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.

Upgrade for 135i/335i/535i models from the 335is! Featuring a heavy-duty clutch with more holding power and a stock-like pedal feel. Excellent solution for If your clutch is slipping, or the engagement isn't what it used to be, it's time for a replacement. Slipping clutches won't allow your BMW to accelerate properly and can pose problems under a load such as going up large inclines. Also, a worn clutch can cause less precise and engaging shifts. By replacing your clutch you will restore performance and driving pleasure.

This clutch is an excellent upgrade for non 335is/550i/650i models. It features a more heavy-duty clutch disc and more holding power with stock-like pedal effort.

Forged, Double Tempered and Super Sub-Zero treated for unsurpassed toughness
Proprietary Nitride surface treatment for increased surface hardness

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: 24-31 lbs.

JB Racing Lightweight Aluminum Flywheel: 12 lbs.

Enhance Your Car's Performance with the Perfect Clutch-Flywheel Combination

When it's time to replace your car's clutch, you face a crucial decision: upgrade or stick with stock? In many cases, upgrading is the preferred choice, especially when you pair the right clutch with a single mass flywheel. The secret to achieving the perfect blend of performance and driving experience lies in selecting a sprung hub clutch. This option allows you to enjoy the advantages of a single mass flywheel while eliminating issues like noise, vibration, and harshness (NVH), ensuring an outstanding driving performance.
