2017-2020 Subaru STI Exedy Hyper Twin Series Cerametallic Clutch and Flywheel Kit HR

Hyper Twin Series Cerametallic Clutch and Flywheel Kit

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, we have both strap drive and lug drive models. All have T5001 cerametallic friction materials for extreme heat resistance. Surprisingly, even with it's additional power capability, most multi-plate clutches exhibit light pedal pressure thanks to a half-engaged "zone" provided by the patented clutch "cushion" function.

SD/HD Type

This model has been developed for high powered street cars and race cars with up to approximately 600TQ @ FW. They feature ventilated, thick intermediate plates for improved life and spring damper discs to protect your transmission and drive line. "HD" kits have slightly high clamp load than their "SD" counterparts and have approximately 20% higher power capacity.

SR Type

These clutch covers are designed to achieve a clamping load that is approx. 40% higher than the genuine part allowing a higher torque transmitting capacity. Ductile material is used for all pressure plates and, high burst strength can be achieved in all temperature ranges.

HR Type

This model has three plates and is developed specifically for high power applications such as over 800 ft/lbs of torque at the flywheel for drag racing. It handles high torque loads and shifts smooth, and because of the lightweight clutch discs, you can reduce your shift times.

EXEDY Lightweight Flywheel

EXEDY Lightweight Flywheels combine low weight, low inertia and high thermal capacity. They are designed for light to moderately tuned racing cars for drag racing, autocross and rally events, as well as street usage. They are made from solid one-piece billet chromoly steel or chromoly steel forgings. They are specifically designed to reduce weight and inertia for better engine response. Most incorporate special design features to enhance the airflow which improves the cooling of the clutch.The ring gear teeth are integrated onto the flywheel unlike an aluminum flywheel where the ring gear is pressed onto the flywheel and has the possibility of separating from the flywheel due to the different expansion coefficients of aluminum and steel. Newly available are lightweight, solid replacements for vehicles fitted with OE dual mass flywheels. EXEDY lightweight flywheels have passed engineering tests to 15,000-18,000 RPM. They are guaranteed not to fail to the said RPM, and are all SFI approved.
