The factory BMW S55 dual-mass flywheel is engineered with comfort in mind, catering to the luxury-oriented expectations of the brand’s driving experience. Its design focuses on dampening drivetrain vibrations, smoothing out gear transitions, and minimizing harshness during operation. However, this refinement costs valuable performance. The dual-mass flywheel adds a substantial 26.5 lbs of rotational mass to the drivetrain, which significantly hinders throttle response and makes rev-matching feel sluggish and disconnected. Moreover, dual-mass flywheels are notorious for being a weak link in modified or high-performance builds and can prove costly to replace when they inevitably fail.
Our Single-Mass Lightweight Flywheel Conversion addresses all of these shortcomings with a purpose-built, lightweight, single-mass design that prioritizes performance. Weighing in at only 18.5 lbs., this design significantly reduces rotational mass, allowing your S55 to achieve its true motorsport potential!
Features & Benefits:
Precision machined from 4140 HT heat-treated chromoly steel for exceptional toughness, even wear properties, and increased durability.
Material quality promotes even wear across the entire friction surface, prolonging component lifespan.
Heat treated to HRC 28-32, tempered to relieve stress and improve dimensional stability.
Hardness improves component wear characteristics.
Black oxide coated for corrosion resistance on non-friction surfaces.
Precision balanced to exceed OEM specification (G16 spec to 175g-mm).
SFI 1.1 certified to ensure safe operation under extreme operating conditions.
Specifically designed to work with S55 OE-architecture clutches.
Optimized step height maximizes clutch clamp load and offers a prolonged service life.
Performance:
10 lbs. lighter than the factory BMW flywheel!
OEM Dual-Mass: 26.5 lbs.
Turner Motorsport Single-Mass: 18.5 lbs.
Faster revs
Improved throttle response and acceleration
Allows for a more engaging driving experience and delivers a feeling of direct connection
Installation:
Flywheel Hardware: For added peace of mind, apply Blue or Orange Loctite when installing factory flywheel bolts that do not come with pre-applied threadlocker.

From the factory, the E46 M3 featured a dual-mass flywheel and self-adjusting clutch kit. While this provided an easy, comfortable driving experience, it lacks the durability and performance features of an upgraded clutch and flywheel kit. ECS Tuning's all-new S54 performance clutch kit is designed to address these issues. Featuring a full-face clutch disc and heavy-duty pressure plate, this kit offers increased power-holding capability, exceptional pedal feel, and superior durability.
The factory dual-mass flywheel weighs 24.2 lbs. This heavyweight component favors dampened vibrations and smooth gear changes—not performance. The 16.5 lb. E34 M5 flywheel designed by ECS omits the bulky dual-mass design for a single-mass, chromoly steel flywheel. For the performance-minded enthusiast, this translates to quicker RPM changes, easier "heel-toe" downshifts, and improved acceleration.
Engineered in-house with the enthusiast in mind, this is the perfect option for those wanting a lightweight flywheel and performance clutch, without the heavy pedal feel commonly associated with aggressive clutch kits. The ECS S54 performance clutch and lightweight flywheel are designed to accommodate all conditions: from Sunday drives through the country to the abuse of the track. No matter your driving style or ability, this is the flywheel and clutch kit for you.
PART DESIGN
ECS S54 Performance Clutch Kit:
Compatible with any performance flywheel that is designed to accept an E34 M5 architecture clutch Sprung-hub clutch disc Includes ECS performance pressure plate, performance clutch disc, throwout bearing, pilot bearing, alignment tool, and all flywheel and pressure plate hardware ECS Single-Mass Lightweight Flywheel:
Eliminates the factory dual-mass flywheel for: Improved throttle response Improved acceleration Lower replacement cost Hardened 4140 Chromoly Steel for excellent engagement feel and wear resistance Zinc-plated for added corrosion resistance Weighs in at just 16.5 lbs! SFI tested and certified to ensure safe operation under all conditions Why is SFI testing and certification important?
The SFI Foundation, Inc. (SFI) is a non-profit organization established to issue and administer standards for the quality assurance of specialty performance and racing equipment. SFI certification indicates a flywheel has been certified using industry-standard SFI Spec 1.1 standards by an independent testing body to ensure the quality of both design and materials for flywheels utilized in competitive motorsports.
Having successfully passed SFI certification, this flywheel has an individual SFI serial number found in a laser etching, and on an affixed sticker. This certification means the ECS-engineered flywheel is safe and reliable during the rigors of competitive racing; it's also safe and reliable for years and years of street use.
