MS-1001 Mantic Street with ER² is a clutch kit specifically designed for the performance market. It features the patented groove design, ER² which is CNC machined on the friction face of the pressure plate. Capable of transmitting greater than 60% more torque than a standard clutch kit, Mantic Street with ER² is suitable for high performance vehicles. This overall torque capacity increase has been achieved by higher clamp loads, increased Mean Effective Radius of the friction area, better cooling of the pressure plate and higher coefficient of friction materials on the clutch disc. These design innovations directly equate to higher torque capacity. The clutch disc features an organic facing ring in contact with the pressure plate and a segmented cerametallic facing on the flywheel side. The cover assembly also features a decorative and corrosion resistant finish. The kit includes bearing, pressure plate, clutch disc, flywheel and bolts.
Cover Assemblies with the ER2 Groove Design feature have a unique groove pattern CNC machined on the friction face of the Pressure Plate. The groove has been specifically designed to increase the Mean Effective Radius of the pressure plate and assist in heat removal. The increase in the Mean Effective Radius of the Cover Assembly gives an increase in Torque Capacity by up to 8%. Mean Effective Radius is directly proportional to Torque capacity.
By adding the groove to the Pressure Plate, the inside radius of the friction face has effectively been increased. The first 5/16 inches of the pressure plate has all but been removed and added to this, there is progressively less material removed as the radius increases. The net effect of this is to move the effective inside radius further out. When comparing the Mean Effective Radius (Rm) of the ER2 version to the non ER2 version you can see the ER2 version is further out.
This clutch is best suited for the stock replacement on cars ranging from stock to 480 HP. Clutch kit includes:
– Pressure Plate & Clutch Disc
– Pressure Plate Bolts
– Throwout Bearing
*Take into consideration the mileage and usage of your vehicle as to whether or not you should replace your pilot bearing and slave cylinder, which is not included. We can supply you with these items if needed. We offer stock slaves, and with remote bleeders installed as well.
