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!

Product Features:

  • Pre-installed bushing, NO cutting or burning for installation
  • Corrosion resistant 304 stainless steel mounting bracket
  • 70A durometer poly bushing for reduced NVH
  • Ready to install out of the box
  • Replaces Genuine BMW part number 25111220707
  • Made in America

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

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.

FEATURES

Unmatched Strength & Durability - Heavily reinforced mounting locations are designed to withstand extreme horsepower, torque, and shock load. Secondary Differential Mount - A built-in secondary mount, integral sheet metal bracket, and billet adapter plate make this the strongest E30 differential cover on the market. Bolt-On or Weld-On Installation - The secondary mount is designed for easy bolt-in installation or can be welded to the chassis for ultimate rigidity. Optimized Cooling - Large external fins, designed using CFD analysis, dissipate heat efficiently, reducing overall differential fluid temperatures. Integrated Breather System - An integrated breather system reduces internal cavitation by properly venting built-up pressure. Enhanced Fluid Management - Includes a 1/8 NPT sensor port for real-time fluid temperature monitoring, and optional -6AN fittings for adding an external fluid cooler. Aerodynamic Air Duct - The included aerodynamic air duct further reduces fluid temperatures, increasing fluid service life and reliability. KIT CONTENTS

Red Line 75W90 is a full synthetic high-performance gear oil that is an excellent substitute for expensive factory fluid and an upgrade over off-the-shelf economy fluid. Red Line thoroughly evaluates the manufacturer's recommendations and only makes a fluid recommendation if their own product meets or exceeds the original specification. In many cases the Red Line synthetic will outperform the factory supplied fluids. We've been using Red Line Oil in our BMWs since we opened in 1994 and it remains our best selling BMW differential fluid. 75/90 is the weight most commonly used in BMW differentials since the 1960s, including the factory clutch-type limited-slip diffs (exceptions being M3/M5/M6 cars since 2001). We use 75W90 in nearly all BMW chassis and the custom differentials that we sell. It's great for the street where the polyol-ester base has natural lubricity and friction modifiers lead to smoother and quieter operation with lower operating temps than the factory fluid. We also use it in some track cars that don't already use the more aggressive 75/90NS fluid (without friction modifiers).

Recommended or exceeds specifications for API GL-5, GL-6, MT-1, MIL-L-2105E, SAE J2360, and Chrysler spec MS-9763. Matches the specifications for the factory BMW SAF-XO diff fluid (#07512293972).

RED LINE MT-90 is designed to provide excellent protection and improved shiftability for manual transmissions and transaxles. MTL and MT-90 have cured the problem of hard shifting in numerous transmissions which have notoriously difficult shifting. The secret to their success is two-fold. First, they have the appropriate coefficient of friction for most manual transmission synchronizers. Many gear oils, engine oils, and ATFs are too slippery for proper synchro engagement. Secondly, the viscosity characteristics of MTL and MT-90 allow proper shifting over the entire temperature range which the transmission will experience. The synthetic base oils used have a very high viscosity index which provides relatively constant viscosity as temperature changes. MTL is a low 75W, almost a 70W, at very low temperatures and a high 80W, nearly an 85W, at elevated temperatures, providing adequate viscosity to prevent wear and deaden gear noise. MT-90 is a thicker 75W90 version of MTL. The shear stability and oxidation stability of these products are excellent, thus the physical characteristics of Red Line MTL and MT-90 will change little with use.

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.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

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

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.

Red Line 75W90 is a full synthetic high-performance gear oil that is an excellent substitute for expensive factory fluid and an upgrade over off-the-shelf economy fluid. Red Line thoroughly evaluates the manufacturer's recommendations and only makes a fluid recommendation if their own product meets or exceeds the original specification. In many cases the Red Line synthetic will outperform the factory supplied fluids. We've been using Red Line Oil in our BMWs since we opened in 1994 and it remains our best selling BMW differential fluid. 75/90 is the weight most commonly used in BMW differentials since the 1960s, including the factory clutch-type limited-slip diffs (exceptions being M3/M5/M6 cars since 2001).

As your E30 ages, the rear differential bushing can crack, dry rot, and split. It's time for an upgrade. The ECS Tuning Heavy Duty Differential Bushing is crafted with performance in mind. Instead of using polyurethane, which is known for increasing NVH, the enthusiasts at ECS chose HD 70D rubber. This material offers a close-to-factory feel without the excess deflection of softer bushings, ensuring a pleasurable driving experience free from differential whine and excess movement.

Features & Benefits:

Eliminates Weak OEM Mount: The aging E30 chassis deserves an upgrade. Replace your old, cracked, and worn factory bushing with this HD alternative for improved performance. Perfect for Street or Track: Constructed from HD rubber instead of polyurethane or Delrin, this bushing provides comfort for daily driving while remaining effective in performance applications. Added Responsiveness: The 70D HD rubber compound is stiffer than the stock material, reducing drivetrain movement and effectively locking down your rear differential. Easy Installation: Precision-manufactured to the exact specifications of your OEM differential bushing, the ECS heavy-duty replacement installs just like the factory component. Whether you are replacing an aging factory bushing, removing excess driveline movement, or balancing performance and comfort, ECS Tuning has you covered with their Heavy Duty Rear Differential Bushing.

