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.

Excessive driveline vibration is caused by one of a few things, but more than likely, it is the mounts in your vehicle. They keep your engine and transmission secure for more positive shifting and driveline triangulation as well as absorbing vibration. If any of these are occuring in your BMW, it's time to examine your mounts.

This flywheel replaces the stock original single-mass flywheel and should only be used with the corresponding 'single-mass' clutch kit. According to BMW the single mass flywheel was installed in all 325i up to 12/86 production date but we have seen some later cars with a single-mass flywheel. The age of the car almost guarantees one or more clutch replacements and possibly a change to the original flywheel as well. You may not know which flywheel is currently installed until the flywheel cover or the transmission is removed.

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).

The JB Flywheel includes the pilot bearing mounted in the flywheel hub, just like the factory configuration.

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
1997-1998 Z3 BMW Z3 2.8

This lightweight aluminum flywheel w/ Heavy Duty "sprung-hub" clutch package is the best-engineered solution for E46 325 and 330 models with the 6-speed transmission, Z4 2.5/3.0, and Z4 M Roadster and M Coupe. Instead of picking a clutch from another car that may or may not work at all, the engineers at JB Racing have taken all of the guess work out of this upgrade and incorporated a Sachs sport sprung-hub clutch with the correct pressure plate and combined it with their most-popular aluminum lightweight flywheel. The Sachs HD clutch disc has a sprung hub to minimize noise and vibration and organic linings to give the feel and engagement of a stock clutch. Mixing and matching of the incorrect clutch, pressure plate, and flywheel components can lead to inconsistent engagement and feel -- why make your clutch feel worse?

In addition, the Sachs HD pressure plate will clamp with greater force -- allowing approximately 350 ft-lbs of torque, which makes it an obvious upgrade from the stock clutch kit. And with the aluminum flywheel weight savings is substantial over the stock dual-mass flywheel - which allows your motor to spool up faster and transmit more HP to the ground.

Because Sachs is an OE supplier to most German cars, replacement parts are just a phone call away. This kit uses the stock throw-out bearing (included in the price).

This flywheel replaces the stock original single-mass flywheel and should only be used with the corresponding 'single-mass' clutch kit. According to BMW the single mass flywheel was installed in all 325e up to 5/86 production date but we have seen some later cars with a single-mass flywheel. The age of the car almost guarantees one or more clutch replacements and possibly a change to the original flywheel as well. You may not know which flywheel is currently installed until the flywheel cover or the transmission is removed.

The ultimate in a racing flywheel and clutch! This was developed for use in our E36 and E46 World Challenge Touring Cars. The combined weight of the clutch and flywheel is only 11lbs!!!

This multi-disc (2 or 3 disc setups) offer a minimal flywheel mass (enough to include a factory ring gear for the starter) and a small 5.5" clutch assembly rated to 500hp. By saving as much weight as possible less energy is used in simply spinning the flywheel/clutch assembly and that means a lot more power and torque is available at the drive wheels. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines and this is among the most advanced and lightest racing clutch kits available for your BMW race car.

The JB Ultra-Light Performance racing clutch is available in 2-disc or 3-disc setups. We used the 5.5"/140mm size in our Touring Cars but larger sizes are available too. This is a turn-key racing clutch and flywheel kit that you don't have to engineer or spec yourself. This is the same clutch setup we used when winning the 2003 and 2004 Touring Car Championships - the quality and performance is unquestionable. That series also employed standing starts at each race and this clutch setup performed flawlessly with nearly a full season of racing on them before needing a change.

JB Ultra-Light flywheels include:

precision CNC machined aluminum flywheel

zero-balanced up to 10,000 RPM

replaceable hardened steel clutch friction surface

Helicoil threaded inserts

high-strength grade 10.9 hardware

multi-disc racing clutch with Performance racing pressure plate

JB Racing throw-out bearing with custom bobbin
This is a true racing clutch and will not function as a street-able clutch at all. It behaves as an on/off switch with no slippage allowed. Extreme care must be used when driving on to trailers and around the paddock. But when driven correctly the life span of this clutch is amazing - we could get a full season of racing a 300hp M54 from this clutch setup including standing starts at every race! Replacement clutch components and flywheel rebuilding are available.

A properly adjusted clutch stop is required for use with this clutch kit.

Stock Flywheel + Clutch Weight = 45+lbs
JB Ultra-Light Flywheel & Clutch Weight = 11lbs

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).

The JB flywheel includes ignition trigger wheel.

This flywheel replaces the stock original dual-mass flywheel and should only be used with the corresponding 'dual-mass' clutch kit. According to BMW the dual mass flywheel was installed in all 325/325e from 5/86 on but we have seen some later cars with a single-mass flywheel. The age of the car almost guarantees one or more clutch replacements and possibly a change to the original flywheel as well. You may not know which flywheel is currently installed until the flywheel cover or the transmission is removed.

Stock Flywheel Weight = 27.5lbs
JB Flywheel Weight = 10.0lbs

This item fits the following BMWs:
1984-1988 E30 BMW 325e 325es (with dual mass flywheel)
