Description
Mantic Stage 2 Clutch Kits feature an organic / cerametallic clutch plate (OC) for improved torque capacity (over Stage 1) whilst retaining excellent driveability.
Stage 2 is the perfect balance for a serious vehicle upgrade to your daily drive.
Mantic Stage 2 Clutch Kits feature the patented ER² Groove Design CNC machined into the cover assembly pressure plate. Coupled with a 20% increase in clamp load, the torque capacity of Mantic Stage 2 kits are significantly higher than OEM specifications.
All Mantic Clutch Kits include an SG Iron pressure plate with 3x the burst strength of traditional clutch kits to ensure they can handle extreme centrifugal forces of performance applications.
The ER² 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 increases the Torque Capacity of the clutch. Torque Capacity is directly related to Rm.
