BMW Drivetrain Parts

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.

The DCT transmission in your BMW is nothing short of incredible and exhilarating, but also astronomically expensive to replace. BMW has been labeling fluids as "lifetime" for quite some time now, and as enthusiasts and owners have learned over the years, there simply is no fluid that lasts a lifetime. When you do decide to replace the transmission fluid, make sure you also replace your transmission filter to prevent any and all debris from getting pulled through and causing damage.

GA8HP 8 speed automatic transmission. Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. This item fits the following BMWs: E71,E89 Z4,F06,F10,F12,F13,F15,F16,F22,F25 X3,F26 X4,F30,F31,F32,F33,F34,F36

As Used on Project E36 M3
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). In addition to the standard replacement clutches, we also sell Sachs Performance sprung hub clutches that also work with the JB flywheels.

This flywheel replaces the stock original single-mass flywheel and should only be used with the corresponding 'single-mass' clutch kit. According to BMW the single mass flywheel was installed in all 325i up to 12/86 production date but we have seen some later cars with a single-mass flywheel. The age of the car almost guarantees one or more clutch replacements and possibly a change to the original flywheel as well. You may not know which flywheel is currently installed until the flywheel cover or the transmission is removed.

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 be rebuilt too with a new clutch contact surface.

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).

If your MINI is only for competition use - autocross, time trial, or racing - this OS Giken LSD may be a better option than the standard 1.5-way unit. This race-spec LSD was developed over several seasons of competitive autocross. It uses a new high pressure ring for quicker response time and faster lockup. This makes it ideal for quick transitions and rapid on/off throttle motions typically encountered on the track. It's a one-way lockup so the car stays predictable under braking and gives the driver more feedback. For street use we prefer the normal 1.5-way setup because it's more progressive during lockup.

The biggest shortcoming of any MINI is not the lack of power - it's being able to put all of its useable power to the ground! The Cooper S is basically a one-wheel drive car and sending 200+ hp through that one tire does not live up to its full potential. A limited-slip differential is essential to any highly-tuned FWD car. The OS Giken Super-Lock is one of the most advanced clutch-type differentials on the market, and a favorite of autocrossers and road racers. The OS LSD for the MINI features ten clutch discs for a smooth and progressive lockup. By putting all of your available power to the ground you're at an instant advantage over the stock open-type differential. You'll be able to power through corners and on rough surfaces instead of uselessly spinning a wheel. Understeer is reduced by giving more bite to the tire that has the most traction. With an LSD in your MINI Cooper S you'll wonder why it wasn't first on your list to begin with (or why MINI/BMW left it out in the first place...).

The MNI OS Giken LSD uses a special 80W250 fluid that must be purchased separately.

These key advantages are produced by combining the best engineering and design methodologies with the latest in materials and manufacturing techniques.

ACT clutch kits stand unequaled in terms of consistent pedal feel, high torque capacity, long wear life and durability. In-house manufacturing is critical in tuning components specifically to each individual application while maintaining the predictable ACT pedal feel across the entire catalog.

This clutch kit features an Xtreme pressure plate, a Performance Street sprung clutch disc, and an XACT Streetlite Flywheel.

Their Xtreme pressure plate offers a 50-120% clamp load increase, moderate to heavy pedal feel, and is recommended for high performance street and racing applications. All diaphragms went through a four stage heating process for increased strength and unparalleled performance.

Next in this kit is the Performance Street clutch disc. This is the most popular sprung clutch disc and features high quality organic friction material with a high copper content for improved heat transfer and a steel backed lining for increased strength in burst load circumstances. This organic clutch disc has a significantly higher torque capacity than a stock disc but still retains a long life span and operates quietly and reliably.

 

Clutch Kit Specs:

  • Torque Rating: 520 ft/lbs

BMW E36 328i, Z3 2.8 JB Racing Lightweight Aluminum Flywheel offers a significant performance upgrade by replacing the heavy stock steel flywheel with a much lighter aluminum version. This JB Racing flywheel is designed to deliver faster acceleration, improved throttle response, and enhanced overall performance for your BMW.

