The Hyper Single Clutch is engineered to optimize performance for cars that are moderately modified, but do not require the clutch capacity of a multi-plate clutch. Similar to Exedy's multi-plate clutches, it has forged aluminum cover that is anodized purple. The aluminum cover is stiffer than a stamped cover and therefore allows a higher lever ratio to maintain the pedal efforts at a reasonable level. No clamp load deflection as in a pressed metal type cover. All Hyper Clutches come with a steel flywheel and a 6-puck ceramerallic facing, spring center damper dis assembly. The disc is generally smaller and thinner than the OEM disc making for lower inertia and therefore quicker, easier shifting and less wear and tear on the transmission synchros. The higher clamp load and cerametallic friction facings give approximately twice the holding torque of the OEM clutch and generally higher than other single pleate clutches. An additional feature of the pressure plate is a series of turbine-like, air flow enhancing vanes that keep the clutch cooler under extreme operating conditions to improve wear life. As with all cermetallic clutches, the street drivability may be marginal due to chattering and harsh engagement characteristics.
