Introducing the Next Generation of clutch systems by EXEDY 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.

Gear Noise and Fluctuations in Engine Rotation (rpm)
Even engines that seem to run very smoothly always have some amount of fluctuation in engine rotation. These fluctuations, when transferred from the engine to the transmission, cause gear teeth carrying no torque to strike mating teeth, resulting in noise (tooth hammer). The noise is louder in the interior as well as outside the vehicle because the clutch housing acts as a speaker and magnifies the noise. Although the noise level and noise-generating speed depend on the type and model of car, such noise is more frequent in a 6-speed vehicle than in a 5-speed vehicle

Vibration-Absorbing Damper
The conventional damper used in most sports clutches is designed to protect the transmission from shock torque caused by abrupt clutch engagement, so 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. 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 dual stage damper, a low-load stage and rapid acceleration stage, both of which are perfectly tuned for each car type. This tuning technology is available only from EXEDY, the specialist in high performance clutch systems
