The JB Racing Lightweight Aluminum Flywheel is a high-performance racing flywheel designed specifically for BMW E30, E36, and Z3 models. This flywheel is compatible with M40/M42/M44 engines, and is made from high-grade billet aluminum, making it both lightweight and durable, delivering exceptional performance and reliability in the most demanding racing conditions.
With a weight of just 9 pounds, this JB Racing flywheel significantly reduces rotational mass, resulting in faster acceleration, improved throttle response, and better overall performance. The aluminum construction also allows for improved heat dissipation, which helps to prevent clutch slippage and other performance issues during high-stress driving conditions.
The flywheel features a single-piece design with a high-friction surface that provides exceptional grip and reduced rotational mass. This allows for quicker rev-matching and smoother shifts, giving drivers a competitive edge on the track. The flywheel is also balanced to within 0.5 grams for smooth operation and minimal vibration.
Installation of the JB Racing Lightweight Aluminum Flywheel is easy and straightforward, as it is designed to be a direct replacement for the OEM flywheel in BMW E30, E36, and Z3 models with M40/M42/M44 engines. It is compatible with a wide range of high-performance clutch systems and can be used in both street and racing applications.
Overall, the JB Racing Lightweight Aluminum Flywheel is a top-of-the-line racing component that is sure to impress even the most discerning racers. Its lightweight design, exceptional performance, and ease of installation make it an excellent choice for anyone looking to take their BMW E30, E36, or Z3 racing performance to the next level. Whether you're a professional racer or a weekend warrior, this flywheel will help you achieve your best lap times and overall racing performance.

Tech Notes:
We recommend pairing a lightweight clutch with a ‘spring hub’ style Clutchmasters clutch. This will offer better power holding during sporty driving, and the sprung hub helps reduce clutch chatter and noise when used with a single mass flywheel like the JB Racing pieces.
Important install note from JB Racing:
Non-A/C equipped cars have a different flywheel than A/C equipped cars. These were sold outside of the US market. If you have a Non-A/C version, you must purchase the A/C-Equipped clutch for use with the JBR replacement flywheel.
