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.

Looking to upgrade your clutch disc? This Sachs Performance clutch disc is a great option. Allowing for higher torque and horsepower, this disc is perfect for aggressive track applications such as endurance racing, clubsport, autocross, hill climbing and 1/4 mile racing.

Supplying countless brands with OE parts and offering one of the widest selection of OEM replacement parts, they are known for their exceptionally high quality products. You can purchase these performance parts with confidence, knowing they will resist heavy wear and tear for much longer than most other aftermarket options.

This is an OEM LuK stock twin mass flywheel for the N52 non-turbo engine in the 128i, 325i/328i/330i, 525i/528i/530i, and Z4 30i. It's manufactured by OEM supplier LuK. Sachs recommends a new dual mass flywheel (DMF) on every other clutch replacement. There are several indicators for replacing the flywheel: damage to the clutch contact plate (from a severely worn clutch disc), grease leaking from inside (overheating), build-up of clutch material on the contact plate (excessive slipping and overheating), and failure of the internal damping system.

The dampening system uses rubber or coil springs to absorb driveline vibrations. Through age, excessive heat, and aggressive use the rubber loses its resilience and the metal springs lose their strength and become brittle. If the clutch and flywheel have become overheated the internal grease may break down as well. A DMF failure can be massive and catastrophic, not to mention dangerous as bits of metal and rubber fling themselves through the transmission bellhousing. Heat and aggressive driving will accelerate the wear so race and track cars should have their stock flywheels replaced at regular intervals or with any new clutch. Even normal street cars should plan for a new flywheel if it has high mileage.

DMF wear can only be checked with the transmission and clutch removed. If you can rotate the outer flywheel more than 20mm in either direction then it should be replaced.

A new pilot bearing (roller bearing) is included, pre-installed in the flywheel hub.
