Turner Motorsport Lightweight N54 Flywheel & Upgraded Clutch Kit

Unlock the full potential of your N54-powered BMW with our performance-driven clutch and flywheel kit. Designed to enhance daily drivability while delivering increased power handling and improved throttle response, this kit is the ultimate upgrade for enthusiasts seeking more from their vehicle.

Why Choose This Kit?
This setup features the Turner Lightweight N54 Flywheel, precision-engineered for quicker acceleration, faster rev-matching, and a more responsive driving experience. Paired with an upgraded OE clutch from the high-performance 335is and F10 550i(V8 Bi-Turbo), this combo is capable of handling over 500 ft-lbs of torque while maintaining smooth, factory-like engagement and durability.

The factory dual-mass flywheel may prioritize smoothness and efficiency, but it comes at the cost of responsiveness and is prone to failure in high-performance applications. The Turner Lightweight Flywheel solves these issues with a single-mass design that strikes the perfect balance between comfort, performance, and reliability making it ideal for both daily driving and spirited track use.

Upgrade for 135i/335i/535i models from the 335is! Featuring a heavy-duty clutch with more holding power and a stock-like pedal feel. Excellent solution for If your clutch is slipping, or the engagement isn't what it used to be, it's time for a replacement. Slipping clutches won't allow your BMW to accelerate properly and can pose problems under a load such as going up large inclines. Also, a worn clutch can cause less precise and engaging shifts. By replacing your clutch you will restore performance and driving pleasure.

This clutch is an excellent upgrade for non 335is/550i/650i models. It features a more heavy-duty clutch disc and more holding power with stock-like pedal effort.

Transform your driving experience with this Turner Motorsport clutch and flywheel kit - engineered for power, performance, and everyday reliability.

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.

This kit from Valeo is a simple way to easily convert your stock dual mass flywheel clutch system to a single mass system.

Dual mass flywheels allow for fluid-feeling clutch engagements and offer a more luxurious feel than single-mass flywheels. However, with these benefits come significant drawbacks. Why convert from a dual-mass flywheel to a single-mass flywheel?

Cost: Dual-mass flywheels are expensive, with the cost of replacement often times being double or triple than that of converting to a single-mass flywheel.
Serviceability: Single-mass flywheels can be resurfaced, eliminating the need to replace with the next clutch service. - something that is not recommended with dual-mass flywheels, as they contain a rubber section that is more failure-prone in high mileage application.
Simplicity: Single-mass flywheels lack the complexity of dual-mass flywheels, making them inherently more reliable. Dual-mass flywheels contain a rubber damper or hub that will, like all rubber components, wear out with time.
Pedal Feel: Many enthusiasts prefer to eliminate BMW's "Self Adjusting Clutch", which has been known to provide an unpredictable, inconsistent engagement point.
Driveability: Valeo's conversion kit has been designed to maintain nearly identical clutch and flywheel weight, ideal for keeping the clutch quiet and easy to drive.
