Factory Fit FX400 8-Puck Twin Disc Clutch Kit

The Clutch Masters Factory Fit FX400 Series Twin Discs kit for the 2021+ BMW G80 M3 and G82 M4 with the amazing S58 engine and a 6-Speed manual transmission was developed to bridge the gap between replacing the comfortable driving twin disc that came in these cars from the factory and one of our more race orientated 725, 850 or 1000 Series twin disc kits. As OE auto manufactures continue to push for more and more power, they are typically equipping those cars lucky enough to be outfitted with a manual transmission with a twin disc clutch. But what happens when the factory clutch starts to wear out or slip because you've modified and tuned the car? Lots of owners of these higher end powerful cars still want to maintain a car that is easy to drive on the street, yet still be able to reliably take the abuse they inevitably want to throw at it. Most aren't looking to go full race car and install a twin disc designed for such use, there has to be a compromise.

Our answer to these dilemmas is our Factory Fit FX Series Twin Disc Clutch Kits. Using components similar to what came in the car from the factory, the Clutch Masters engineering team does everything they can to expand and improve upon the OE twin disc in many ways. Using higher end friction materials, lighter materials and their expertise in developing performance clutch kits for over 45 years, they dial in a twin disc kit that bridges the gap between full race car and luxury daily driver making serious horsepower. In the case of the BMW G8x twin disc, they have done away with the factory self-adjusting cover, a little over 10lbs of weight reduction in the entire assembly, and have gone from an 8.5" disc to a 9.5" disc for significantly more disc surface area. 

The Clutch Masters FX Series Twin Disc kits utilize their proven friction materials found in the FX Series Single Disc Clutch kits and are available in several different configurations to suit you and your cars needs.

The Factory Fit FX400 Series Twin disc will come as a complete replacement kit utilizing a lightweight aluminum Type 3 hard anodized flywheel, steel floater, factory style stamped steel cover, two DLX clutch discs utilizing their ceramic friction material, throw out bearing, and clutch fork.

This clutch is designed for the street enthusiast who is making considerable amounts of power over the stock setup. The FX400/HDCL (8-puck) ceramic full face disc design creates a quick and rapid engagement and maintains minimal chatter due to the marcel cushion between the disc linings.

**Ceramic based clutch disc are not intended to increase the life expectancy of a clutch but rather to increase the holding capacity and improve the durability of the clutch. Using a ceramic based material for easy street driving may reduce the life of the clutch kit due to harsh engagement and higher tendency to slip the clutch kit. Ceramic disc are never recommended for stock or near stock vehicle applications.**

** It is highly recommended to eliminate the factory clutch delay valve. Not only will removing this piece improve the cars ability to shift quicker more efficiently, it will also help improve the lifespan of your new clutch **

Good for dc power supplies
Size: 6ft, Color: Yellow, Size: 6ft, Color: Yellow
The AC outlets are very snug. I’m using this primarily for battery tenders and battery chargers; the outlets are spaced far enough apart to fit the dc power supplies and they stay in place even when mounted horizontally.

Cheap, looks good and works good
Size: 13"-32", Style: Dual Arms
Mostly painless install, packaging was subpar but everything works well. Holds a 27" monitor and a 24" monitor very well. Adjustable angles and hinges allowing for customization for your needs. Seems to be very sturdy and hasn't dropped since making sure everything is tight. Overall, worth it compared to more expensive options.

Sturdy, Extremely Adjustable, and Saves Huge Desk Space!
Size: 17"-49", Style: Single Arm
This WALI monitor mount is incredibly solid and handles the weight of my monitor easily without any sagging or shaking. The gas spring arm moves fluidly, making it super easy to adjust the height, angle, and tilt whenever I need to. Installation was straightforward with clear instructions, and it has freed up so much valuable desk space. Excellent build quality for a great price!

Solid Mount for a Large Monitor
Size: 17"-49", Style: Single Arm
Picked this up to mount a single 37" monitor to my adjustable desk and it’s been working great. The arm feels sturdy and holds the weight of the monitor without sagging or drifting over time. Installation was pretty straightforward and it gave me a lot more desk space compared to using the factory stand. It also moves smoothly when adjusting the monitor position or changing desk height. If you’re running a larger display on a standing desk setup, this is a solid option that feels much more substantial than some of the cheaper monitor arms out there.
