The flagship model of EXEDY clutches, the Hyper Carbon Series. In 1995 EXEDY supplied carbon clutch products for use in the pinnacle series of motorsport; Formula One. This same technology is now applied to carbon clutches developed by EXEDY for use on the street and track. These clutches are lightweight, durable and resilient to high heat, contributing to an improvement in track times. Available in single, twin and triple designs with both rigid or damper discs for a full range of power holding capacity.
EXEDY carbon discs are able to perform through long durations of high rotational velocity due to our precise application of carbon. The fibers are set one-by-one in a weaving pattern and baked at more than 3600°F, finalizing the strengthening process. Heat expansion rate is 1/20th of iron therefore eliminating a change in clutch feel that may happen due to distortion caused by expansion during driving. Carbon material also possesses a “non-stick” characteristic that eliminates disengagement problems.
The next generation of clutch systems by EXEDY is the Hyper Carbon-D, the revolutionary carbon clutch system. Carbon-D was developed to achieve the ultimate goal of comfort and streetability by absorbing noise and vibration emitted from drivetrain components such as the differential, transmission and engine. The Carbon-D system is designed to protect the drivetrain by absorbing and dissipating "shock torque" by utilizing EXEDY Patented Technology. Superior engineering enables the Carbon-D clutch system to posses an ideal clutch engagement position, increased clamp loads and lower pedal effort, while the unique carbon fiber friction material allows comfortable half-engaged clutch operation and responsive gear changes. The EXEDY Hyper Carbon-D is available in both single and twin clutch configurations.
The conventional damper used in a sports clutch is designed to protect the transmission from shock torque caused by abrupt clutch engagement, it does little to absorb vibration. Efficient absorption of fluctuations in engine speed requires a very flexible spring and proper setting of the hysteresis torque.*1 The Flexibility of the spring, however is likely to run counter to the damper capacity. for this reason, CARBON-D is equipped with a new damper that features two stages – a low-load stage and rapid-acceleration stage – and which is perfectly tuned for each car type. The proper adjustment of both damper rigidity and hysteresis torque prevents gear noise in the low-load stage while the new highly rigid spring ensures high-torque operation in the rapid-acceleration stage. This tuning technology is available only from EXEDY, the specialist in clutch systems.
