E60 M5 Carbon Driveshaft
by YFCM Composites Technologies
BUILD JOURNAL: SPECIAL SERIES
Demystification.
It isn't weaker than steel.
It isn't like a flywheel.
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 my V10 M5.
In this Special Series, I take you through technical review, unboxing, installation, driving impressions & more.
Cheers,

Save 15 lbs of drivetrain mass.
The YFCM carbon driveshaft weights 5.6kg / 12.34 lbs for the SMG3.
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.
Patented Self Locking Flange
No ungluing.
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.
Spec your driveshaft
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!
Tested & Warrantied
1 year replacement warranty
Each driveshaft is individually tested on YFCM's proprietary machine.
They are spun to over 8000rpm as a complete assembly.
Installation Notes
The installation of the YFCM carbon driveshaft was relatively straight forward - it has mission-critical information and validation steps.

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.
