BMW Drivetrain Parts for BMW E21 320i M10 1.8L

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.

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.

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).

Stock Flywheel Weight = 16.5lbs
JB Flywheel Weight = 8lbs

1974-1976 2002 BMW 2002

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.
