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.

When it's time to replace your car's clutch, you face a crucial decision: upgrade or stick with stock? In many cases, upgrading is the preferred choice, especially when you pair the right clutch with a single mass flywheel. The secret to achieving the perfect blend of performance and driving experience lies in selecting a sprung hub clutch. This option allows you to enjoy the advantages of a single mass flywheel while eliminating issues like noise, vibration, and harshness (NVH), ensuring an outstanding driving performance.
SPEC's Stage 2 clutch features a full faced pure Kevlar disc complete with steel backing. This lining offers outstanding drivability like the Stage 1 kit, with an increased torque capacity and a longer life. The hub is double sprung with built-in spring reliefs for flexibility, along with heat treatment for added strength and durability. This clutch is best served in any situation from daily driven on the street, to drag or autocross racing events.

Installation Details:
Advanced Clutch Technology (ACT) designs, engineers and develops products by leveraging decades of track and performance street experience. Advanced CAD, FEA simulation, and CAM tools help ensure highly optimized performance, reliability, and repeatability. These key advantages are produced by combining the best engineering and design methodologies with the latest in materials and manufacturing techniques.
ACT clutch kits stand unequaled in terms of consistent pedal feel, high torque capacity, long wear life and durability. In-house manufacturing is critical in tuning components specifically to each individual application while maintaining the predictable ACT pedal feel across the entire catalog.
This clutch kit features an Xtreme pressure plate, a Performance Street sprung clutch disc, and an XACT Streetlite Flywheel.
Their Xtreme pressure plate offers a 50-120% clamp load increase, moderate to heavy pedal feel, and is recommended for high performance street and racing applications. All diaphragms went through a four stage heating process for increased strength and unparalleled performance.
Next in this kit is the Performance Street clutch disc. This is the most popular sprung clutch disc and features high quality organic friction material with a high copper content for improved heat transfer and a steel backed lining for increased strength in burst load circumstances. This organic clutch disc has a significantly higher torque capacity than a stock disc but still retains a long life span and operates quietly and reliably.

This clutch kit features an Xtreme pressure plate and an R6 racing clutch disc.
Their Xtreme pressure plate offers a 50-120% clamp load increase, moderate to heavy pedal feel, and is recommended for high performance street and racing applications. All diaphragms went through a four stage heating process for increased strength and unparalleled performance.
Next in this kit is the R6 racing clutch disc. This disc is an unsprung, rigid disc with 6 pads that is best suited for drag and road racing and handles heat better thanks to its increased surface contact area versus the 4 pad version of this disc, the R4. The R6 pads are composed of ceramic friction materials and the disc has a chome-moly hub that is heat treated for additional strength under high load engagements. Over stock, this disc is much better for faster shifting and significantly higher torque loads. Unlike the stock disc, this racing disk has a slightly shortened life span due to its rigid design and pad composition. This in turn is offset thanks to its fast, aggressive engagement for track use.
Clutch Kit Specs:

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.

This clutch kit features a Xtreme pressure plate, an G6 racing clutch disc, and an XACT Streetlite Flywheel.
Their Xtreme pressure plate offers a 50-120% clamp load increase, moderate to heavy pedal feel, and is recommended for high performance street and racing applications. All diaphragms went through a four stage heating process for increased strength and unparalleled performance.
The G6 clutch disc is a sprung, 6-pad racing disc that is recommended for high horsepower street and race us and is better at handling high heat than the 4-pad disc. Its material composition is high quality, ceramic friction materials and a heavy duty torsional dampening springs that are rate for this clutch disc's size and expected uses. It has an increased torque capacity, and is better for faster shifting with its low weight and inertia. Being a racing disc, it has good durability and its ceramic composition allows for high heat tolerances. It also has a fast, aggressive engagement in comparison to standard street-use clutch discs.
The XACT Streetlite Flywheel is their most popular flywheel as it is great for both street and drag racing. It allows your engine to rev quicker, giving you increased throttle response, and is considerably lighter than your stock flywheel thanks to its light single-mass design, all while still being very durable!
