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.

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.

Soft bushings are the enemy of launching hard, and keeping your drivetrain together. The BMW Transfer Case bushings are notoriously soft, and that is the opposite of what you want when launching a car hard. You can replace the bushing with a solid one, but this is time-consuming usually requires lowering or removing the transfer case, and results in a lot of added NVH. The best path is simply to reduce the amount of flex of the factory bushing so you keep the nice manners when cruising around town, and at idle, but when its time to the launch the transfer case cannot move as it could without the insert. These come as a set of two with 2 bolts to keep them in place. Install time once you get to them is about 2-3 minutes. Could not be easier. Put some lube on them, push them in, and tighten the screws. These are a MUST for high-power G8X, and F9X X3/X4M Builds. All platforms they fit are below. Features: 6061- T6 aluminum construction Easy to install Fully reversible Do not add NVH

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).

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

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.

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.

    AutoTecknic was established in 2000 and has since become one of the largest manufacturers and distributors of carbon fiber parts and accessories for a wide variety of manufacturers. Autotecknic has designed gear selector trim for the G05 X5, G06 X6, and G07 X7 composed of 3k twill weave carbon fiber. Includes guide for installation. Dry carbon fiber's name also comes from its manufacturing process. Dry carbon fiber is formed by using a "pre-preg" or impregnated piece of carbon materials. This piece of carbon is first placed into a mold, and then into a sealed vacuum (autoclave) to properly cure. This particular method creates the least amount of waste and forms a lighter version of carbon than the “wet” method. The autoclave vacuuming process of making dry carbon means that there are fewer pinholes and virtually no air pockets that form in the carbon. Dry carbon is the highest quality version of carbon fiber products that are produced.

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.

    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).

    Z4 M Sport Clutch and Flywheel Applications:
    2006-2008 E85 Z4, E86 Z4 Z4 M Roadster, Z4 M Coupe

    Looking to upgrade your stock differential to the BMW M Performance differential? This kit includes the M Performance limited slip diff plus all the hardware necessary to install the diff in your BMW! What exactly does an LSD do you ask? Well, without an LSD your car is effectively only 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, which is typically 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.

    VTT noticed a hole in the F9X X3/4M market for a high-quality, lightweight, NVH-friendly, and easy-to-install Diff Lock Down kit to improve diff stability under launching, and hard cornering. So we did something about it and went to work on a very innovative design that 100% positively locks the diff down from movement, while shielding it from adding a ton of NVH, and can be used with the stock diff, and subframe bushings. This design uses existing mounting points on the vehicle, you do NOT have to remove the subframe or the Diff to install. Simply remove 4 differential bolts, drill two holes in the subframe slightly bigger, install two M8 riv-nuts, and install the lockdown, you do not even have to move the exhaust. A typical install can be 30-45 minutes for someone who is experienced working on vehicles, an hour or two if you like taking it slow. Features: Lightweight 1.5 lbs for the entire lockdown plate Uses FOUR connection points on the Diff, and three on the subframe for the ultimate in positive diff location, this will stop all diff movement on launch, saving your guibos, etc 100% Billet construction from 6061-T6 aluminum Anodized in 3 colors for corrosion resistance, a long-lasting finish, and good looks The subframe does NOT have to be removed for installation Uses all 12.9 grade hardware Does not add excessive NVH Positively locks down the diff to eliminate all unwanted movement under launches, acceleration, cornering, etc.

    VTT now offers the ONLY easy-to-install, plug-and-play xDrive controller on the market. This device will allow you to turn off and on your xDrive capability from the driver's seat with a remote. While other options do exist such as X-Delete, or an in-dash gauge, one is a very slow process and is not viable to use as a way to do a burnout at the drag strip, and the other is a very expensive, AND very intrusive device that requires removal of most of the dash, and installing a gauge. VTT's solution takes 30 seconds to install once you gain access to the underside of the vehicle, and can be removed just as easily.
