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

Clear BMW chassis

Please ensure your correct model is selected

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.

Includes all the necessary components for a complete transmission service with Liqui Moly fluid Over the life of a vehicle, the transmission can often be overlooked when performing routine maintenance. If left unserviced, the automatic transmission fluid will break down, causing the valve body and filter to become contaminated with deposits and sludge. This will lead to poor shifting, slipping, and ultimately, transmission failure. Kit Includes: Automatic transmission oil pan with integrated filter Oil pan gasket Drain plug with sealing washer Fill plug with sealing washer 7 quarts Liqui Moly automatic transmission fluid

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.

This Febi replacement flex disc (aka: the guibo) is a vibration dampener mounted on the back of the transmission which connects to the driveshaft. When it has worn, it produces a terrible vibration throughout the car. It's especially noticeable at low speeds and when starting from a standstill. Oil leaking from the back of the transmission will significantly reduce its life. This can also be used as an upgrade on the E30 M3. It has much more rubber in between the bolt holes which makes it last longer. This is 5mm thicker than the stock E30 flex disc so adjustment of the 2-piece driveshaft may be required. The original flex disc bolts can be re-used. Applications: 1995-1999 E36 M3 manual transmission 2001-2006 E46 M3, M3 CSL manual and SMG transmission 1991-1995 E34 M5 3.6 and 3.8 manual transmission 1998-2002 Z3 M Roadster, M Coupe - S52 and S54 engine manual transmission 2006-current E85 Z4 M Roadster, E86 M Coupe manual transmission

A lightweight aluminum flywheel is a great way to increase throttle response and free up horsepower by reducing drivetrain loss. Factory flywheels are built to minimize engine and transmission vibrations, making them heavier and requiring more energy to make them spin. An aluminum flywheel can save lots of weight over the stock steel unit - sometimes over 50%. While the dampening effect of the stock flywheel is reduced, most enthusiasts would agree that the increase in performance is well worth it. In addition, the lighter flywheel allows the engine to spin more freely, improving throttle response.

This JB Racing lightweight aluminum flywheel kit and is designed to be used with the included factory clutch, making replacement and service easy and inexpensive, especially compared to specialized racing clutches. It also preserves the driveability of your car on the street, and enthusiasts tolerant of a mild to moderate NVH increase will be especially taken with this setup. In addition, the JB Racing flywheel can be easily rebuilt with a new clutch contact surface, allowing you to enjoy faster revs and superior response for many years to come.

Stock Flywheel Weight: 24-31 lbs.

JB Racing Lightweight Aluminum Flywheel: 12 lbs.

 

This item fits the following BMW Chassis:
E61/1, E82/88, E9x, Z4

Fits the follow engines:
N52 3.0L

BMW's Performance with Wheel Hub Assembly

The wheel hub assembly, often underestimated, plays a vital role in your vehicle's performance. This component connects the wheel to the chassis and incorporates metal wheel bearings responsible for wheel rotation while the car is in motion.

Over time, these assemblies can wear out and require replacement. Professional servicing can be expensive, so why not tackle this task in your own garage?

Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. 

Kit Includes:

  • Automatic transmission oil pan with integrated filter 
  • Oil pan gasket
  • Drain plug with sealing washer
  • Fill plug with sealing washer
  • 7 quarts Redline D4 automatic transmission fluid

Fits the following BMWs:

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.
