BMW Drivetrain Parts for MINI

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.

Key Features:

Lightweight Construction: Sheds nearly 10 lbs. of rotating mass for faster revs and improved acceleration

4140 Chromoly Steel: Heat-treated to HRC 28–32 for outstanding strength, wear resistance, and dimensional stability

Precision-Balanced: Exceeds OEM G16 specification (175 g-mm) for smooth, high-RPM operation

Black Oxide Coating: Offers corrosion resistance and a professional finish

OE-Compatible Fitment: Designed to work seamlessly with N14 architecture clutch kits

SFI 1.1 Certified: Proven safe and reliable under extreme operating conditions

Optimized Step Height: Ensures maximum clutch clamping force and long-term durability

Performance Gains:

OEM Dual-Mass Flywheel Weight: 28.3 lbs

ECS Single-Mass Flywheel Weight: 18.8 lbs

Weight Savings: Nearly 10 lbs of reduced rotational mass
