Spec Stage 4 Clutch Disc and Pressure Plate kit; 911 3.6L, Boxster S

Spec Stage 4 clutches are basically a solid hub version of the Stage 3 clutch. 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. Best for drag racing, road racing, pulling, rallye and drift._x000B__x000B_Torque Capacity: 508ft/lbs_x000B__x000B_The Spec Stage 4 clutch is a built-to-order item; please indicate 3, 4, or 6 puck when ordering.
