Z3 JB Racing Lightweight Flywheels
has
manufactured and supplied high quality lightweight aluminum flywheels to the

manufacturer of the BMW E36 aluminum flywheel. JB Racing is constantly expanding
their flywheel line to include the latest performance applications such as; Mini
Cooper and BMW E46 325/330, and Z4 utilizing the new 6-speed (SMG) transmission.
ALL of the current dual-mass replacement flywheels are designed to accommodate
most of the common sprung-hub clutch discs to minimize the gearbox “rattle.”
Sachs, S.P.E.C., Clutch Net, and others manufacture sprung-hub discs that will
clear in the center hub cavity of these flywheels.
All of their flywheels are designed, manufactured, and assembled in-house at
their Florida facility which allows to maintain stringent quality control.

E36, E46, Z3, Z4 HD Clutch and Flywheel Kit
(more info)
This lightweight aluminum flywheel w/ Heavy Duty "sprung-hub" clutch package is the best-engineered solution for the BMW E36, E46, Z3, and Z4 models. Instead of picking a clutch from another car that may or may not work at all, the engineers at JB Racing have taken all of the guess work out of this upgrade and incorporated a Sachs HD sprung hub clutch with the correct pressure plate and combined it with our most-popular aluminum lightweight flywheel. 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. Mixing and matching of the incorrect clutch, pressure plate, and flywheel components can lead to inconsistent engagement and feel -- why make your clutch feel worse?
In addition, 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. And with the aluminum flywheel weight savings is substantial over the stock dual-mass flywheel - which allows your motor to spool up faster and transmit more HP to the ground.
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!).
