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.

Elevate your MINI driving experience with this essential Short Shift Kit that significantly enhances performance. However, many short shift kit upgrades necessitate leaving out the assembly box cover due to the extended ball linkage. Unfortunately, this leaves the assembly box internals exposed to external elements, resulting in dirt accumulation and increased interior air and noise pollution.

But fear not! NM has the solution: a modified OEM ABS cover equipped with a powder-coated aluminum 'hump.' This unique design effectively covers the cut-out, sealing the assembly box interior entirely. The kit comes complete with the blue cover and necessary hardware.

MINI F54 to F57 NM Short Shift Adapter is a must-have upgrade for your MINI, offering enhanced driving performance with a simple installation. This adapter, crafted from 100% CNC machined T303 stainless steel, installs on the lower end of the factory shifter, reducing travel by 20mm and retaining the OEM shift knob and its position. The NM Short Shift Adapter ensures smooth and precise shift engagement without notchy travel. Enjoy a quicker and more responsive shifting experience with this easy-to-install adapter, which comes with full step-by-step instructions.

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
