Turner Motorsport BMW Drivetrain Parts

New for your 6-cylinder Z3 is our Dual Shear Selector Rod (DSSR) to deliver a more controlled and tighter shifting experience over the factory selector rod. 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).

This item fits the following BMWs:
2006 E90 BMW 330i - Sedan

Single piece 6061 construction, optimized cooling, provisions for temp sensor, and external cooler with removable air duct.

Built to last, made from a single piece of 6061 billet aluminum with a rugged and good-looking hard-coat anodizing the Turner diff cover can handle anything you throw at it. Not only is it an absolute masterpiece, but this billet diff cover checks all the boxes for features needed. Reinforced mounting ear for strength and stability. The mounting ear is unified with the one-piece billet cover and features added material for the highest durability possible. This diff cover is cool, literally, the entire construction was designed with optimized cooling in mind. External fins are strategically placed on the rear face, bottom, and between the mounting ears of the cover, serving as effective heat sinks for optimal heat dissipation. This ensures stable temperatures, promoting longevity for both the fluid and your differential. Additionally, the internal design ensures continuous oiling and lubrication of the ring gear, maintaining its stability and preventing fatigue by controlling heat more effectively. An internal baffle at the cover's corner helps maintain proper pressure and prevents cavitation.

All of the OEM features were retained along with the upgrades. The drain and fill plugs on the diff cover are upgraded to -6AN using the provided high-pressure fittings with replaceable o-rings. The drain and fill plugs can now be used for an external oil cooler allowing you to further expand the fluid capacity for optimized cooling and service intervals. To keep an eye on things from the driver seat is 1/8 NPT provision for temp sensors, this product from Turner has you covered at every turn.

Upgrading to our Turner Billet Differential cover gives you the strength you need to push your car to its limits without worrying about snapping a diff mount from clutch kicking or other shocks to the drivetrain. In addition to its enhanced strength, this differential cover includes numerous other upgrades and conveniences. These include improved cooling and lubrication for the ring gear, upgraded fill and drain plugs, and the option to expand an external oil cooler for extreme motorsport usage. Designed to complement both upgraded daily drivers and extensively modified track cars, it also offers a visually appealing design.

Key Benefits:

Reinforced mounting ear for strength and stability
16% Increased fluid capacity
External fins on the back side, bottom, and mounting ear on the casing for maximum cooling and consistent fluid temps
Removeable air duct to direct air across the cooling fins for even more temperature control
