BMW Drivetrain Parts for MINI

Clear BMW chassis

Please ensure your correct model is selected

Building your perfect BMW is more than just adding horsepower and stiff suspension. Your drivetrain needs attention in order to deliver power effectively. Most BMWs feature comfortable clutch discs, heavy flywheels, long shifter throws, and open differentials. The drivetrain transmits power to the wheels, but can also be a source of power loss when it is designed for comfort rather than performance. Everything on this page will help you improve your power delivery and driving experience by providing custom Limited Slip Differentials, Short Shift Conversions, Performance Clutch Discs, Lightweight Flywheels, and anything else your BMW needs to be the perfect driving experience.

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.

Performance Benefits:

Substantial Weight Reduction

​OEM Flywheel: 28.3 lbs.

ECS Lightweight Flywheel: 18.8 lbs.

Net Savings: Nearly 10 lbs.

Faster Revving and Sharper Throttle Response: Reducing rotational mass translates into a more dynamic and responsive driving experience.

Improved Clutch Engagement and Longevity: Optimized step height delivers better clamp load and extends service life.

Ideal for Modified MINIs: Built to handle increased power and spirited driving with confidence.

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.

Key Features:

Manufactured from 4140 Chromoly Steel
Heat-treated and tempered for exceptional strength, wear resistance, and thermal stability.
Optimized Hardness (HRC 28–32)
Ensures consistent performance and durability under extreme conditions.
Precision-Balanced to G16 Standard (175 g-mm)
Exceeds OEM balance requirements for smooth, high-RPM operation.
Black Oxide Finish
Provides effective corrosion resistance and a sleek appearance.
SFI 1.1 Certified
Validated for safe use in high-performance and racing environments.
Direct Fit
Engineered to work seamlessly with OE-style clutch kits designed for the W11 engine architecture.
Performance Benefits:

OEM Flywheel Weight: 27 lbs
ECS Lightweight Flywheel Weight: 17 lbs
This significant weight reduction results in:

Sharper throttle response
Faster engine revs and acceleration
Improved clutch engagement and feel
Increased performance potential for modified vehicles
