BMW Drivetrain Parts for BMW E21 320i M10 1.8L

Clear BMW chassis

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.

As BMWs age, and from spirited use, the shift linkage in the manual transmission will become worn. This selector rod joint is one of the main pieces in the shift linkage but is often overlooked when installing a new shifter or rebuilding the original linkage. This knuckle is the piece that connects the linkage to the internals of the transmission, therefore, it's vital in completing smooth and crisp shifts. Our selector rod kit includes the pieces to replace the transmission selector rod joint and restore its action to a new feel.

In addition to helping restore shifting feel, this piece is required in many short shift kits and selector rod upgrades. The original joint on your car may be the wrong size or shape to work with the new selector rod.

This kit includes part numbers 25117503525 - selector rod joint, 23411466134 shift linkage pin, 4 x 25111220439 washer .

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

Over time, these units can wear out and develop an annoying squeak when the pedal is pressed. Responsible for transferring fluid to the slave cylinder to engage and disengage the clutch, a worn unit can affect pedal feel and performance. Swap yours out and eliminate that pesky squeaky piston for good.
