BMW Drivetrain Parts for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

Please ensure your correct model is selected

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

Even after rebuilding your manual transmission shifter with brand new BMW components or installing a short shift kit, your shifts will still be at the mercy of soft factory bushings. Designed with 100% comfort and low manufacturing costs in mind, BMW's factory carrier bushing offers a freedom of movement on all axis, resulting in "factory installed slop".

The ZF S5D 320Z 5-speed transmission is known for its robust design, exceptional durability, and impressive power-handling capability. Unfortunately, as these transmissions age, shifter-related issues have become increasingly common. Problems such as difficulty selecting gears, a sticky shifter, or a decline in shift quality are often the result of worn detent springs, pins, and bushings. These components are essential for precise gear engagement and proper shifter centering, making their replacement a critical step in maintaining optimal performance.

Replacing detents requires specialized tools known as "drifts," which are notoriously hard to find. Fortunately, we've developed a complete Detent Tool Kit, featuring five precision-engineered drifts designed for exact fitment in the ZF transmission's detent bores. This toolset makes detent replacement straightforward and minimizes the risk of damage to internal transmission components.

Features

Complete Tool Kit: Includes five precision-machined drifts specifically designed for the ZF 5-speed transmission’s detent bores and caps. Hassle-Free Detent Replacement: Simplifies the process of removing and installing detents with professional-grade precision. Protects Your Investment: Reduces the risk of damaging internal transmission components during service. Durable Construction: Made from heavy-duty 1045 steel for exceptional strength and long-lasting reliability.

If you've ever bled the clutch hydraulic system on your BMW, you know how frustrating it can be. Designed with both DIY enthusiasts and professional technicians in mind, our clever tool simplifies one of the most notoriously annoying steps in clutch service.

Crafted from high-quality aluminum and finished in a durable black anodized coating, our clutch slave cylinder bleeder tool is built to last. Its function is simple: the adjustable piston rod applies controlled pressure directly to the clutch slave cylinder’s piston, compressing it and reducing its internal volume. By minimizing the amount of air trapped inside the cylinder, bleeding becomes faster, cleaner, and far more effective—no more endless pedal pumping or inconsistent clutch feel. The result is firm, consistent clutch pedal engagement and a smoother overall driving experience, all achieved with less time and effort underneath the car.

FEATURES & BENEFITS

Simplifies bleeding the BMW clutch hydraulic system by reducing trapped air in the slave cylinder Eliminates excessive pedal pumping and inconsistent clutch feel Helps achieve firm, consistent clutch pedal engagement Crafted from high-quality aluminum for strength and longevity Durable black anodized finish resists wear and corrosion Designed for both DIY enthusiasts and professional technicians PRODUCT DEVELOPMENT

Our Clutch Slave Cylinder Bleeder Tool was 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.

We know if a soft mount offers a sloppy connection it doesn't work on the track, and a solid mount isn't acceptable as a daily driver (for most!) and set out to engineer a mount that would meet the needs for both. At the core of our enclosed design is a partially-constrained, multi-piece polyurethane bushing with precisely-set preload. This architecture absorbs and disperses resonant engine frequencies as opposed to amplifying them (like some other designs do), which results in a positive-connection, enthusiast-feel mount with the vibration.

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.

We have always loved BMWs, but one of their shortcomings has always been shifter throw and feel. Even driving your BMW 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. Here at Turner, we CAD design everything in house and source the best materials to give you a truly amazing product and enhance the driving experience in your ultimate driving machine. After extensive testing and development, we are proud to present you with our Turner Motorsport short shifter. We wanted to develop something that could fit any BMW owner’s preferences - our engineering team decided this could be designed a height and throw adjustable short shifter that also features a “Quick Change” rally lever extension that allows you to easily swap back and forth between OE height shifter and the longer, rally lever you see in the product photos. Why the rally lever extension? Having the added height allows you to keep both hands closer to the wheel through shifts - this is especially helpful on the track, but we like it in our daily drivers too.

