Clear BMW chassis

Please ensure your correct model is selected

These heavy-duty clutch kits use aluminum lightweight flywheels with sport clutch components to give your clutch the grip and clamping force it needs to cope with high torque upgrades. Our kits were developed through racing programs by companies affiliated with our own race team - JB Racing, Sachs Sport, OS Giken, and UUC Motorwerks. JB Racing is the leader in aluminum lightweight flywheel upgrades. They are direct replacements for the stock dual-mass flywheels with steel contact surfaces and computer balanced to 14,000 RPM. JB has partnered with Sachs to spec sport/HD clutch discs and pressure plates that work seamlessly with their aluminum flywheels. The result is a clutch/flywheel upgrade package that functions a lot like the original clutch combo with near-stock levels of effort and engangement but with a much higher torque capacity. Don't let the clutch be your weak link in a highly tuned car!

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

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.