The modern stock flywheels are burdened with additional components meant to dampen vibrations, which unfortunately adds unnecessary weight. The JB Racing aluminum flywheel, weighing just 10.0 lbs compared to the stock 25.0 lbs, eliminates this excess mass, allowing more power to reach the wheels and reducing the energy wasted on spinning the flywheel. Engine builders prioritize lightweight flywheels when optimizing race engines for maximum efficiency, and the difference is especially noticeable in how quickly the engine revs and reaches its power band.

This JB Racing lightweight flywheel is a direct replacement for the stock flywheel and is compatible with the factory BMW organic clutch. This compatibility ensures that you can use standard replacement clutches, making maintenance simple and cost-effective. The flywheel can also be resurfaced for a fresh contact surface, so there’s no need to buy a new one when it’s time to replace the clutch.

While single-mass aluminum flywheels like this one may result in slightly more noise and vibration compared to dual-mass designs, this can be managed with heavier transmission oil and sprung hub clutches, such as the Sachs Performance clutch available through Turner Motorsport.

  • Faster acceleration: Reduces the rotational mass for quicker engine response.
  • Improved throttle response: Engine revs more freely and builds RPM faster.
  • Enhanced performance: More power delivered to the wheels for better driving dynamics.
  • Cost-effective maintenance: Compatible with factory BMW organic clutches and can be resurfaced.
  • Direct replacement: Easy upgrade with no modifications required.

Vehicle Compatibility:

  • 1996-1999 E36 BMW 328i, 328is, 328ic
  • 1997-1998 Z3 BMW Z3 2.8

This flywheel replaces the stock original single-mass flywheel and should only be used with the corresponding 'single-mass' clutch kit. According to BMW the single mass flywheel was installed in all 325e up to 5/86 production date but we have seen some later cars with a single-mass flywheel. The age of the car almost guarantees one or more clutch replacements and possibly a change to the original flywheel as well. You may not know which flywheel is currently installed until the flywheel cover or the transmission is removed.

Advanced Clutch Technology (ACT) designs, engineers and develops products by leveraging decades of track and performance street experience. Advanced CAD, FEA simulation, and CAM tools help ensure highly optimized performance, reliability, and repeatability. These key advantages are produced by combining the best engineering and design methodologies with the latest in materials and manufacturing techniques.

ACT clutch kits stand unequaled in terms of consistent pedal feel, high torque capacity, long wear life and durability. In-house manufacturing is critical in tuning components specifically to each individual application while maintaining the predictable ACT pedal feel across the entire catalog.

This clutch kit features a Heavy Duty pressure plate and a G6 racing clutch disc.

**Must be used with an ACT XACT Streetlite Flywheel, Part number: 600315**

The heavy duty pressure plate included offers a 20-50% clamp load increase, stock-moderate  pedal feel, and heat treated diaphragms for increased strength and performance.

Next in this kit is the G6 racing clutch disc. This disc is a sprung, 6-pad disc that is suited for high horsepower road and track style racing and is also better at handling higher heat versus the 4-pad version of this disc, the G4. The G6 pads are composed of ceramic friction materials and the disc has a chome-moly hub that is heat treated for additional strength under high load engagements. Also featured are heavy duty torsional springs that are rated for the clutch kit's expected uses. Over stock, this clutch kit has a much higher torque capacity and is better for quick shifting thanks to lower weight and inertia. Despite its ceramic racing style pads, this disc has great durability. In turn, these pads provide higher heat tolerances and faster, more aggressive clutch engagements.

The ultimate in a racing flywheel and clutch! This was developed for use in our E36 and E46 World Challenge Touring Cars. The combined weight of the clutch and flywheel is only 11lbs!!!

This multi-disc (2 or 3 disc setups) offer a minimal flywheel mass (enough to include a factory ring gear for the starter) and a small 5.5" clutch assembly rated to 500hp. By saving as much weight as possible less energy is used in simply spinning the flywheel/clutch assembly and that means a lot more power and torque is available at the drive wheels. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines and this is among the most advanced and lightest racing clutch kits available for your BMW race car.

