BMW Drivetrain Parts for BMW Z Series E85/6 (2003-2008)

Clear BMW chassis

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.

Designed with 100% comfort and low manufacturing costs in mind, BMW's factory carrier bushing offers a freedom of movement on all axis, resulting in "factory installed slop".

The wheel hub is a generally overlooked part of your vehicle, but they are crucial to optimum performance. The assembly links the wheel to the chassis and is equipped with metal wheel bearings that turn the wheel as the car moves along. Over time, these assemblies can become warn and in need of replacement. Yet, paying a professional to do the job will cost an arm and a leg, so why pay someone else to do it when you can in your own garage?

These rubber bushings from Meyle are a direct replacement for the stock differential bushings in the E46 3-series, E83 X3 SAV, and Z4 Roadster. If your original bushings are worn (likely around 100,000 miles) these are a great replacement upgrade. The front bushings are the stock OEM type rubber bushings. The rear bushing is a Meyle HD upgrade over stock - about 15% stiffer than the originals. This means the bushing will not flex and twist as much. This puts more power to the wheels since power is no longer used up for 'torquing' the bushing. These are not race bushings; the rubber material is perfectly suitable for street use.

The non-M E46/E83/Z4 models use three differential mounts - two front bushings in the subframe and one rear mount in the diff cover. This set of bushings covers all three. You can opt to include new mounting hardware in the Options list below.

This item fits the following BMWs:
1999-2005 E46 BMW 323i 323ci 325i 325ci 325xi 328i 328ci 330i 330ci 330xi

Dual-mass flywheels allow for fluid-feeling clutch engagements and offer a more luxurious feel than single-mass flywheels. However, with these benefits come significant drawbacks. Dual-mass flywheels are expensive, with the cost of replacement often being double or triple that of converting to a single-mass flywheel. Single-mass flywheels can be resurfaced, eliminating the need to replace them with the next clutch service, something that is not recommended with dual-mass flywheels as they contain a rubber section that is more failure-prone in high-mileage applications. Single-mass flywheels lack the complexity of dual-mass flywheels, making them inherently more reliable. Dual-mass flywheels contain a rubber damper or hub that will, like all rubber components, wear out with time. Also, Many enthusiasts prefer to eliminate BMW's "Self Adjusting Clutch", which has been known to provide an unpredictable, inconsistent engagement point. Valeo's conversion kit has been designed to maintain nearly identical clutch and flywheel weight, ideal for keeping the clutch quiet and easy to drive. Kit contents: Single-mass flywheel Non-Self Adjusting Clutch and pressure plate Throw out bearing Pressure plate bolts Flywheel bolts Transmission service kit Guide tube Input and output shaft seals Pilot bearing Clutch fork pivot pin Mounting bolt set

Located between the transmission and driveshaft, the giubo (also giubo) joint is a flexible rubber drive coupling that joins driveline components to reduce vibration, while allowing a limited range of flexibility. Joint rubber deteriorates over time from torque stress and heat hardening. A failed joint is a common cause of driveline noise and vibration. This kit includes a new drive shaft center mount with bearing to insure proper driveshaft placement. Includes Driveshaft center support bearing (csb) Driveshaft front flex disc (giubo) installation hardware for flex disc and center support bearing Driveshaft centering bearing Butyl tape for center support bearing insulation
