All Exedy racing and performance clutches are engineered, designed and built from the ground up as racing clutches, not rebuilt from stock clutches that have been modifed.

All of Exedy pressure plate castings are made from ductile (nodular anti-burst) iron for your safety. None of Exedy pressure plates are made of grey cast iron as are many stock pressure plates that are rebuilt in to "performance clutches". Beware, cheap grey iron rebuilt pressure plate castings may explode, unlike nodular iron.

Exedy Racing clutches with organic friction materials use only premium friction materials that are resistant to slippage and burst. Increased clamp loads give the necessary capacity to handle modifed engines. Organic friction material clutch is the preferred clutch for street and light horse power track.

The driveability will be like a stock clutch. Pedal efforts will be slightly higher because of the higher clamp loads. All of Exedy clutch discs have high capacity spring center dampers to reduce the drive train shock and impact.

Exedy cerametallic clutches are designed to handle the abuse of high power modified engines. Cerametallic friction maerial can handle much more slippage that stock type disc assemblies without slipping and fading. All Exedy cerametallic discs have spring center dampers to reduce the impact and shock loads put into the drivetrain. This protects the transmission and the rest of the drive line system.

With any cerametallic clutch system, there will be some compromise of start up driveability as compared to a stock clutch (chatter on light throttle, low rpm start up). This characteristic is generally felt to be acceptable in modified performance cars.

All Hyper Single Clutches come with lightweight steel flywheel and a 6-puck cerametallic facing, spring center damper disc 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 synchroes. 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.

As with all cerametallic clutches, the street drivability may be marginal due to chattering and harsh engagement characteristics. Approximate HP capacity is up to 550HP.

For high-powered applications, Exedy offers twin and triple Multi-Plate Clutches. These are designed for hot street action as well as drag, road, and rally racing.

The Twin-Plate clutches are rated for above 500hp to 705hp. The Triple-Plate clutches are rated for up to and over 1000hp (for drag race applications). Twins come with both spring damper discs (SD type) and solid discs (SR type). Triples are all solid discs.

All multi-plate clutches come with a lightweight, chromoly steel flywheel and the famous puple anodized forged aluminum clutch cover.
