It's lighter & stronger than steel.
It's vibration free.
It's made from highest quality carbon.
It can still flex.
In this Special Series, I cover the bizarre backstory to uncovering the manufacturer of the authentic V2 product, and I compare it with the counterfeit product from China I personally tested.
I follow it up with documenting the installation procedures and cover my driving impressions along with other members.

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.
The installation of the YFCM carbon driveshaft was relatively straight forward - it has mission-critical information and validation steps.
"Finally got round to fitting the carbon propshaft on my e92. One word wow! Revs up quicker and zero vibrations!"
"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.
Been there, done that.
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.
