Please ensure your correct model is selected

These heavy-duty clutch kits use aluminum lightweight flywheels with sport clutch components to give your clutch the grip and clamping force it needs to cope with high torque upgrades. Our kits were developed through racing programs by companies affiliated with our own race team - JB Racing, Sachs Sport, OS Giken, and UUC Motorwerks. JB Racing is the leader in aluminum lightweight flywheel upgrades. They are direct replacements for the stock dual-mass flywheels with steel contact surfaces and computer balanced to 14,000 RPM. JB has partnered with Sachs to spec sport/HD clutch discs and pressure plates that work seamlessly with their aluminum flywheels. The result is a clutch/flywheel upgrade package that functions a lot like the original clutch combo with near-stock levels of effort and engangement but with a much higher torque capacity. Don't let the clutch be your weak link in a highly tuned car!

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.

Stock Flywheel Weight = 25.0lbs
JB Flywheel Weight = 20.0lbs

Upgrade the whole driving experience of your car with a single mass clutch and flywheel conversation paired with new upgraded engine and transmission mounts. These street durometer mounts are 70 and 75 durometer for an improved but not too harsh driving experience. This clutch and flywheel upgrade features a slightly heavier pedal feel with smooth engagement, paired with your upgraded drivetrain mounts you are sure to have confidence in how sturdy your car drives!

Our performance clutch and flywheel kit utilizes an upgraded ECS E34 M5 clutch kit with our in-house engineered flywheel to fit all M5x and S5x motors with a 5-speed transmission. By eliminating the dual-mass flywheel and replacing it with a single-mass we are able to eliminate the slack and extra weight of the flywheel for a quicker throttle response and acceleration. Our upgraded clutch kit utilizes all the best features of the original M5 clutch with an upgraded pressure plate and clutch disc, with the new clutch you have a better, more engaged clutch pedal feel, engagement, and longevity.

Whether you're replacing a worn-out clutch or upgrading for increased power handling, this E34 M5 clutch and flywheel kit offers a reliable solution for enhanced pedal feel, power capacity, and overall driving satisfaction.

Paired with a modified geometry flywheel, the E34 M5 style clutch is ideally suited for most E36, E46, and others using the same powertrain. It checks all the boxes for essential clutch replacement features. While some aftermarket options may address slipping issues and worn-out clutches, they often sacrifice pedal feel, providing little to no resistance. A soft clutch not only kills the driving experience of your BMW but also reduces confidence when pushing the car to its limits.

On the contrary, you might be in the market for an upgraded clutch to handle your modified engine/forced induction builds. You go from an OE or aftermarket clutch option that has a lackluster and soft pedal feel to the complete opposite side of the spectrum, a very stiff clutch that grabs like an on-and-off switch making the clutch a pain almost undrivable on the street resulting in your favorite car turning into your least favorite car to drive.

The E34 M5 clutch and flywheel kit balances performance with practicality, ensuring a satisfying driving experience whether you're maintaining your BMW or preparing it for increased power demands.

70A durometer rating - slightly stiffer than stock for improved shifting quality and driveline performance. Constructed of 304 stainless steel with bonded and constrained polyurethane. The transmission mounts in your car play a critical role in your suspension. With this in mind, the stock mounts have been known to experience failures causing over-revving, mis-shifts, and in extreme cases, even chassis damage. Combat this issue with upgraded polyurethane transmission mounts from ECS Tuning. Designed with the street and track in mind, we've got you covered no matter your driving style. Fears of torn mounts are a thing of the past; a mechanical interlock feature makes these mounts ideal even for high-torque, forced-induction applications. Engine Mounts - 75A Durometer

Keep your engine securely mounted with our solid, non-fluid-filled mounts. Our ECS 75A Durometer engine mounts are custom-made in-house by our leading R&D department. These mounts result from countless hours of research and testing to establish the best possible bushing design to minimize engine vibration and driveline deflection while maximizing strength. ECS Tuning's primary goal was to achieve an economical, durable & compliant ride while maximizing performance. After putting down thousands of real-world test miles on multiple vehicles, we've done just that. With exposure to heat and elements, your motor mounts will break down with increasing age. A secure mount* is vital to reduce drivetrain vibration and transfer as much horsepower to the wheels as possible. These mounts are an upgrade for non-M E36/E46 owners seeking a stiffer mount without sacrificing comfort and ride quality.
