The JB Lightweight Aluminum Racing Flywheel is a high-performance racing flywheel designed specifically for BMW transmissions that go with the S38 engine. Made from high-grade billet aluminum, this flywheel is both lightweight and durable, delivering exceptional performance and reliability in the most demanding racing conditions.
With a weight of just 8.5 pounds, this 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 Flywheel is easy and straightforward, as it is designed to be a direct replacement for the OEM flywheel in BMW transmissions that go with the S38 engine. 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 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 S38 engine 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.
Benefits:
- Weighs 8.5 lbs compared to 19+ lbs stock flywheel
- Reduced rotating mass and moment of inertia for quicker acceleration and deceleration
- Replaceable heavy duty friction surface and OEM ring gear
- Ready to bolt in
- Hardware
- Accepts OEM M3 clutch disc
Tech Notes:
- While the transmission is open for service, its a great time to take care of your clutch: Using a solid flywheel like this, we recommend requesting a sprung-disc clutch for street use to help keep clutch/flywheel noise to a minimum.
- These flywheels are intended for use to replace the US market M6 & M5s with the single mass flywheels. If you are replacing a Euro- Dual-mass flywheel, you must also use a US Spec (single mass) Clutch kit.