If allowed in the rules these solid aluminum transmission mounts offer many advantages over a urethane or Delrin mounts. It's no wonder that these mounts have found their way into the top BMW racers in the country. These are machined from solid aluminum and have zero deflection, engine torque will cause a rubber or urethane mount to flex or deflect allowing more torque to passed through the drive line (instead of being wasted winding up the mount). This puts the shift linkages in better consistent alignment. And unlike rubber or urethane the aluminum has zero wear and is not affected by leaking oil or other fluids so this is likely the last set of transmission mounts you will ever need. We very strongly recommend using the solid transmission and engine mounts together as a complete kit, mixing a rubber mount with a metal mount will cause undue stress on the mounting points and will lead to a failure. We never advise using a solid mount unless a corresponding solid mount is also used.

These are a no-compromise design for all-out racing use, full solid aluminum mounts should not be used on street-driven cars since there is no material to absorb vibration making these quite harsh for regular street use (track cars don't care about noise).

Product features and benefits:

  • Crisper throttle response, positive shifter location, direct power transfer
  • Precision machined billet 6061-T6 aluminum housing
  • Grade 10.9 stud - fear not, big turbo owners
  • Engineered in-house and 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
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.

Made in the USA For our Grand-Am Cup E46 M3s we wanted a fully solid differential mount setup. The advantages of a fully-solid aluminum set is that they last forever, quickens response in the suspension, and frees up horsepower to the wheels. These fully solid aluminum diff mounts are CNC machined and lightened for a direct replacement of the original rubber pieces.

By substituting aluminum for rubber we can take out all of the deflection and 'wind up' inherent to the original rubber pieces. The high deflection rate of the stock rubber means the suspension reacts slower as the bushing is compressed. The power used to compress that bushing is instead passed straight to the axles and wheels. And since there is no time lost to deflection, response is greatly improved. These diff mounts are only recommended for racecars since the aluminum transfers more noise and vibration.

This is a 3-piece set with a single front bushing and two rear bushings to press into the cover. They mount with the stock BMW hardware.

This item fits the following BMWs:

Single piece 6061 construction, optimized cooling, provisions for temp sensor and external cooler!

Built to last, made from a single piece of 6061 billet aluminum with a rugged and good-looking hard-coat anodizing our diff cover can handle anything you throw at it. Not only is it an absolute masterpiece to look at but this billet diff cover checks all the boxes for features needed. Reinforced mounting ears for strength and stability, never again will you break an ear off your diff cover like the factory units are known to do. Each 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. Internal fins are strategically placed 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 mounting surface was designed to be compatible with both the OEM gasket or RTV of your choosing, some people don't trust the gaskets and we get it. Factory bushing geometry allows you to use any E46 diff busing including rubber, poly, and even solid mounts. 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 also be used for expanding to 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.

Why the upgrade?

Upgrading to our Billet Differential cover gives you the strength you need to push your car to its limits.

For our Grand-Am Cup E46 M3s we wanted a fully solid differential mount setup. The advantages of a fully-solid aluminum set is that they last forever, quickens response in the suspension, and frees up horsepower to the wheels. These fully solid aluminum diff mounts are CNC machined and lightened for a direct replacement of the original rubber pieces.

By substituting aluminum for rubber we can take out all of the deflection and 'wind up' inherent to the original rubber pieces. The high deflection rate of the stock rubber means the suspension reacts slower as the bushing is compressed. The power used to compress that bushing is instead passed straight to the axles and wheels. And since there is no time lost to deflection, response is greatly improved. These diff mounts are only recommended for racecars since the aluminum transfers more noise and vibration.

This is a 3-piece set with a single front bushing to be pressed in and two rear bushings pre-pressed into the cover. They mount with the stock BMW hardware.

