M3 V8 V2 Carbon Driveshaft
Swipe right for info.
It's lighter.
The YFCM carbon driveshaft weights 11 lbs for the 6spd and 13 lbs for the MDCT, saving 12 lbs of drivetrain mass. They can sustain torsional forces up to 5500nm / 4000 ft lbs.
It's stronger.
The YFCM carbon tube is winded from pre-preg carbon fiber and can sustain up to 4000 ft lbs / 5500nm of torque.
It can still flex.
The rear CV flange is oiled, telescopic and heat treated, helping to absorb drivetrain shock in hard driving conditions.
It's vibration free.
The 1 piece design retains the use of the flex disc on the transmission output shaft, a critical component to remaining street friendly.

Installation Procedures
The installation of the YFCM carbon driveshaft is relatively straight forward with a few simple tricks. There are key validation protocols to ensure a successful installation.
Patented Flange Design
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.
Recommended Hardware
I have curated installation kits with the recommended hardware for properly fitting the E9x M3 carbon driveshaft.
"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!"
BUILD JOURNAL: SPECIAL SERIES
Everything is tighter - thus faster and smoother.
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.
