The factory BMW S65 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 27 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 19 lbs., this design significantly reduces rotational mass, allowing your S65 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).
Specifically designed to work with S65 OE-architecture clutches.
Optimized step height maximizes clutch clamp load and offers a prolonged service life.
Performance:

8 lbs. lighter than the factory BMW flywheel!
OEM Dual-Mass: 27 lbs.
Turner Motorsport Single-Mass: 19 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.

An SFI approved single mass flywheel is recommended for this application to get optimal performance. This clutch system is designed for the racing climate. The pressure plate is precision balance for vibration free operation at high RPM. The pressure plate fulcrum is altered for a positive disengagement and a quick shift. The disc is engineered with a Dual Damped design to provide accurate control when accelerating through corners. The friction material is a hybrid using a full face Feramic (Sintered Iron) lining on the flywheel side and a high metal content Organic lining on the pressure plate side. Engagement is positive yet buffered due to the high graphite content unique to Feramic facings.
