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
Product Development:

Our Chassis Mount Shifters are designed, engineered, tested and quality inspected by our Research and Development team at Turner. Nothing but the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer and rigorous long term product testing.

The factory BMW S65 dual-mass flywheel is engineered with comfort in mind, catering to the luxury-oriented expectations of the brand’s driving experience. Its design focuses on dampening drivetrain vibrations, smoothing out gear transitions, and minimizing harshness during operation. However, this refinement costs valuable performance. The dual-mass flywheel adds a substantial 27 lbs of rotational mass to the drivetrain, which significantly hinders throttle response and makes rev-matching feel sluggish and disconnected. Moreover, dual-mass flywheels are notorious for being a weak link in modified or high-performance builds and can prove costly to replace when they inevitably fail.

Our Single-Mass Lightweight Flywheel Conversion addresses all of these shortcomings with a purpose-built, lightweight, single-mass design that prioritizes performance. Weighing in at only 19 lbs., this design significantly reduces rotational mass, allowing your S65 to achieve its true motorsport potential!

Features & Benefits:

Precision machined from 4140 HT heat-treated chromoly steel for exceptional toughness, even wear properties, and increased durability.
Material quality promotes even wear across the entire friction surface, prolonging component lifespan.
Heat treated to HRC 28-32, tempered to relieve stress and improve dimensional stability.
Hardness improves component wear characteristics.
Black oxide coated for corrosion resistance on non-friction surfaces.
Precision balanced to exceed OEM specification (G16 spec to 175g-mm).
Specifically designed to work with S65 OE-architecture clutches.
Optimized step height maximizes clutch clamp load and offers a prolonged service life.
Performance:

8 lbs. lighter than the factory BMW flywheel!
OEM Dual-Mass: 27 lbs.
Turner Motorsport Single-Mass: 19 lbs.
Faster revs
Improved throttle response and acceleration
Allows for a more engaging driving experience and delivers a feeling of direct connection
Installation:

Flywheel Hardware: For added peace of mind, apply Blue or Orange Loctite when installing factory flywheel bolts that do not come with pre-applied threadlocker.

Ensure precise clutch installation with this specialized alignment tool, designed specifically for N54-equipped BMWs. While most aftermarket clutch kits include a generic alignment tool, many are intended for the N55, which is incompatible with the N54 due to differences in pilot bearing mounting and flywheel design.

This tool is engineered for both 6-bolt (01/2009+) and 8-bolt (-01/2009) N54 flywheels, allowing you to accurately center and align the clutch disc on the flywheel during pressure plate installation. Achieve a hassle-free and precise fit with this essential service tool.

Turner Motorsport Dual Shear Selector Rod (DSSR)

Enhance your N54-equipped 135i or 335i’s driving feel with the Turner Motorsport DSSR. Designed to give your shifter a much more precise and solid connection, this DSSR replaces the OEM selector rod, eliminating the play and deflection that come from single-shear designs. Pair it with a Turner short-shift kit for the ultimate shifting upgrade.

Think of the DSSR as a major upgrade from the single-contact OEM rod, much like riding a bike with two hands instead of one: you have stronger, more precise control over each gear change. With its dual-contact setup, the DSSR “sandwiches” both sides of the shifter and transmission, creating a direct link that feels solid, eliminating the vague and sloppy feel of the factory setup.

Key Benefits:

Enhanced Precision: Significantly reduces deflection and play, giving you a more connected feel while shifting Compatible with Factory & Aftermarket Shifters: Perfect for custom setups as well as stock configurations Durable Build: Fabricated from high-quality 303 stainless steel, offering rust resistance and longevity Complete Hardware Included: Comes with zinc-plated hardware for a secure installation Specifications:

Material: 303 stainless steel construction Compatibility: Replacement for part #25117524722 (E8X/E9X N54 models) Installation Design: Two-piece assembly with captive pins, designed for simple alignment and adjustability Fitment: Specially engineered to fit the tight N54 carrier without interference Installation Tips:

Remove your factory selector rod and take note of its orientation. Attach the DSSR to both the transmission selector joint and lower shift lever. Shift to 3rd or 5th gear for maximum access to the supplied hardware, then secure tightly.
