ECS Tuning R52 R53 W11 Lightweight Single Mass Flywheel

The factory dual-mass flywheel in your W11-powered MINI was engineered with comfort in mind—reducing drivetrain vibration, smoothing shifts, and enhancing overall refinement. But this comes at a price: a hefty 27 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 Flywheel—a performance-driven upgrade designed to shed unnecessary weight and deliver a more visceral driving experience. Weighing in at just 17 lbs., nearly 10 lbs. lighter than stock, this single-mass flywheel sharpens throttle response, quickens acceleration, and enhances clutch feedback. It’s the perfect upgrade for MINI enthusiasts who demand more engagement and performance.

**This flywheel is to match with a factory type or aftermarket NON Dampened clutch kit!** MINIs factory set up engagement is dampened by the dual mass flywheel. This will be a little more aggressive engagement of the clutch over the stock factory set up as they system in not dampened!! Can be used from daily to the track days.
