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.

The DCT transmission in your BMW is nothing short of incredible and exhilarating, but also astronomically expensive to replace. BMW has been labeling fluids as "lifetime" for quite some time now, and as enthusiasts and owners have learned over the years, there simply is no fluid that last a lifetime.

This DCT service kit that takes the guesswork out of a fluid change . No need to track down the correct fluid and plugs, simply open the box, and get the job done the correct way. By servicing your DCT transmission, you will be assured that old, broken down fluid won't cause a several thousand dollar nightmare. We recommend this service every 40,000 miles to keep your transmission going strong for years to come.

Kit includes:

• 5 quarts of Pentosin DCTF-1 fluid
• DCT transmission cartridge and suction filters
• Drain and fill plugs

Please note: We include 5 quarts of DCT fluid because without a GT1 diagnostic tool and much more involved labor, you will not be able to replace over 5 quarts of fluid. Many elect to do this service and simply flush the fluid 5,000 miles later to ensure all fluid has been flushed, but this is not mandatory.

Both the cartridge and suction filters have their own challenges in replacing. For best results, replace both.

The wheel hub assembly, often underestimated, plays a vital role in your vehicle's performance. This component connects the wheel to the chassis and incorporates metal wheel bearings responsible for wheel rotation while the car is in motion.

Over time, these assemblies can wear out and require replacement. Professional servicing can be expensive, so why not tackle this task in your own garage?