Stock rubber flex discs allow for a slight amount of give, especially under heavy acceleration and, depending on the amount of force applied, could potentially tear or split. This slight flex/give can prevent instantaneous transfer of force to the wheels, making accelerations unpredictable, or even lead to your vehicle being stuck on the side of the track. To combat this, IRP's Performance Flex Disc was developed. Made of CNC machined aluminum, this flex disc won't actually flex, and the polyurethane bushings will only provide a enough give to dampen some vibrations and prevent damaging the transmission. This is perfect for high torque applications such a drag cars and dedicated track cars that want immediate response and long term reliability.

This replacement flex disc (aka: the guibo) is a vibration dampener mounted on the back of the transmission which connects to the driveshaft. When it has worn, it produces a terrible vibration throughout the car. It's especially noticeable at low speeds and when starting from a standstill. Oil leaking from the back of the transmission will significantly reduce its life. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

Max Gear is a high-performance automotive gear oil designed to provide maximum protection to heavily loaded gears while increasing power throughput through the drive train. Max Gear virtually eliminates both gear and bearing wear—even under severe squeeze film conditions caused by extremely high loads, sudden shock loads, or low RPMs. Slippery, synthetic molecules not only reduce wear and friction but significantly increase Max Gear’s cold weather fluidity and lubricity, making it the ideal choice for vehicles operating in cold climates. Gears run smoother, quieter, cooler, and longer without overhauls. It is non-corrosive to both ferrous and nonferrous metals.

Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This, in turn, reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

The stock center support bearing carrier is designed to reduce NVH to the cabin by loosely holding the center bearing with a flimsy rubber bushing. During launches and shifts, the driveshaft is allowed to travel off-center, decreasing throttle response and causing oscillations through the drivetrain. As they age, the carrier rubber sags and dry rots, ruining the driveshaft alignment. Fix or prevent this common issue with JXB Performance's Driveshaft Center Support Bearing Upgrade! JXB utilizes a simple but extremely effective 2-piece design which allows you to install this upgrade and replace bushings with ease. The stock center support carrier is simply cut away, allowing the JXB bushings to "clamp" down on the driveshaft bearing and hold the driveshaft securely in place, maintaining driveshaft alignment at all times. Two bushing options are available for this kit, Street and Track, both of which are many times better than the stock bushings: The street bushings absorb most of the NVH from the drivetrain. Some light NVH is possible at some speeds in the form of a soft hum. (With a modified exhaust or windows down, you’ll probably never hear it) The track bushings are for those who want no-compromise drivetrain performance. These may create a substantial amount of cabin noise. Not sure which is for you? Try them both, they’re interchangeable! Installation does not require the removal of the driveshaft. The 2-part design clamps around the OEM bearing. The old carrier must be removed, so a cutting tool is required. Looking for replacement or additional bushings? See T#4799658 for replacement street bushings and T#4799659 for replacement track bushings.

Aluminum flywheels are much lighter than the stock steel flywheel and that produces better throttle response and more available horsepower to the wheels for faster acceleration. The JB Racing aluminum flywheels are a direct replacement for the stock flywheel and work with stock clutch components for an easy upgrade with very little downside.

Modern flywheels are built with additional components and features that are designed to dampen and minimize vibrations from the engine and transmission. As a result they have become bloated in weight and that means more energy is used up just making the flywheel spin. The weight difference between an aluminum and steel flywheel is huge - sometimes more than 50% less. Without the additional mass, more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance.

In addition to releasing more power to the wheels, the lighter flywheel allows the engine to spin more freely, which improves throttle response. Again, the difference is huge as you watch the revs build faster than before. With the engine spinning easier the power band comes up much sooner. The stock steel flywheel feels lazy in comparison. There is a driving adjustment required to get used to how much faster the engine revs but that's not really a downside.

The JB lightweight flywheel is designed to be used with a factory organic clutch - the same clutch kit that you would get from any BMW dealer. This makes replacement clutch components easy to source and inexpensive when compared to specialized racing clutches. By using the factory BMW clutch, JB has also made the whole assembly easy to live with when used on the street. The clutch behaves the same as it originally did - just with better throttle response and more power! The JB flywheel can also be rebuilt with a new clutch contact surface - you don't have to buy a new flywheel.

Aluminum flywheels are considered 'single-mass' flywheels because they do not have the same dampening designs as an original 'dual-mass' flywheel. With a single-mass design more noise and vibration may be noticeable. There are steps you can take to minimize the noise - heavier weight transmission oil and clutch discs with anti-rattle springs (sprung-hub clutch).

The JB flywheel includes ignition trigger wheel.

Stock Flywheel Weight = 19.5lbs
JB Flywheel Weight = 8.0lbs
