87-91 Turbo Rx7 Exedy Single Disc Stage 3 Clutch Kit (ZH02SD)
Good for up to 340 ft/lb of wheel torque.
The hyper single clutch is engineered to optimize the performance of cars that are moderately modified, but do not require the clutch capacity of a multi-plate clutch. Similar to the multi plate clutches, it has a purple anodized, forged aluminum cover. 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. There is no clamp load deflection as found in a pressed metal type cover.
All Hyper Clutches come with a steel flywheel and a 6-puck disc with cerametallic facing, and a spring center damper. 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 plate 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.
