Shifter Upgrades and Components

Our Turner Motorsport rear shifter bushing is a precision-engineered solution designed to eliminate excessive deflection in the factory BMW G8X shift carrier assembly. The OEM rubber bushing introduces unwanted compliance that translates to a vague shifter feel, imprecision under load, and potential gear misalignment during aggressive driving. This polyurethane and billet aluminum replacement addresses that with a focused approach to both material selection and mechanical function.

Our engineer replaced the soft rubber isolator with a 70A durometer polyurethane bushing housed in a CNC-machined 6061-T6 aluminum body. The result is a significant reduction in bushing deflection while retaining the necessary articulation for BMW’s dual-bushing shift carrier design. Strategically placed relief cuts in the poly insert allow controlled movement without compromising rigidity where it matters most, translating to a more direct, confident shift feel without introducing harsh NVH into the cabin.

By maintaining stock geometry and compatibility with OEM components, this bushing installs as a direct replacement for BMW part #25118623459, with no modification required. Ideal for spirited street driving, track use, or anyone seeking a more mechanical and connected shift experience.

Technical Specs:

70A polyurethane construction for optimal stiffness-to-compliance ratio
CNC-machined 6061-T6 billet aluminum housing
Type II anodized for corrosion resistance
Retains dual-axis articulation of factory shift arm
Direct fitment for G80 M3 / G82 M4 / G87 M2 (with manual transmission)
Performance Gains:

Drastically reduces lateral and fore-aft play in the shifter
Improves shift precision, especially under load or high-RPM shifts
Minimizes missed shifts and sloppy gear engagement
Maintains daily drivability with near-OEM NVH levels
Whether you’re chasing lap times or just want your daily to feel more dialed in, this rear shifter bushing is a must-have for restoring and upgrading the mechanical precision BMW’s manual platform deserves.

If you’re looking to take things a step further, adding our Dual Shear Selector Rod and Short Shifter is a great way to build on this upgrade and unlock even more shift feel and precision—whenever you’re ready

We have always loved BMWs, but one of their shortcomings has always been shifter throw and feel. Even driving your new BMW ///M home from the dealership, you might realize that the shifter throw leaves something to be desired when you find your right hand in your backseat when shifting into fourth gear. Things only go downhill from here, as these cars increase in age and mileage shifts feel less and less precise. Our short shifter offers 32 to 40% reduction in throw over stock. Note that this short shifter differs from our typical Turner short shifter in that it is solely height adjustable, not throw.

Note that we did notice some resonance when testing on vehicles with factory base model shift knobs (25117596084 or 25117596086, etc). We recommend running ZHP, M, or M Performance to both avoid this and give your shifts the best feel.

Sometimes choosing the correct shift kit proves difficult when you dual-purpose your favorite vehicle, we understand this well. The early days for any race enthusiast usually begins with a car that is needed to daily drive and setup to get out on the track. What becomes difficult is properly modifying that car to feel comfortable in both situations which is why we took this view on our new short shift line. This upgraded lever is a quick swap option to replace the standard shift lever that come with our kits so you can keep your hands closer to the wheel while shifting at high speeds. Designed from anodized aluminum this lever looks great in any interior for the daily driver who simply prefers the taller lever look and feel.

NOTE THAT THESE ARE DESIGNED TO WORK WITH TURNER MOTORSPORT SHORT SHIFTERS ONLY - We wanted to give you the option to buy one separately, in case you changed your mind after buying our short shifter.

Features:

Compatible with stock shift boot fits nicely into the machined groove at the bottom of the lever to maintain a clean look in the interior.
Machined from 6061-T6 aluminum and type II anodized for exceptional durability and corrosion resistance.
Available in either black or clear anodize to match your vehicle’s interior.
Rally shift knob is machined from black delrin.
Unlike aluminum, delrin will not hold heat so on those hot days you won’t have to worry about burning your hand on a knob that’s been baking in the sun.
Shift knob is threaded onto the end of the shift lever utilizing a standard ⅜-16 thread to allow for easy removal and attachment of your favorite beer tap or other accessory.
“Quick Change” height adjustable upper shift lever design allows for quick swapping between optional “OE” style and “Rally Style” upper shift levers.
22mm adjustment range to fine tune shifter throw and feel.

