CLUTCH COVER: Specially designed clutch cover with aluminum + anodized aluminum treatment to ensure sufficient strength and durability through FEM (finite element method) analysis while being lightweight. The reliable crimping force provided by the special diaphragm spring and the nine connecting shafts coupled to the flywheel provide additional reliability.

PRESSURE PLATE: Thoroughly pursues durability and weight reduction. In order to achieve a cooling effect and segmentation of the friction surface, slits are provided on the friction surface to improve stability by making the contact uniform.

SE MECHANISM: (Smart Engage System): Used by some models, by adopting a cushioning mechanism for the pressure plate, the half-clutch area has been greatly expanded.
* The LIGHT CLUTCH does not have an SE mechanism because the clutch disc has a cushioning mechanism, but it has a sufficient half-clutch area.

CLUTCH DISC: This high-friction metal disc, developed exclusively for competition, uses a damper-type design to balance improved torque transmission without sacrificing operability. It offers excellent performance for both demanding circuit use and everyday driving on public roads.

Additionally, hub-drive carbon discs are available for select vehicle models. Leveraging carbon's unique properties—where its friction coefficient varies with temperature—these discs deliver outstanding operability and high torque transmission across a wide range of conditions.

MID PLATE: With a slit on the friction surface. The cooling effect and the segmentation of the friction surface achieve uniformity and contribute to stable torque transmission.

FLYWHEEL: Lightweight and made of chromoly steel for improved engine response. Coupled to the cover by nine connecting bolts, it distributes the load on the discs due to sudden changes in torque, suppresses deformation of each part, and improves stability.

Due to the nature of the product, the ORC clutch is designed to be "lightweight and have low inertia," so compared to stock products, the rattling noise of the transmission standby gear is more likely to be transmitted in some cases.

The noise is caused by the internal structure of the transmission, and there is no problem with the quality or performance of the clutch.
