Exedy Stage 3 Hyper Single Metallic Disc Clutch Kit STI 04-12 EJ20 Shortblocks 6% difference in flow betweenAll 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. 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.
