There will be eternally be something special about pushing down on a clutch, swapping a cog and releasing your left foot and pushing into the power pedal.
It's the feeling.
Can retrofitting technology introduced on the F8x M3 enhance the 420G?
In this Special Series, I bust some myths, I document the procedures, chat about the less than stellar BMW M manual transmission history and Ryan & I give you our driving impressions.
Click, click, BOOM!

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.
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 500+ M3 V8 owners for years.
