Flywheels for BMW 1 Series

Clear BMW chassis

Please ensure your correct model is selected

The factory BMW flywheel is a 2 piece design that mitigates vibration and creates a comfortable driving experience. A single piece aftermarket flywheel will allow the engine to rev quicker and gives shifting a much more direct and mechanical feel. This also makes clutch modulation on spirited takeoffs much easier and more predictable and is a must if you plan on tracking or competing in your BMW.

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).

This JB flywheel replaces the stock flywheel and can be used with either the stock 228mm or stock 240mm clutch discs. Depending on the model you may have either clutch size in your car but this flywheel is compatible with both. You can install a 240mm clutch as a mild upgrade.

Stock Flywheel Weight = 24-31.0lbs
JB Flywheel Weight = 12.0lbs

This is the stock twin mass flywheel for the N55 engine used in the E82 135i, E9X 335, F3x 335/435, and F10 535i. It's manufactured by OEM supplier LuK. Sachs recommends a new dual mass flywheel (DMF) on every other clutch replacement. There are several indicators for replacing the flywheel: damage to the clutch contact plate (from a severely worn clutch disc), grease leaking from inside (overheating), build-up of clutch material on the contact plate (excessive slipping and overheating), and failure of the internal damping system.

The dampening system uses rubber or coil springs to absorb driveline vibrations. Through age, excessive heat, and aggressive use the rubber loses its resilience and the metal springs lose their strength and become brittle. If the clutch and flywheel have become overheated the internal grease may break down as well. A DMF failure can be massive and catastrophic, not to mention dangerous as bits of metal and rubber fling themselves through the transmission bellhousing. Heat and aggressive driving will accelerate the wear so race and track cars should have their stock flywheels replaced at regular intervals or with any new clutch. Even normal street cars should plan for a new flywheel if it has high mileage.

DMF wear can only be checked with the transmission and clutch removed. If you can rotate the outer flywheel more than 20mm in either direction then it should be replaced.

A new pilot bearing (roller bearing) is included, pre-installed in the flywheel hub.

This item fits the following BMWs with the single turbo N55 engine and manual transmission:

This is the stock OE BMW twin mass flywheel for the N54 engine in later E82 135i, E9X 335i, E60 535i, and Z4 35i (cars with 6-bolt mounting hub). Sachs recommends a new dual mass flywheel (DMF) on every other clutch replacement.