The JB Ultra-Light Performance racing clutch is available in 2-disc or 3-disc setups. We used the 5.5"/140mm size in our Touring Cars but larger sizes are available too. This is a turn-key racing clutch and flywheel kit that you don't have to engineer or spec yourself. This is the same clutch setup we used when winning the 2003 and 2004 Touring Car Championships - the quality and performance is unquestionable. That series also employed standing starts at each race and this clutch setup performed flawlessly with nearly a full season of racing on them before needing a change.

JB Ultra-Light flywheels include:
  • precision CNC machined aluminum flywheel
  • zero-balanced up to 10,000 RPM
  • replaceable hardened steel clutch friction surface
  • Helicoil threaded inserts
  • high-strength grade 10.9 hardware
  • multi-disc racing clutch with Performance racing pressure plate
  • JB Racing throw-out bearing with custom bobbin
    This is a true racing clutch and will not function as a street-able clutch at all. It behaves as an on/off switch with no slippage allowed. Extreme care must be used when driving on to trailers and around the paddock. But when driven correctly the life span of this clutch is amazing - we could get a full season of racing a 300hp M54 from this clutch setup including standing starts at every race! Replacement clutch components and flywheel rebuilding are available.

    A properly adjusted clutch stop is required for use with this clutch kit.

    Stock Flywheel + Clutch Weight = 45+lbs
    JB Ultra-Light Flywheel & Clutch Weight = 11lbs

    The M Dynamic limited slip unit on the M3 is designed to be a pure street car differential. It's simply not up to the rigors of professional or amateur racing. The OS Giken Super Lock LSD is giant step up in from a stock M3 lsd unit. It's ready for the extreme conditions of racing, offers 100% progressive locking capability, and is able to do this while operating smoothly and quietly. It's use of advanced technologies that make it perfect for both street cars AND pro race cars... and everything in between. We're excited to be carrying the OS Giken LSD unit in our performance catalog, as we've been using them in our own Championship winning M3 race cars.

    OS Giken incorporated revolutionary new ideas when developing the their own limited slip diff, utilizing their accumulated racing knowledge and experience and over 4 years of development. Their design uses an unprecedented number of friction plates (up to 28 total!) for better locking force, better engagement/disengagement, and less generated heat. The end result of their efforts is the OS Giken's OS Super Lock LSD which offers incredible durability and reliability on street and track driven BMWs. The use of highest quality materials, precise machining, forged gears and sound engineering makes this LSD durable and reliable enough for road racing performance (which we can personally vouch for!). This is such a great design, in that it can be used in any situation -- whether it's for a street car, or a 100% Professional race car. Zero break-in required. Super smooth and quiet engagement, and 100% progressive locking capability. Professional installation is recommended.

    This Limited Slip Differential Unit fits the following BMWs:
    2001-2006 E46 M3 coupe & convertible
    2008-2013 E9X M3 coupe & convertible
    1991-1995 E34 M5 sedan

    ACT clutch kits stand unequaled in terms of consistent pedal feel, high torque capacity, long wear life and durability. In-house manufacturing is critical in tuning components specifically to each individual application while maintaining the predictable ACT pedal feel across the entire catalog.

    This clutch kit features an Xtreme pressure plate and an R6 racing clutch disc.

    Their Xtreme pressure plate offers a 50-120% clamp load increase, moderate to heavy pedal feel, and is recommended for high performance street and racing applications. All diaphragms went through a four stage heating process for increased strength and unparalleled performance.

    Next in this kit is the R6 racing clutch disc. This disc is an unsprung, rigid disc with 6 pads that is best suited for drag and road racing and handles heat better thanks to its increased surface contact area versus the 4 pad version of this disc, the R4. The R6 pads are composed of ceramic friction materials and the disc has a chome-moly hub that is heat treated for additional strength under high load engagements. Over stock, this disc is much better for faster shifting and significantly higher torque loads. Unlike the stock disc, this racing disk has a slightly shortened life span due to its rigid design and pad composition. This in turn is offset thanks to its fast, aggressive engagement for track use.

