The Spec Stage 3 clutch kit stands out with its carbon semi-metallic 6-puck sprung hub disc, celebrated for exceptional drivability, extended longevity, and remarkable torque capacity. This kit is tailor-made for street and race cars that demand a forceful yet street-friendly engagement and substantial torque capability. For those acquainted with "puck" style pressure plates, the Spec kit aims to deliver racing-style performance while ensuring a smoother street experience.

The double-sprung hub with spring cover reliefs enhances flexibility, reducing harsh shifts. Additionally, all kit components undergo heat treatment for heightened durability, ensuring optimal performance even in high-pressure, high-temperature scenarios.

Key Features:

• High clamp pressure plate
• Carbon-Graphite friction material
• High-torque sprung hub and disc assembly
• Includes bearing and tool kit

Advanced Clutch Technology (ACT) designs, engineers and develops products by leveraging decades of track and performance street experience. Advanced CAD, FEA simulation, and CAM tools help ensure highly optimized performance, reliability, and repeatability. These key advantages are produced by combining the best engineering and design methodologies with the latest in materials and manufacturing techniques.

ACT clutch kits stand unequaled in terms of consistent pedal feel, high torque capacity, long wear life and durability. In-house manufacturing is critical in tuning components specifically to each individual application while maintaining the predictable ACT pedal feel across the entire catalog.

This clutch kit features a Heavy Duty pressure plate and a Performance Street Rigid clutch disc.

The heavy duty pressure plate included offers a 20-50% clamp load increase, stock-moderate  pedal feel, and heat treated diaphragms for increased strength and performance.

Next in this kit is the Performance Street Rigid clutch disc. This disc is an unsprung, rigid disk that is suited for aggressive street and moderate racing applications. The disc pad features high quality organic friction material with a high copper content for improved heat transfer and a steel backed lining for increased strength in burst load circumstances. This organic clutch disc has a significantly higher torque capacity than a stock disc but due to its rigid nature, may suffer from slightly increased spline wear over time.

Clutch Kit Specs:

• Torque Rating: 440 ft/lbs
• 45% torque capacity increase over stock!
• Type of Disc: Street
• 26-count spline
• Spline Size: 1-3/8" inch
• Disc Weight: 2.3 lbs
• Pressure Plate Weight: 10.2 lbs
• 1 year Warranty from retail purchase date!

• Choice of sprung or rigid hub for flexibility
• Ideal for street and track/off-road use

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

Results: Sharper throttle response, more precise rev-matching, and a more engaging driving experience
