Stock rubber flex discs allow for a slight amount of give, especially under heavy acceleration and, depending on the amount of force applied, could potentially tear or split. This slight flex/give can prevent instantaneous transfer of force to the wheels, making accelerations unpredictable, or even lead to your vehicle being stuck on the side of the track. To combat this, IRP's Performance Flex Disc was developed. Made of CNC machined aluminum, this flex disc won't actually flex, and the polyurethane bushings will only provide a enough give to dampen some vibrations and prevent damaging the transmission. This is perfect for high torque applications such a drag cars and dedicated track cars that want immediate response and long term reliability.
78mm Diameter with fitment for M12 nuts/bolts.

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
Kit Includes:
ECS N14/N18 Lightweight Performance Flywheel
South Bend Stage Two “Daily” Clutch Kit
Pilot Bearing
Throw-Out Bearing
Clutch Alignment Tool
(6) Genuine MINI Flywheel Bolts

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.
**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.
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.