This item fits the following BMWs:
2001-2006  E46 BMW  M3

Made in the USA If allowed in the rules these solid aluminum engine and transmission mounts offer many advantages over a urethane or Delrin mounts. It's no wonder that these mounts have found their way into the top BMW racers in the country. We originally developed these mounts for E36 and E46 World Challenge racing but they also work perfect in BMW Modified and SCCA club racing and SpecE46 (SE46). These are machined from solid aluminum and have zero deflection. The engine torque will cause a rubber or urethane mount to flex or deflect. The stiffer the material the less movement there is and the more torque is passed through the driveline (instead of being wasted winding up the mount). At the transmission end the flex-free solid mounts will give smoother, crisper shifts since the transmission is no longer dancing on the pliable mount. This puts the shift linkages in better consistent alignment. And unlike rubber or urethane the aluminum has zero wear and is not affected by leaking oil or other fluids so this is likely the last set of motor and transmission mounts you will ever need. We have designed these mounts so the engine is 5mm lower and the transmission is 1mm lower than the factory mounts. This helps lower the center of gravity for better balance and handling. We very strongly recommend using the transmission and engine mounts together as a complete kit. Mixing a rubber mount with a metal mount will cause undue stress on the mouting points and will lead to a failure. We never advise using a solid mount unless a corresponding solid mount is also used. This kit fits the E36, E46, Z3, and Z4 6 cylinder models listed below, including M3 models.

These are a no-compromise design for all-out racing use. Full solid aluminum mounts should not be used on street-driven cars. Because there is no material to absorb vibration these will be quite harsh for regular street use (track cars don't care about noise).

Subframe reinforcement kits are very strongly recommended to go along with these solid motor mounts to reduce the risk of damage to the subframe. The motor mount section of the subframe should be reinforced to prevent stress and failure of the subframe.

This item fits the following BMWs:
1992-1999 E36 BMW 323is 323ic 325i 325is 325ic 328i 328is 328ic M3

Stock mounts are made from soft rubber and are sometimes filled with fluid to give a car the most comfortable ride possible. The soft rubber and fluid helps to reduce the total amount of vibration, noise, and harshness (NVH) that is transferred into the cabin. The problem with this is driveline slop. The stock mounts allow a lot of excess movement and increases the amount of time it takes to transfer power to the wheels.

In order to address this issue, performance mounts can be substituted to reduce the amount of slop and transfer power to the wheel quicker. Two options for this are polyurethane mounts and solid mounts.

Solid mounts are great for an immediate transfer of power but allow for a ton of noise and vibration to be felt and heard in the cabin of the vehicle. This is great for the track where there aren't any issues with excess harshness, but as a daily driver, this can become an annoying pain in the neck.

The best middle ground is Polyurethane. Polyurethane is much stiffer than rubber and gives you the much stiffer feel you may be looking for. This allows for the increase in responsiveness, but isn't so extreme that it transfers all of the sound and vibrations into the cabin. This makes it much more comfortable for daily use while still reinforcing your driveline.

Features:

  • Aluminum and Polyurethane Construction
  • 80A Durometer Rating
  • New Hardware

The best way to gain a prominent advantage over the competition is to do it with the MFactory Helical Limited Slip Differential. The smooth consistent distribution of power to the wheels with the MFactory Helical LSD puts the power to the ground and maximizes your vehicle's traction. A must for any car be it street, strip, or track. What exactly does an LSD do you ask? well without an LSD your car is actually 1 wheel drive, in that it can't supply torque to both wheels at the same time and will only supply torque to the wheel with less grip, which is what the shortfall is to an open differential (what most vehicles have). An LSD only lets the wheels spin at different speeds by a limited amount (typically this is a percentage difference) which is when the differential locks and both wheels get power. This is not how locked differentials work such as in off road trucks which supply equal torque and rotational speed to both rear wheels at the same time, which can cause issues with handling.

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. 

Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm 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.

One of the most satisfying upgrades you can make to your BMW is to its factory shifter mechanism. By reducing the shifter's throw, you can give your manual transmission BMW a sportier, more precise feel. However, with so many different "short shift kits" out there, how can you be sure you're making the right decision? With the introduction of the Rogue Engineering OCTANE short shift kit, the choice is now crystal clear!

Rogue Engineering refuses to compromise with "lever substitution" as a method of short shift kit development. Rather than using actual test vehicles for their products, some companies actually dig through OEM factory parts diagrams to determine which factory levers can be substituted with others. This "lever substitution" method of introducing product is unacceptable. These shift kits have been developed and perfected through years of experience in proven short shifter technology, by Co-Founder, Ben Liaw. As longtime BMW enthusiasts know, Ben was single-handedly responsible for introducing and developing the idea of affordable, BMW factory-like, short shift kits for late model BMWs (BL/SS for those young enough to remember!). 

