T#4311 - 881861999855-K - Sachs Performance Clutch Kit for JB Racing Flywheel Kit - E36, E46, Z3, Z4 - This replacement "sprung-hub" clutch package is designed to work with our (JB Racing) lightweight aluminum flywheel520-010-240 for the BMW E36, E46, Z3, and Z4 models. The Sachs HD clutch disc has a sprung hub to minimize noise and vibration and organic linings to give the feel and engagement of a stock clutch.The Sachs HD pressure plate will clamp with greater force -- allowing approximately 350 ft-lbs of torque, which makes it an obvious upgrade from the stock clutch kit.Because Sachs is an OE supplier to most German cars, replacement parts are just a phone call away. This kit uses the stock throw-out bearing (included in the price!).**Not for use with stock flywheel or other brands of lightweight flywheels** - SACHS Performance - BMW
