Why ORC

ORC has an extensive history of providing clutch applications for the most competitive series. From D1GP to Super Taikyu, All Japan GT Championship, and numerous other racing series, top competitors use ORC for their clutch needs.

With a lightweight chromoly flywheel manufactured with FEM (finite element method) analysis, rotational mass is reduced for improved engine response. The flywheel is coupled with the precision machined aluminum pressure plate via nine connecting shafts to disperse torque loads from high stress racing situations, and specially designed diaphragm springs allow consistent and reliable clamping force.

The optimal combination of the clutch cover diaphragm springs and high friction, low wear metal-based discs provides ORC clutch kits with high transmission torque capacity with a small disc diameter (as small as 137mm) for improved engine response.

Some clutch discs have a spring mechanism built in to reduce drivetrain shock and chatter when the clutch engages, so the driver can enjoy a smooth driving experience.

ORC Carbon clutches feature a hub drive to improve the engagement and feel of carbon clutch discs, which has a coefficient of friction that changes with temperature.
