BMW Drivetrain Parts

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.

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.

NOTE: We suggest replacing 3 of BMW # 31126760203 during installation Kit comes supplied with M14 mounting bolt, thread locker, and a Powerflex keyring. With the newer F8x M2/M3/M4's making big power and having superb chassis straight from the showroom, it's no wonder they're often found at the most serious of track-days or at tuning shops around the globe. Unfortunately, the power that makes these cars so fun to drive eventually has an impact on the vehicles' suspension components- most notably the rear differential bushings. Despite having alloted for two mounting bushings on the factory tubular subframe, BMW opts to use only a single offset bushing in the rear to mount the diff bracket to the subframe. This essentially creates a pivot point for the diff under torque loading, especially if the 4x front diff bushes are worn out and softer than they once were. With hard launches and sudden and frequent on-off throttle changes, the single rear OE rubber bushing is subject to extreme torsional and directional forces, resulting in rapid degradation with failure often seen at around the 30,000-40,000 mile mark, and an unsettled and potentially clunky rear-end. The PFR5-4030 Dual Mount Diff Bracket is made from our in-house CNC machined 6082 High-Tensile Aluminum, and is designed to utilize the secondary mounting position on the OE subframe. With the addition of a second bushing, this prevents the diff from twisting under load, providing benefits such as: Reduced drivetrain movement Improved throttle response A more controlled and consistent chassis response to acceleration/deceleration Improved tire-to-road power transfer due to reduced wheel hop Reduced strain on bushings The corrosion-resistant, satin black, anodized aluminum bracket is optimized for high stress and deflection while withstanding high torque loads, but serves the same purpose in road-use and track-use cars with either a single OE bushing or dual aftermarket bushings. Although the bracket can be fitted without the need to remove the subframe from the vehicle completely, we would strongly recommend combining Powerflex products by using our already hugely popular 80A durometer PFR5-4026 Rear Diff Rear Mounting Bushings for both rear mounting positions alongside our PFR5-4025 Rear Diff Front Mounting Bushings in the front for the ultimate in differential control and a lasting street or track solution.

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. 

Engineered to perform, Powerflex performance polyurethane differential 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.

The Powerflex Rear Diff Front Mount Bushing for the BMW E46 3 Series and Z4 is a premium upgrade designed to enhance the stability and performance of the drivetrain. Here’s an alternative description:

  • High-Performance Polyurethane: Powerflex bushings are made from advanced polyurethane, which is significantly more durable than standard rubber. This material resists wear, deformation, and the effects of heat, oil, and contaminants, making it a long-lasting solution for high-performance applications.

  • Purpose: The rear differential front mount is subjected to high levels of stress during acceleration and cornering. Over time, the stock rubber bushing can degrade, causing excessive movement in the differential. The Powerflex bushing eliminates this movement, allowing for improved drivetrain control and reducing unwanted flex.

  • Key Features:

    • Enhanced Rigidity: By replacing the softer OEM rubber with Powerflex’s stiffer polyurethane, this bushing minimizes differential movement under load, resulting in improved throttle response and sharper handling.
    • Improved Longevity: Unlike the factory rubber mounts, which can crack and wear out over time, the polyurethane construction ensures long-lasting performance and reliability.
    • Performance-Oriented Design: Powerflex’s bushing is engineered to handle the increased demands of spirited driving and track use, offering better control without sacrificing comfort.
  • Benefits:

    1. Improved Power Transfer: Reducing differential movement helps direct more power to the wheels, improving acceleration and delivering a more connected driving feel.

The Powerflex Heritage Rear Differential Mount for the BMW E46 M3, available through outlets like Turner Motorsport, is an ideal upgrade for enthusiasts seeking to enhance the performance and durability of their car's rear differential while preserving its classic appearance. The Heritage Series is tailored for those who prefer a more subtle aesthetic than the brightly colored bushings typical of Powerflex's standard line.

Key features:

  • Heritage Polyurethane Composition: The bushings are made from high-performance polyurethane, providing superior resistance to wear, cracking, and degradation compared to the original rubber mounts. This helps improve handling without compromising ride comfort.
  • Classic Appearance: Unlike the regular Powerflex bushings, which come in bright colors (yellow or purple), the Heritage Series bushings are finished in a muted dark green/black, allowing them to blend seamlessly into the undercarriage of the vehicle, ideal for those who prefer a more OEM look.
  • Enhanced Handling and Stability: The rear diff mount works to reduce the unwanted movement of the differential, which translates to improved traction, better throttle response, and more consistent handling in high-load scenarios like hard cornering or acceleration. This significantly reduces wheel hop and enhances rear-end stability.
  • Direct Fitment: These mounts are designed to be a direct replacement for the factory bushings, requiring no additional modifications. This makes them an excellent choice for both DIY and professional installs.
  • Perfect for Street and Track Use: Combining durability and flexibility, this mount is suitable for E46 M3s that see a mix of daily driving and occasional track use, offering the best of both worlds by improving responsiveness while maintaining comfort.

Turner Motorsport often emphasizes the balance of performance and OEM-like comfort with these mounts, making them an excellent choice for those wanting to upgrade their rear differential mounting without detracting from the car's original feel.

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. 

Engineered to perform, Powerflex performance polyurethane differential 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.
