facing is used on the flywheel side for a positive engagement and increased holding-capacity. The Dual Friction clutch is engineered for those who are looking for the ultimate in street/strip holding power and performance without sacrificing pedal effort and driver control. While the Dual Friction has been engineered primarily as a street clutch it can be used in mild competition applications.The Centerforce Dual Friction(R) Clutch Series uses patented technologies for an ultimate pressure plate and disc combination.