Rogue Engineering idea of a short shift kit is not substituting levers in place of factory ones just because "they fit". Throughout the 80s until recently, BMW was notorious for using only a few specific shifter levers for their manual transmission vehicles. For other companies, making just a few "replacement levers" and offering them in place of those factory part numbers was an easy way of calling it a short shift kit. Unfortunately, for those companies, BMW started using many different part numbers making it more difficult to just "swap in a lever".

Rogue Engineering only develops it's short shift kit with test vehicles in their facility, testing numerous prototypes, offering others to test it before settling on its final design.

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.

78mm Diameter with fitment for M12 nuts/bolts.

Powerflex's new transfer case bushing insert is made from polyurethane and is designed to reinforce your OE rubber transfer case bushing. This helps to stiffen the bushing and limits excessive movement of the transfer case. This Performance bushing is rated at 80A durometer, which is moderately stiffer than your OE bushing's rubber. This is perfect for someone who occasionally tracks their BMW and is looking for better performance at the cost of a bit more NVH. As this bushing is 80A durometer, a moderate amount of extra NVH should be expected.

The Powerflex Rear Diff Front Mount Bushing for the BMW E46 3 Series and Z4 is a premium upgrade designed to enhance the stability and performance of the drivetrain. Here’s an alternative description:

  • High-Performance Polyurethane: Powerflex bushings are made from advanced polyurethane, which is significantly more durable than standard rubber. This material resists wear, deformation, and the effects of heat, oil, and contaminants, making it a long-lasting solution for high-performance applications.

  • Purpose: The rear differential front mount is subjected to high levels of stress during acceleration and cornering. Over time, the stock rubber bushing can degrade, causing excessive movement in the differential. The Powerflex bushing eliminates this movement, allowing for improved drivetrain control and reducing unwanted flex.

  • Key Features:

    • Enhanced Rigidity: By replacing the softer OEM rubber with Powerflex’s stiffer polyurethane, this bushing minimizes differential movement under load, resulting in improved throttle response and sharper handling.
    • Improved Longevity: Unlike the factory rubber mounts, which can crack and wear out over time, the polyurethane construction ensures long-lasting performance and reliability.
    • Performance-Oriented Design: Powerflex’s bushing is engineered to handle the increased demands of spirited driving and track use, offering better control without sacrificing comfort.
  • Benefits:

    1. Improved Power Transfer: Reducing differential movement helps direct more power to the wheels, improving acceleration and delivering a more connected driving feel.
    2. Better Handling and Stability: With less flex in the differential, the car becomes more stable, particularly during cornering and high-speed driving, enhancing overall handling precision.
    3. Durable and Maintenance-Free: Polyurethane bushings are resistant to common automotive chemicals, heat, and road debris, providing a set-and-forget solution that lasts longer than rubber components.
  • Fitment: This bushing is designed as a direct replacement for the front mount of the rear differential in BMW E46 3 Series and Z4 models. It installs easily, without requiring modifications, and offers an immediate improvement in drivetrain response.

In summary, the Powerflex Rear Diff Front Mount Bushing is an essential upgrade for BMW E46 and Z4 drivers who want to improve drivetrain rigidity, reduce flex, and enhance overall performance. This bushing provides a durable, long-lasting solution that’s perfect for both street and track use, delivering better power transfer and handling.

The best way to gain a prominent advantage over the competition is to do it with the MFactory Metal Plate Limited Slip Differential. The smooth consistent distribution of power to the wheels with the MFactory Plate LSD puts the power to the ground and maximizes your vehicle's traction. This 1.5-way differential works similarly to a 2-way in that it provides torque transfer during both acceleration and deceleration. However, the advantage over a 2-way is that it requires less force to lock the differential. This means that it will allow for different wheel speeds, like when cornering. A 1.5-way differential is typically the best option for track or street use, as it keeps from having one tire skipping or dragging.
