in collaboration with YFCM COMPOSITES
2023 Winter Group Buy

After a year of research, development and road testing, the E46 M3 and V10 M5 & M6 applications are now available in all their transmission types, joining the established, original E9x M3 V2 product.

I'm excited to finally create a classic EuroConnex Group Buy that gathers all the social buying community together.

It's lighter than steel.

The YFCM carbon driveshaft saves between 10 to 15 lbs depending on the application.

It's stronger than steel.

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. 

It doesn't vibrate, at any speeds.

The 1 piece design retains the use of the flex disc on the transmission output shaft, a critical component to remaining street friendly.

It's made from the highest quality carbon.

The YFCM carbon tube is is winded from pre-preg carbon fiber sourced in Japan from Toray Industries with the signature gold filament.

It can still flex.

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

Machined from 7075 forged aluminum, the flange is a self-locking, sealed design.

It locks over the carbon tube, eliminating all probabilities for the tube to spin free of the flange, no matter the torque.

Tested & Warrantied

Each driveshaft is individually tested on YFCM's proprietary machine. They are spun to over 8000rpm as a complete assembly.

Each unit has a 1 year replacement warranty.

"Finally got round to fitting the carbon propshaft on my e92. One word wow! Revs up quicker and zero vibrations!"

"I said to myself wow, this is how I always thought it should feel: no vibrations, just solid feeling & amazingly smooth delivery.

It is complimented so well with the CAE street shifter, what a combination!"

"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!"

Installation Procedures

The installation of the YFCM carbon driveshaft was relatively straight forward - it has mission-critical information and validation steps.
