Stage Four
We recommend these clutches for serious drag/road racing purposes since they engage instantaneously and are not comfortable for every day driving. The kit comes with a high clamp pressure plate, 3, 4 or 6 puck carbon semi-metallic rigid 2-piece clutch disc with high torque rigid hub and carrier assembly with install tool. This applicaiton does not utilize a conventional throwout bearing, as the releaser is a concentric hydraulic slave/bearing assembly. This concentric slave is available as an option to the kit. Leave us a note when you checkout to tell us your choice of 3, 4 or 6 puck configuration.
This clutch kit is designed for use with the factory flywheel or an aftermarket flywheel modeled after the factory wheel, which has a recessed friction surface. For SPEC non-ratcheting clutch and flat flywheel packages, see kit numbers SC661-SC665. These kits increase friction surface diameter to 12 inches while reducing rotating mass by up to 36%. The flywheel package includes race bolt kit.
SPEC Stage 4 Clutch Kit:
This unit is a solid hub version of the stage 3. The hub is solid 8-rivet and the assembly is heat treated for strength and durability. It is available in a 3, 4 or 6 puck configuration. Use the 3 puck for the lightest option or the 6 puck for the smoothest engagement. The 4 puck is a good compromise for both. Street drivable in 6 puck configuration, but not street friendly due to the rigid hub.
Types of Driving:
Drag, Road Racing, Pulling, Rally, Drift
