Performance Clutch Kits

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!

Featuring a sprung-hub center section for use with a single-mass flywheel

The factory dual-mass flywheel in MINI N14 and N18 engines is engineered for comfort, minimizing drivetrain vibrations and smoothing out gear transitions. However, that comfort comes at a price—28.3 lbs. of rotational mass that dulls throttle response, slows acceleration, and hampers precise rev-matching. Dual-mass flywheels are also notoriously prone to failure under high-performance or tuned driving conditions, and their replacement costs can be steep.

The ECS Performance Lightweight Flywheel Kit eliminates these compromises with a precision-engineered, single-mass flywheel that delivers true enthusiast-grade performance. Weighing in at just 18.8 lbs, this flywheel sheds nearly 10 lbs. of rotating mass compared to OEM—instantly sharpening throttle response, improving clutch feel, and delivering quicker acceleration that transforms the driving dynamics of your MINI.

Performance-Oriented Design: This flywheel is specifically engineered to work with OE and aftermarket unsprung clutch discs. While dual-mass setups provide damping on stock vehicles, switching to a single-mass flywheel with an unsprung disc introduces more direct engagement—ideal for spirited daily driving or track-ready builds. Expect a more aggressive, performance-focused clutch feel.
