Lightweight Flywheel! Dual To Single Mass Conversion

The factory dual-mass flywheel in your N14 & W11-powered MINIs were engineered with comfort in mind - reducing drivetrain vibration, smoothing shifts, and enhancing overall refinement. But this comes at a price: a hefty 27-28 lbs. of rotational mass that mutes throttle response, slows acceleration, and makes rev-matching less precise. It's also prone to failure in tuned or modified setups and expensive to replace.

Enter the ECS Tuning Lightweight Flywheels, a performance-driven upgrade designed to shed unnecessary weight and deliver a more visceral driving experience. Weighing in at just 17 & 18.5 lbs., nearly 10 lbs. lighter than stock, these single-mass flywheels sharpen throttle response, quickens acceleration, and enhances clutch feedback. It's the perfect upgrade for MINI enthusiasts who demand more engagement and performance.


Nearly 10 lbs. lighter than the OEM flywheel!