The 6-speed Getrag 420G transmission, found in the European E36 M3 Evolution and E46 M3, has become an increasingly popular swap amongst E36 owners. Its increased strength, longevity, and overdrive sixth gear make it a great choice for both track cars and daily drivers. Unfortunately, many of the components needed to complete this transplant have become hard to source. Despite increased demand from enthusiasts, BMW has blocked the sale of European E36 M3 parts into North America.

With this in mind, our team of engineers went to work designing a direct replacement and upgrade for the unavailable, 420G-specific shifter arm. Precision-machined from 6061-T6 billet aluminum and clear anodized, our replacement carrier is durable, lightweight, and built to last. It is dimensionally identical to the OEM carrier, ensuring compatibility with the OEM shift carrier bushing, shift lever, and our Double-Adjustable Short Throw Shifter Kit (T#557266).

Unfortunately, many of the components needed to complete this transplant have become hard to source. Despite increased demand from enthusiasts, BMW has blocked the sale of European E36 M3 parts into North America.

Recognizing this issue, we set out to develop a replacement for the unavailable, 420G-specific selector rod. Like all OEM selector rods, the factory part uses single-shear attachment, allowing for deflection within the shifter linkage. The result? Vague, imprecise gear selections that detract from your overall driving experience. The dual-shear selector rod (DSSR) design spreads the torsional force of gear selections across the selector rod joint, reducing deflection for increased precision. Our dual-shear selector rod is precision-machined from durable 304 stainless steel to further reduce deflection and resist corrosion.

Pair our Z3 DSSR with our upgraded poly rear shifter bushing for the full upgraded shifting experience. This DSSR is designed for Z3 models that have the selector rod p# 25111222780.

Upgrade from your single connection selector rod to a dual shear selector rod or DSSR for a stronger connection and an overall better shifting experience. The factory BMW selector rod is made of hollow aluminum tubing and attaches to both the shifter and transmission from one side utilizing a pin-and-clip design. The factory single-side attachment only has a small amount of surface area contacting both the shifter and transmission selector which relies directly on the connecting pin to do all of the shifting and control, this can cause a loose and/or lackluster experience when shifting gears or shaking your shifter in neutral. Your new Turner DSSR features a much larger contacting surface to both the shifter and transmission, not only does the upgraded DSSR have larger faces contacting your shift components but it also features double the amount of mounting surfaces. This dual shear selector rod hugs your shift lever and selector tight from both sides and eliminates deflection and sloppiness for the best shifting experience possible.

Oftentimes, the first thing you will notice about your manual BMW is that the stock shifter throws are miles and miles long. We developed our short shifter kit as a solve for this common complaint about manual transmission BMWs. Our new short shifter kits are the culmination of years of research and development - we went back to the drawing board several times throughout the design process, in efforts to release a product that really stood out from the rest of the short shifters on the BMW market. We set out to design the perfect shift kit for your BMW. Now we realize perfect is a subjective term, so we gave our short shifter a wide range of height and throw adjustability. This wide range of adjustability allows you to easily make adjustments from the cabin of your BMW by just removing your shifter boot and using small hex head keys.

We made our short shifter for all of you. The weekend warriors, the trackday monsters, and even the daily drivers. We wanted to make something that made sense for any BMW enthusiast. For those who want to drive your car to the track, drive some hotlaps, and then drive back home, we developed a rally lever extension. Our rally lever extension allows you to keep your hands close to the steering wheel through shifts, in efforts to quicken shifts and reaction times on the track. The rally lever comes off and on in seconds with the unique locking design we engineered. After your track day win, you can easily swap back to the short lever for more comfortable daily driving.

Installation of this kit is one of the easiest to take on compared to the competition - our custom bearing cup allows for easy installation from inside of the car (on applications that use the stock shifter arm).
