Vague or slopping shifter feel even after installing a short shifter or new OE shifter linkage bushings? Looking for a more precise shifter feel in your classic BMW? Consider replacing your old, worn rubber rear shifter bushing with new Turner poly to get the best shifting experience possible! The Turner engineering team wasn’t satisfied with the other options on the market, so we set out to design the best solution for ease of installation and performance.
The competition requires the installer to cut or burn the rubber bushing out of the stock housing to be able to install their poly bushing, requiring reuse of an old worn out housing, or buying a new costly bushing assembly. We decided this was cumbersome and unnecessary, so we designed a complete upgrade replacement bracket with a 70A polyurethane bushing preinstalled for a quick bolt-in installation. Our bracket is precision formed with a CNC machined and TIG welded bushing cup to perfectly match the OEM bracket, and is made from 304 stainless steel for exceptional corrosion resistance. The result is a complete design solution that creates much crisper shifting with nearly zero added NVH for a more engaging and enjoyable driving experience.
Note: Some shifter arms have a mushroom-shaped end. Use extra care installing our bushing on these arms. Filing this mushroom down makes installation easier, however simply applying sufficient pressure to the back side of the bushing during installation will allow this bushing to install smoothly.
This is the last bushing you will ever want or need for your E28, E30, or E34!

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

Designed for track drivers, drift enthusiasts, and drag racers alike, this all-in-one driveline upgrade eliminates the factory weak points and reinforces your drivetrain for high-performance abuse. Whether you're laying down 500HP, clutch-kicking through corners, or launching hard at the strip, this cover keeps your differential secure, cool, and ready for battle.
The stock E30 differential cover features a single mounting provision—fine for a stock M20, but guaranteed to fail on your boosted high-horsepower M5X build. After years of broken covers, mounting tabs, and dreams, our team of E30 enthusiasts engineered the ultimate fix.
Unlike the brittle OEM cast aluminum cover, our upgraded differential cover is CNC-machined from 6061-T6 billet aluminum, offering a 30% increase in material strength alone. More importantly, a secondary mounting ear has been integrated into the design for added support, drastically improving stability and driveline shock absorption. The secondary mount is tied into the chassis using a reinforced sheet metal bracket and a billet aluminum plate, allowing for bolt-on installation or welding for ultimate rigidity.
Another major flaw of the factory E30 differential cover is its lack of any cooling provisions, leading to overheated fluid and premature wear. Our engineers solved this issue by incorporating advanced cooling features into the design. Large external fins have been added to the cover, and are optimized using CFD (Computational Fluid Dynamics) analysis to efficiently dissipate heat, reducing overall fluid temperatures. By maintaining a more stable differential temperature, this cover ensures consistent performance and extends the lifespan of your differential fluid. A built-in air duct assists in cooling by increasing airflow around the differential, further preventing heat-related failures. Our cover features optional -6AN fittings, allowing for easy integration of an external fluid cooler if desired. Finally, a 1/8 NPT port is included with the kit to ensure compatibility with fluid temperature monitoring systems.
Precision-machined from 6061-T6 billet aluminum and finished with a black hard coat anodizing, this cover is built to withstand hard use. Despite its robust construction and superior durability, this differential cover retains factory mounting features. This means any E30 188mm differential cover bushing can be installed, allowing you to tailor our upgraded cover to your build. The cover also accommodates large rear sway bars, ensuring fitment on cars with upgraded suspension. Our proprietary removable air duct provides easy access to sensor bungs, fill plugs, and drain plugs, making differential service a breeze.

Some modifications to your vehicle may not produce power to create gains in the overall performance of your driving. When you add a "Po' Boy" clutch stop to your BMW the performance gain is directly felt in the driving experience.
The ECS clutch stop allows the driver to fine tune the position of the clutch pedal to closely match the engagement point for precise, quicker shifting. The adjustment range found in this product can be set to the stock engagement point or can be adjusted to follow the wear of the clutch. Meaning your new experience will never change all the way to the end of the clutch life and can be reset to enjoy the next clutch.
Note: This modification might require some slight modification to the clutch switch mounting bracket, which can be bent slightly by hand.
This braided stainless steel line replaces the stock hydraulic hose connecting your clutch slave cylinder to the clutch master cylinder. There are several deficiences with rubber, especially as it ages - when new the rubber expands and swells under pressure and the pedal can feel spongy. As rubber ages and is exposed to extreme temperatures the rubber can harden and even shrink (common on brake hoses), which results in a stiff pedal. Rubber clutch lines do not stand up to the stresses of hard use. ECS Exact-Fit stainless reinforced clutch lines provide more confident and dependable shifting by maintaining consistent line pressure, long lasting corrosion resistance, and increased protection from failure. These lines are reinforced with braided stainless steel mesh, affording superior expansion resistance. This resistance to expansion creates a firmer pedal, and a more direct clutch pedal feel. The signature red polymer coating provides additional protection from the elements and abrasion.
This particular stainless steel clutch line fits the following BMWs:
1984-1991 E30 BMW 318i 318is 318ic 325e 325es 325i 325ic 325is 325ix M3
1988 E28 BMW M5
1987-1989 E24 BMW M6

This Differential Fluid Extraction Adapter is a must-have for any vehicle owner looking to maintain the longevity and performance of their differential system.
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.
