By adopting lightweight and ultra-high-strength fibers that are also used in body armor (bulletproof clothing), we have increased the heat resistance of other raw materials and the combination of materials. We have succeeded in reducing weight while ensuring wear resistance and friction characteristics.

Improved wear resistance in ultra-high temperature range

The use of high-strength fibers has made it possible to use highly heat-resistant materials that were previously difficult to use. Compared to conventional materials, it suppresses the increase in wear even in the ultra-high temperature range, which is one rank higher.

Ensures a high coefficient of friction over the entire temperature range

Achieves a high friction coefficient that overwhelms conventional facings from the normal use range of 100℃ to the ultra-high temperature range. Demonstrating torque capacity one rank higher, it is unrivaled.

Enhanced Low Inertia Design

This design integrates a high-rigidity aluminum alloy for the clutch cover with a lightweight flywheel, achieving a 30% reduction in overall kit inertia compared to the original equipment (OEM) clutch and flywheel assembly. Such a configuration enhances engine responsiveness while maintaining smooth vehicle start operability.

Furthermore, the inertia of the clutch disc has been significantly reduced by 29% through two key modifications: the reduction in the clutch disc’s diameter and the utilization of lighter friction materials. (compare to genuine clutch disc, in case of CT9A)

Optimized Pedal Effort

To minimize pedal effort, a novel diaphragm spring has been implemented(PUSH Type Cover). This innovation, coupled with the integration of cushioning plates for manageable half-engagements and a high-rigidity aluminum alloy clutch cover, ensures superior clutch performance across various environments, from daily street driving to competitive circuit racing.

Advanced Silent Damper Technology

Gear noise occurs when engine rotation fluctuations are transmitted to the transmission. Soft springs on the silent damper absorb the rotational irregularities at the idling stage.
