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.

Save 15 lbs of drivetrain mass.
Tested for extremely high torque.
Winded from pre-preg carbon
OEM Telescopic CV 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.
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!
Each driveshaft is individually tested on YFCM's proprietary machine.
They are spun to over 8000rpm as a complete assembly.
The installation of the YFCM carbon driveshaft was relatively straight forward - it has mission-critical information and validation steps.
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.
