This clutch kit is designed to replace the Original Equipment (OE) unit including the OE flywheel. This kit includes a solid steel flywheel (SMF). Designed and manufactured to replace the clutch system installed as Original Equipment, a Mantic Stage 4 replacement clutch kit offers a strong torque capacity increase. Each component has been thoroughly tested and developed for a specific application. This range provides a Quality Assured replacement part that will meet or exceed the requirements of the original unit. After 70 years of experience in developing and manufacturing clutch kits for OEM and Aftermarket use, CI is the trusted source for a complete range of Clutch Kits suited to your vehicle. MANTIC STAGE SERIES COVER ASSEMBLY: Mantic Stage 4 clutch kits feature a 20% increase (over original equipment) in clamp load for increased torque capacity. SPHEROIDAL GRAPHITE CASTINGS: Approximately 300% stronger than a standard casting this material (sometimes referred to as an Anti Burst casting) not only increases strength by up to 3 times, it also improves heat dispersion. BALANCED COVERS: To insure that the clutch system performs at maximum efficiency and that no unwanted vibration is generated as the cover spins, all Mantic Stage cover assemblies undergo a 2 stage balancing process. CERAMETALLIC FRICTION MATERIAL CLUTCH PLATE - NON CUSHIONED: The Torque Capacity of a Clutch Plate can be increased by using exotic cerametallic friction material featuring a higher coefficient of friction. However, cerametallic material reduces pedal feel and results in more sudden clutch engagement, reducing street driveability. Mantic Stage 4 Clutch Kits feature cerametallic friction material on both sides of the clutch plate, and no segment cushioning. This results in a strong torque capacity increase compared with Stage 2 and more sudden engagement compared with Stage 3 kits. This type of configuration is more suitable to rally and drift still driving; and less so for street driving. If you require a significant torque capacity increase, but still wish to drive your vehicle on the road, we recommend you purchase a Mantic Track multi plate clutch kit.This kit includes : MANTIC Heavy Duty Cover Assembly, Full Cerametallic, No Cushion (SSC) Clutch Plate For Increased Torque capacity.
