Turner Motorsport Lightweight N54 Flywheel & Upgraded Clutch Kit

Unlock the full potential of your N54-powered BMW with our performance-driven clutch and flywheel kit. Designed to enhance daily drivability while delivering increased power handling and improved throttle response, this kit is the ultimate upgrade for enthusiasts seeking more from their vehicle.

Why Choose This Kit?
This setup features the Turner Lightweight N54 Flywheel, precision-engineered for quicker acceleration, faster rev-matching, and a more responsive driving experience. Paired with an upgraded OE clutch from the high-performance 335is and F10 550i(V8 Bi-Turbo), this combo is capable of handling over 500 ft-lbs of torque while maintaining smooth, factory-like engagement and durability.

The factory dual-mass flywheel may prioritize smoothness and efficiency, but it comes at the cost of responsiveness and is prone to failure in high-performance applications. The Turner Lightweight Flywheel solves these issues with a single-mass design that strikes the perfect balance between comfort, performance, and reliability making it ideal for both daily driving and spirited track use.

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.

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.
