BMW Performance Clutch Kits & Parts

These heavy-duty clutch kits use aluminum lightweight flywheels with sport clutch components to give your clutch the grip and clamping force it needs to cope with high torque upgrades. Our kits were developed through racing programs by companies affiliated with our own race team - JB Racing, Sachs Sport, OS Giken, and UUC Motorwerks. JB Racing is the leader in aluminum lightweight flywheel upgrades. They are direct replacements for the stock dual-mass flywheels with steel contact surfaces and computer balanced to 14,000 RPM. JB has partnered with Sachs to spec sport/HD clutch discs and pressure plates that work seamlessly with their aluminum flywheels. The result is a clutch/flywheel upgrade package that functions a lot like the original clutch combo with near-stock levels of effort and engangement but with a much higher torque capacity. Don't let the clutch be your weak link in a highly tuned car!

A lightweight aluminum flywheel is a great way to increase throttle response and free up horsepower by reducing drivetrain loss. Factory flywheels are built to minimize engine and transmission vibrations, making them heavier and requiring more energy to make them spin. An aluminum flywheel can save lots of weight over the stock steel unit - sometimes over 50%. While the dampening effect of the stock flywheel is reduced, most enthusiasts would agree that the increase in performance is well worth it. In addition, the lighter flywheel allows the engine to spin more freely, improving throttle response. This JB Racing lightweight aluminum flywheel kit and is designed to be used with the included factory clutch, making replacement and service easy and inexpensive, especially compared to specialized racing clutches. It also preserves the driveability of your car on the street, and enthusiasts tolerant of a mild to moderate NVH increase will be especially taken with this setup. In addition, the JB Racing flywheel can be easily rebuilt with a new clutch contact surface, allowing you to enjoy faster revs and superior response for many years to come. Stock Flywheel Weight: 27 lbs. JB Racing Lightweight Aluminum Flywheel: 9 lbs.

Dual-mass flywheels allow for fluid-feeling clutch engagements and offer a more luxurious feel than single-mass flywheels. However, with these benefits come significant drawbacks. Dual-mass flywheels are expensive, with the cost of replacement often being double or triple that of converting to a single-mass flywheel. Single-mass flywheels can be resurfaced, eliminating the need to replace them with the next clutch service, something that is not recommended with dual-mass flywheels as they contain a rubber section that is more failure-prone in high-mileage applications. Single-mass flywheels lack the complexity of dual-mass flywheels, making them inherently more reliable. Dual-mass flywheels contain a rubber damper or hub that will, like all rubber components, wear out with time. Also, Many enthusiasts prefer to eliminate BMW's "Self Adjusting Clutch", which has been known to provide an unpredictable, inconsistent engagement point. Valeo's conversion kit has been designed to maintain nearly identical clutch and flywheel weight, ideal for keeping the clutch quiet and easy to drive.

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

This JB Racing lightweight aluminum flywheel kit and is designed to be used with the included factory clutch, making replacement and service easy and inexpensive, especially compared to specialized racing clutches. It also preserves the driveability of your car on the street, and enthusiasts tolerant of a mild to moderate NVH increase will be especially taken with this setup. In addition, the JB Racing flywheel can be easily rebuilt with a new clutch contact surface, allowing you to enjoy faster revs and superior response for many years to come. A lightweight aluminum flywheel is a great way to increase throttle response and free up horsepower by reducing drivetrain loss. Factory flywheels are built to minimize engine and transmission vibrations, making them heavier and requiring more energy to make them spin. An aluminum flywheel can save lots of weight over the stock steel unit - sometimes over 50%. While the dampening effect of the stock flywheel is reduced, most enthusiasts would agree that the increase in performance is well worth it. In addition, the lighter flywheel allows the engine to spin more freely, improving throttle response.

Aluminum flywheels are much lighter than the stock steel flywheel and that produces better throttle response and more available horsepower to the wheels for faster acceleration. The JB Racing aluminum flywheels are a direct replacement for the stock flywheel and work with stock clutch components for an easy upgrade with very little downside.

This lightened steel flywheel is specifically designed (and approved) for use in Grand-Am road racing but can also be used as a mild street upgrade if a full aluminum lightweight flywheel is not called for. The Grand-Am flywheel is 20% lighter than stock to meet the rules for the GS and ST classes.Modern flywheels are built with additional components and features that are designed to dampen and minimize vibrations from the engine and transmission. As a result they have become bloated in weight and that means more energy is used up just making the flywheel spin. A lightweight flywheel does away with the dual mass design and its additional mass so more energy can be diverted to where it counts most - moving the car. The flywheel and clutch is one of the first areas that engine builders address when making the rotating assembly lighter for race engines. The dampening effect is just not needed on cars that are focused on performance.

In addition to releasing more power to the wheels, the lighter flywheel allows the engine to spin more freely, which improves throttle response. The engine revs much faster than before. With the engine spinning easier the power band comes up much sooner. The stock steel flywheel feels lazy in comparison. There is a driving adjustment required to get used to how much faster the engine revs but that's not really a downside.

Grand-Am approved this flywheel to be used with a factory E36 M3 clutch. This opens up a lot of clutch and pressure plate options but we typically used this with a stock Sachs OEM clutch kit. This makes replacement clutch components easy to source and inexpensive when compared to specialized racing clutches.

Lightweight flywheels are considered 'single-mass' flywheels because they do not have the same dampening designs as an original 'dual-mass' flywheel. With a single-mass design more noise and vibration may be noticeable. There are steps you can take to minimize the noise - heavier weight transmission oil and clutch discs with anti-rattle springs (sprung-hub clutch). In addition to the standard replacement clutches, we also sell Sachs Performance sprung hub clutches that also work with the JB flywheels.

If being used on a 330i 6-speed or Z4 6-speed an additional pilot bearing hub is required. Select your appropriate model and transmission from the list below.
