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

This is an OEM LuK stock twin mass flywheel for the N52 non-turbo engine in the 128i, 325i/328i/330i, 525i/528i/530i, and Z4 30i. It's manufactured by OEM supplier LuK. Sachs recommends a new dual mass flywheel (DMF) on every other clutch replacement. There are several indicators for replacing the flywheel: damage to the clutch contact plate (from a severely worn clutch disc), grease leaking from inside (overheating), build-up of clutch material on the contact plate (excessive slipping and overheating), and failure of the internal damping system.

The dampening system uses rubber or coil springs to absorb driveline vibrations. Through age, excessive heat, and aggressive use the rubber loses its resilience and the metal springs lose their strength and become brittle. If the clutch and flywheel have become overheated the internal grease may break down as well. A DMF failure can be massive and catastrophic, not to mention dangerous as bits of metal and rubber fling themselves through the transmission bellhousing. Heat and aggressive driving will accelerate the wear so race and track cars should have their stock flywheels replaced at regular intervals or with any new clutch. Even normal street cars should plan for a new flywheel if it has high mileage.

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components. 

Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

This kit from Valeo is a simple way to easily convert your stock dual mass flywheel clutch system to a single mass system.

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. Why convert from a dual-mass flywheel to a single-mass flywheel?

Cost: Dual-mass flywheels are expensive, with the cost of replacement often times being double or triple than that of converting to a single-mass flywheel.
Serviceability: Single-mass flywheels can be resurfaced, eliminating the need to replace 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 application.
Simplicity: 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.
Pedal Feel: Many enthusiasts prefer to eliminate BMW's "Self Adjusting Clutch", which has been known to provide an unpredictable, inconsistent engagement point.
Driveability: 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.
