CP3921

AP Racings' Cerametallic range of competition clutches have been designed to handle demanding situations where a degree of clutch slip is required, mostly for rally use. The cerametallic plates are resistant to high energy inputs (i.e. long slip), as well as having a smoother engagement, allowing for better control and feel at the pedal. Due to the unique compound mixture of ceramic and metallic materials, the drive plates benefit from low wear rates, both reducing dust and debris build up. Each clutch component is individually tested at the factory prior to shipping to ensure that the part is of the highest quality.

There is a wide range of torque ratings and drive plate types available to suit most applications ranging from Formula 3 to Rallying and Endurance Racing. Although primarily used in rally applications, cerametallic clutches can also be used for circuit racing. Drawing on their years of top level experience, the knowledge that has been attained has been used to continually improve and polish the whole range of clutches in order to keep up with the ever demanding motorsport environment. The result is a huge selection of the finest quality racing clutches which can be available for all forms of motorsport, while making use of the latest in clutch technology.
