E9x M3 V2 Carbon Driveshaft
by YFCM Composites Technologies

The major benefit to the YFCM carbon driveshaft is improved chassis & drivetrain response. It's been one of the best upgrades to my M3 V8, E46 M3 - and soon, my E60 M5.

In short: it's a lot lighter and more rigid than OEM 2 piece steel, it remains vibration free, won't unglue, everything is tested, every time - and it's backed by a 1 year warranty. 

I've put together an extensive knowledge base for you to learn more about carbon driveshafts.

Cheers,

Save 12 lbs of drivetrain mass.

The YFCM carbon driveshaft weights 11 lbs for the 6spd and 13 lbs for the MDCT.

Tested for extremely high torque.

The carbon tube was engineered and tested by YFCM to sustains forces on proprietary torsional stress machine to over 5500nm / 4000 ft lbs of twisting force. 

NVH free

The 1 piece design retains the use of the flex disc on the transmission output shaft, a critical component to remaining street friendly.

Winded from pre-preg carbon

The YFCM carbon tube is is winded from pre-preg carbon fiber sourced in Japan from Toray Industries with the signature gold filament.

OEM Telescopic CV Flange

YFCM uses an OEM grade CV flange to connect with the differential. It is oiled and telescopic, helping to absorb drivetrain shock in hard driving conditions.
No ungluing
Patented Self Locking Flange.

The flange is a self-locking, sealed design: it locks over the carbon tube. It eliminates all probabilities for the tube to spin free of the flange, no matter the torque.

Machined from 7075 forged aluminum. The flange is weight optimized and anodized for corrosion resistance.

Each driveshaft is individually tested on YFCM's proprietary machine. They are spun to over 8000rpm as a complete assembly.

In collaboration with Steven Lee @ YFCM Composites Technologies, we debunk the common misconceptions about carbon driveshafts.

Most of these myths are driven by design shortcomings of other brands. I compare the YFCM V2 to the MFactory V3 that I previously tested.

Installation Notes

The installation of the YFCM carbon driveshaft was relatively straight forward - it has mission-critical information and validation steps.

Recommended Hardware

1x Flexdisc "guibo" (SKU: 26112282573)
1x Balanced CV flange / Diff bolt (SKU: 26112284154)Actual SKU may vary depending on your diff & driveshaft balancing specs. My diff had a blue line and it indicated the Black balanced bolt. 
For more information, refer to RealOEM diagram here
5x Standard CV flange / Diff bolt (SKU: 26117526322)
3x Self Locking Nut for Guibo / Transmission flange (SKU: 26127536563)
6x Hex Bolt for Guibo / Transmission flange (SKU: 26117527475)

Mashing on the throttle is instantly translated to power – it’s like driving an electric car.

I was able to take it to 110 MPH (in Mexico) with 0 vibrations or humming. I’m ecstatic!

Made in Taiwan

M. Lee is the man behind YFCM Composites Technologies and the patent holder to the signature technological innovations.

He also operates an industrial automation company in Taiwan. He used his knowledge to develop proprietary stress testing equipment specific to automotive carbon tube applications. 

YFCM has been the manufacturer all along for the MFactory V2 that was acclaimed by M3 V8 owners for years.

I documented at length how I uncovered MFactory's V3 fraud, ultmately discovered YFCM, and brought back the lauded V2 product.