    Clutch Kit Specs:

    • Torque Rating: 665 ft/lbs
    • 117% torque capacity increase over stock!
    • Type of Disc: Racing
    • 26-count spline
    • Spline Size: 1-3/8" inch

    This lightweight aluminum flywheel w/ Heavy Duty "sprung-hub" clutch package is the best-engineered solution for E46 325 and 330 models with the 6-speed transmission, Z4 2.5/3.0, and Z4 M Roadster and M Coupe. Instead of picking a clutch from another car that may or may not work at all, the engineers at JB Racing have taken all of the guess work out of this upgrade and incorporated a Sachs sport sprung-hub clutch with the correct pressure plate and combined it with their most-popular aluminum lightweight flywheel. The Sachs HD clutch disc has a sprung hub to minimize noise and vibration and organic linings to give the feel and engagement of a stock clutch. Mixing and matching of the incorrect clutch, pressure plate, and flywheel components can lead to inconsistent engagement and feel -- why make your clutch feel worse?

    In addition, the Sachs HD pressure plate will clamp with greater force -- allowing approximately 350 ft-lbs of torque, which makes it an obvious upgrade from the stock clutch kit. And with the aluminum flywheel weight savings is substantial over the stock dual-mass flywheel - which allows your motor to spool up faster and transmit more HP to the ground.

    Because Sachs is an OE supplier to most German cars, replacement parts are just a phone call away. This kit uses the stock throw-out bearing (included in the price).

    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.

    Every design is thoroughly researched and tested prior to release to guarantee their products meet and exceed the customer's expectations. Careful attention is payed to factors such as engine torque, maximum RPM, drive type (FWD, RWD, AWD), and the type of driving being done, such as street, sport, track events, racing, etc. ACT's clutch kits are competitively priced, often with  specifications greater than competitor's and at a higher quality.

    This clutch kit features a Xtreme pressure plate, an G6 racing clutch disc, and an XACT Streetlite Flywheel.

    Their Xtreme pressure plate offers a 50-120% clamp load increase, moderate to heavy pedal feel, and is recommended for high performance street and racing applications. All diaphragms went through a four stage heating process for increased strength and unparalleled performance.

    The G6 clutch disc is a sprung, 6-pad racing disc that is recommended for high horsepower street and race us and is better at handling high heat than the 4-pad disc. Its material composition is high quality, ceramic friction materials and a heavy duty torsional dampening springs that are rate for this clutch disc's size and expected uses. It has an increased torque capacity, and is better for faster shifting with its low weight and inertia. Being a racing disc, it has good durability and its ceramic composition allows for high heat tolerances. It also has a fast, aggressive engagement in comparison to standard street-use clutch discs.

    The XACT Streetlite Flywheel is their most popular flywheel as it is great for both street and drag racing. It allows your engine to rev quicker, giving you increased throttle response, and is considerably lighter than your stock flywheel thanks to its light single-mass design, all while still being very durable!

    Clutch Kit Specs:

    • Torque Rating: 465 ft/lbs
    • 52% torque capacity increase over stock!
    • Type of Disc: Street
    • 10-count spline

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.

    This flywheel replaces the stock original dual-mass flywheel and should only be used with the corresponding 'dual-mass' clutch kit. According to BMW the dual mass flywheel was installed in all 325/325e from 5/86 on but we have seen some later cars with a single-mass flywheel. The age of the car almost guarantees one or more clutch replacements and possibly a change to the original flywheel as well. You may not know which flywheel is currently installed until the flywheel cover or the transmission is removed.

    Stock Flywheel Weight = 27.5lbs
    JB Flywheel Weight = 10.0lbs

    BM9-HDG4 kit features ACT's most popular Heavy Duty pressure plate. ACT Heavy Duty pressure plates use an exclusive diaphragm design to increase clamp load, reduce deflection and maximize clutch life. All diaphragms endure a four-stage, heat-treating process for unparalleled performance. ACT pressure plates have precision cover stampings to provide rigidity and consistency. ACT's 4-pad spring-centered race disc features a spring-center to properly damp torsional vibrations for quieter operation and resist failure even under harsh conditions. ACT spring retainers utilize wraparound spring windows and thicker retainer stampings to provide spring support, reduce stress concentrations, and increase strength and reliability. With the 4-pad spring-centered race disc, engagement is harsher, but shifting is faster. ACT's 4-pad spring-centered race disc is well-suited for smaller disc sizes in smaller engines.
