BMW Drivetrain Parts for BMW Z4 M Roadster S54 (2003-2008)

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

Unlike other aftermarket mounts, the mounting plate and studs of our mounts have been Zinc-plated to prevent corrosion. Rogue Engineering Transmission Mounts are sold as a pair, and come with Grade 8 Zinc plated hardware. Rogue Engineering transmission mounts are designed with street comfort in mind while still reducing left and right movement of the transmission. By using a cylindrical shape instead of the factory hourglass like design and utilizing Neoprene rubber deflection can be significantly reduced, minimizing unwanted transmission movement while maintaining vibration dampening characteristics.

The stock center support bearing carrier is designed to reduce NVH to the cabin by loosely holding the center bearing with a flimsy rubber bushing. During launches and shifts, the driveshaft is allowed to travel off-center, decreasing throttle response and causing oscillations through the drivetrain. As they age, the carrier rubber sags and dry rots, ruining the driveshaft alignment. Fix or prevent this common issue with JXB Performance's Driveshaft Center Support Bearing Upgrade! JXB utilizes a simple but extremely effective 2-piece design which allows you to install this upgrade and replace bushings with ease. The stock center support carrier is simply cut away, allowing the JXB bushings to "clamp" down on the driveshaft bearing and hold the driveshaft securely in place, maintaining driveshaft alignment at all times. Two bushing options are available for this kit, Street and Track, both of which are many times better than the stock bushings: The street bushings absorb most of the NVH from the drivetrain. Some light NVH is possible at some speeds in the form of a soft hum. (With a modified exhaust or windows down, you’ll probably never hear it) The track bushings are for those who want no-compromise drivetrain performance. These may create a substantial amount of cabin noise. Not sure which is for you? Try them both, they’re interchangeable! Installation does not require the removal of the driveshaft. The 2-part design clamps around the OEM bearing. The old carrier must be removed, so a cutting tool is required. Looking for replacement or additional bushings? See T#4799658 for replacement street bushings and T#4799659 for replacement track bushings.

This lightweight aluminum flywheel w/ Heavy Duty "sprung-hub" clutch package is the best-engineered solution for E46 325 and 330 models with the 6-speed transmission, Z4 2.5/3.0, and Z4 M Roadster and M Coupe. 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 sport sprung-hub clutch with the correct pressure plate and combined it with their 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).
