BMW Drivetrain Parts for BMW 8 Series E31 (1991-1997)

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.

Even after rebuilding your manual transmission shifter with brand new BMW components or installing a short shift kit, your shifts will still be at the mercy of soft factory bushings. 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 ULTIMATE shifter upgrade for your BMW! Experience more precise throws, less shift lever travel, and an all-around transformation in your shifting experience.

For dozens of years, enthusiasts have critiqued the imprecise and vague feeling of BMW manual transmissions. Plagued with long throws, fore and aft play in gear, and a generally loose feeling, your OEM BMW shifter leaves much to be desired. While most standard carrier-mount short throw shifter kits will aid in reducing throw length and eliminating side-to-side play in gear, some enthusiasts long for a hardcore, race-inspired shifter that completely removes play and excessive throw length. At Turner Motorsport we share the same desire and set out to offer the ULTIMATE upgrade with this Performance Chassis Mount Short Shifter.

WHY UPGRADE?

Factory BMW shifter assemblies are complex by nature. The main component of this assembly is the shift carrier, a cast aluminum piece positioned inside the transmission tunnel that incorporates bushings at both ends for mounting. Like most factory parts, these bushings are designed to reduce NVH (noise, vibration, and harshness) transmission to the cabin. To the spirited driver, however, these bushings translate to flex and vagueness in the shift lever. Moreover, because this carrier is mounted to both the transmission and the body, the entire shifter assembly will "float" with the driveline, further increasing the vague and imprecise feeling of your shifter.

Our Performance Chassis Mount Short Shifter removes the shift carrier assembly entirely—removing any prospect of flex caused by bushings or driveline movement. By contrast, this chassis mount shifter offers a drastic reduction in shift lever travel, vagueness, and side-to-side play. An elevated base allows for moving the fulcrum point upwards, resulting in a much shorter and more precise throw. Shift times are further reduced by a tall, "rally style" shift lever, used to aid in leverage while also bringing the lever closer to the steering wheel. Our design incorporates a proprietary centering spring design, which is adjustable for increasing or decreasing self-centering force. In short, this design eliminates all the drawbacks of your factory BMW shifter, translating to more control, greater precision, shorter throws, and faster shift times.

FEATURES & BENEFITS

Reduced Throw: Modified shifter geometry and heightened fulcrum point translate to a shorter shift lever throw
Improved Shifter Feel: Eliminating the shift carrier and associated bushings drastically reduces "slop" and side-to-side play in the shift lever
Increased Precision: Mounting the shifter to the chassis allows for little to no variation in gear selection
Universal Fitment: Fits many BMW chassis with the provided base plate and hardware (see "Fits These Cars" for exact fitment information)
DESIGN

6061 aluminum, 4130 steel, and 316 stainless steel construction
A type-II black anodized finish
Adjustable self-centering spring
"Rally Style" shift lever
Spherical bearing pivot with maintenance-free brass insert

  6. Wide Compatibility:

    • Suitable for a range of BMW models, these bushings are a versatile and valuable upgrade or replacement for drivers looking to restore or improve their vehicle’s shifter performance.

Benefits of Upgrading or Replacing:

  • Tighter Shifting Feel: New oval bushings restore precision to the shifter assembly, eliminating the slack that develops over time in worn bushings, providing a more connected driving experience.
  • Reduced Vibrations and Noise: Fresh bushings help dampen vibrations and reduce noise from the shifter assembly, contributing to a smoother, quieter ride.
  • Extended Shifter Life: By maintaining proper alignment and reducing stress on other components, replacing old bushings can help extend the life of the entire shifter assembly.
