BMW Drivetrain Parts for BMW E34 M5 S38 3.5L

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.

Aluminum flywheels are much lighter than the stock steel flywheel and that produces better throttle response and more available horsepower to the wheels for faster acceleration. The JB Racing aluminum flywheels are a direct replacement for the stock flywheel and work with stock clutch components for an easy upgrade with very little downside.

Modern flywheels are built with additional components and features that are designed to dampen and minimize vibrations from the engine and transmission. As a result they have become bloated in weight and that means more energy is used up just making the flywheel spin. The weight difference between an aluminum and steel flywheel is huge - sometimes more than 50% less. Without the additional mass, more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance.

In addition to releasing more power to the wheels, the lighter flywheel allows the engine to spin more freely, which improves throttle response. Again, the difference is huge as you watch the revs build faster than before. With the engine spinning easier the power band comes up much sooner. The stock steel flywheel feels lazy in comparison. There is a driving adjustment required to get used to how much faster the engine revs but that's not really a downside.

The JB lightweight flywheel is designed to be used with a factory organic clutch - the same clutch kit that you would get from any BMW dealer. This makes replacement clutch components easy to source and inexpensive when compared to specialized racing clutches. By using the factory BMW clutch, JB has also made the whole assembly easy to live with when used on the street. The clutch behaves the same as it originally did - just with better throttle response and more power! The JB flywheel can also be rebuilt with a new clutch contact surface - you don't have to buy a new flywheel.

Aluminum flywheels are considered 'single-mass' flywheels because they do not have the same dampening designs as an original 'dual-mass' flywheel. With a single-mass design more noise and vibration may be noticeable.

Stock Flywheel Weight = 16.0lbs
JB Flywheel Weight = 8.0lbs

BMW Shifter Carrier Arm Bushings - Round are essential for enhancing shifting precision and feel in your BMW’s manual transmission. These 90A urethane bushings from Turner Motorsport replace the stock rubber bushings, which tend to wear out quickly, resulting in sloppy shifting.

This upgrade is perfect for enthusiasts seeking a more responsive shifting experience.

These bushings are compatible with various BMW models, including the E30, E36, E46, E28, E34, E39, E24, and Z1 Roadster, and serve as a direct replacement for BMW part #25117519669. Installation is simple when the shifter carrier is removed from the vehicle.

These are the stock rubber motor mounts. When motor mounts begin to wear the engine can shift and contact other things in the engine compartment, mostly cooling-related parts. This is especially troublesome on older models. Don't neglect your motor mounts! A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).

The Powerflex Rear Diff Front Mount Bushing (Race) for BMW E34 5 Series and E32 7 Series is a premium upgrade designed for enhanced drivetrain stability and performance. Here’s another description:

  • Race-Grade Polyurethane: Part of Powerflex’s Race Series, this bushing is crafted from a super-stiff polyurethane compound, designed to eliminate the excessive movement found in factory rubber bushings. The Race Series is optimized for track and high-performance driving, where minimizing flex is crucial for precision handling.

  • Purpose: This bushing replaces the front mount of the rear differential, a critical point where unwanted flex can reduce performance. By stiffening this mount, the bushing ensures improved power transfer to the wheels and reduces drivetrain slop, making the car feel more connected and responsive.

  • Key Features:

    • High Durability: Polyurethane in the Race Series is resistant to wear, oil, and contaminants, offering longevity far superior to rubber bushings, especially in harsh driving conditions.
    • Maximized Control: The stiffer material prevents the differential from moving excessively under load, providing more consistent traction and improved rear-end stability.
    • Straightforward Installation: This bushing is a direct replacement for the stock component, making it easy to fit and offering immediate performance benefits without extensive modifications.
  • Benefits:

    1. Enhanced Power Delivery: By limiting differential movement, the car experiences less drivetrain lash and more precise power delivery, which is especially noticeable during hard acceleration and cornering.
    2. Reduced Differential Flex: The reduction in flex at the diff mount allows for improved handling and cornering response, making the car more predictable and stable at higher speeds.
    3. Track and Performance Ready: The Race Series bushing is designed for drivers who demand the best from their vehicles, especially in motorsport settings where precision and durability are key.
  • Fitment: Tailored specifically for the BMW E34 (5 Series) and E32 (7 Series) models, this bushing replaces the front differential mount and offers a perfect fit, ensuring no compromises on installation or function.

In summary, the Powerflex Rear Diff Front Mount Bushing (Race Series) is an essential upgrade for BMW E34 and E32 owners looking for improved drivetrain rigidity, better handling, and longer-lasting components. Perfect for performance enthusiasts and track-goers, it enhances rear suspension control and reduces drivetrain movement for sharper, more precise driving experiences.
