Exedy Racing Stage 4 Hyper Twin Organic Clutch Kit: 2004-2017 Subaru WRX STi

For high-powered applications, Exedy offers twin and triple Multi-Plate clutches. These are designed for high power street action as well as drag, road and rally racing. The twin plate clutches are rated for approximately 500 ft/lbs of torque and the triple plates are rated for approximately 800 ft/lbs of torque, both figures at the flywheel. Twins come with both spring damper discs or solid discs depending on application, whereas triples are all solid discs and not recommended for street use.

All Exedy Hyper Multi-Plate clutches come with a lightweight, chromoly steel flywheel and the famous purple anodized forged aluminum clutch cover. Depending on the application, they have both strap drive and lug drive models. All have T5001 cerametallic friction materials for extreme heat resistance. Surprisingly, even with its additional power capability, most multi-plate clutches exhibit light pedal pressure thanks to a half-engaged “zone” provided by the patented clutch “cushion” function.

All EXEDY Racing Hyper Multi Series Clutch Kits carry SFI 1.2/1.5 Certification.
