The factory dual-mass flywheel in your MINI N14 was built with comfort in mind—absorbing drivetrain vibrations and smoothing shifts—but at the cost of performance. Weighing in at a hefty 28.3 lbs., the OEM flywheel adds excessive rotational mass, dulling throttle response, slowing acceleration, and complicating precise rev-matching. Worse yet, it's known to be unreliable in modified or tuned setups and expensive to replace when it fails.
This single-mass design from ECS Tuning weighs just 18.8 lbs. It cuts nearly 10 lbs. of rotational weight to significantly enhance throttle response, acceleration, and overall driving feel. Built for durability and spirited driving, it's the ultimate upgrade for enthusiasts who want to make the most of every gear change.
Key Features:
Precision CNC-machined from 4140 HT Chromoly Steel: Ensures outstanding toughness, consistent wear, and long-term durability.
Heat Treated and Tempered: Achieves HRC 28-32 for improved strength, stress relief, and dimensional stability—even at elevated temperatures.
Black Oxide Coated: Resists corrosion for long-lasting protection and a professional finish.
Precision Balanced: Exceeds OEM standards (G16, 175 g-mm) to ensure smooth, safe operation at all RPMs.
SFI 1.1 Certified: Tested and approved for extreme use—track or street.
Direct Fit for OE N14 Clutch Kits: Maintains compatibility with factory-style components for hassle-free installation.

The factory dual-mass flywheel in W11-powered MINI Coopers was designed with comfort in mind—minimizing drivetrain vibration and delivering smoother shifts. However, this focus on refinement comes at a performance cost. The hefty 27 lbs. of rotational mass dulls throttle response, slows acceleration, and makes rev-matching more difficult. Dual-mass flywheels are also known to be less reliable in tuned or modified setups and can be expensive to replace when they fail.
ECS Tuning developed their Lightweight Single-Mass Flywheel to address these issues with a performance-focused alternative. Weighing in at just 17 lbs., this flywheel sheds nearly 10 lbs. of rotating mass compared to the OEM unit—transforming throttle response, acceleration, and clutch feel for a more engaging and dynamic driving experience.
