Flywheels for BMW Z3 (1996-2002)

Clear BMW chassis

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.

A lightweight aluminum flywheel is a great way to increase throttle response and free up horsepower by reducing drivetrain loss. Factory flywheels are built to minimize engine and transmission vibrations, making them heavier and requiring more energy to make them spin. An aluminum flywheel can save lots of weight over the stock steel unit - sometimes over 50%. While the dampening effect of the stock flywheel is reduced, most enthusiasts would agree that the increase in performance is well worth it. In addition, the lighter flywheel allows the engine to spin more freely, improving throttle response. This JB Racing lightweight aluminum flywheel kit and is designed to be used with the included factory clutch, making replacement and service easy and inexpensive, especially compared to specialized racing clutches. It also preserves the driveability of your car on the street, and enthusiasts tolerant of a mild to moderate NVH increase will be especially taken with this setup. In addition, the JB Racing flywheel can be easily rebuilt with a new clutch contact surface, allowing you to enjoy faster revs and superior response for many years to come. Stock Flywheel Weight: 27 lbs. JB Racing Lightweight Aluminum Flywheel: 9 lbs.

This lightened steel flywheel is specifically designed (and approved) for use in Grand-Am road racing but can also be used as a mild street upgrade if a full aluminum lightweight flywheel is not called for. The Grand-Am flywheel is 20% lighter than stock to meet the rules for the GS and ST classes.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. A lightweight flywheel does away with the dual mass design and its additional mass so 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. The engine revs much 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.

Grand-Am approved this flywheel to be used with a factory E36 M3 clutch. This opens up a lot of clutch and pressure plate options but we typically used this with a stock Sachs OEM clutch kit. This makes replacement clutch components easy to source and inexpensive when compared to specialized racing clutches.

Lightweight 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.

If being used on a 330i 6-speed or Z4 6-speed an additional pilot bearing hub is required. Select your appropriate model and transmission from the list below.
