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). In addition to the standard replacement clutches, we also sell Sachs Performance sprung hub clutches that also work with the JB flywheels.

BMW E36 328i, Z3 2.8 JB Racing Lightweight Aluminum Flywheel offers a significant performance upgrade by replacing the heavy stock steel flywheel with a much lighter aluminum version. This JB Racing flywheel is designed to deliver faster acceleration, improved throttle response, and enhanced overall performance for your BMW.

The modern stock flywheels are burdened with additional components meant to dampen vibrations, which unfortunately adds unnecessary weight. The JB Racing aluminum flywheel, weighing just 10.0 lbs compared to the stock 25.0 lbs, eliminates this excess mass, allowing more power to reach the wheels and reducing the energy wasted on spinning the flywheel. Engine builders prioritize lightweight flywheels when optimizing race engines for maximum efficiency, and the difference is especially noticeable in how quickly the engine revs and reaches its power band.

This JB Racing lightweight flywheel is a direct replacement for the stock flywheel and is compatible with the factory BMW organic clutch. This compatibility ensures that you can use standard replacement clutches, making maintenance simple and cost-effective. The flywheel can also be resurfaced for a fresh contact surface, so there’s no need to buy a new one when it’s time to replace the clutch.

While single-mass aluminum flywheels like this one may result in slightly more noise and vibration compared to dual-mass designs, this can be managed with heavier transmission oil and sprung hub clutches, such as the Sachs Performance clutch available through Turner Motorsport.

Faster acceleration: Reduces the rotational mass for quicker engine response.
Improved throttle response: Engine revs more freely and builds RPM faster.
Enhanced performance: More power delivered to the wheels for better driving dynamics.
Cost-effective maintenance: Compatible with factory BMW organic clutches and can be resurfaced.
Direct replacement: Easy upgrade with no modifications required.

Vehicle Compatibility:

1996-1999 E36 BMW 328i, 328is, 328ic

Many racing series and event organizers are requiring 5 or 6-point harnesses in their events now. Attaching the anchor points to the seat base is a desired alternative to drilling holes in your floor and carpet*. This set includes the 6-point anchor to attach to the Macht Schnell floor mount as well as side attachments for either a bolt-in or snap-in harness.

* - note that most racing harness manufacturers will advise that drilling through the floor is the best method for mounting harnesses. This allows you to locate the mount in the ideal location and angle to fit your driving position. The proper installation is paramount to ensure the harness works correctly in an impact.

Sold per seat.

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.
