E46 M3 V2 Carbon Driveshaft
Tap right for info.
It's lighter & stronger than steel.
The YFCM SMG carbon driveshaft weights 11.9 lbs versus the OEM at 18.7 lbs. The MT is lightened further with a shorter flange. The carbon tube can sustain torsional forces up to 5500nm / 4000 ft lbs.
It's made from high 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 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 can still flex.
The CV differential flange is oiled, telescopic and heat treated, helping to absorb drivetrain shock in hard driving conditions.
Spec your driveshaft
BUILD JOURNAL: SPECIAL SERIES
Got my 420G feeling like a Springfield.
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!
Cheers,

"The CF driveshaft makes the 420G much more nimble esp when paired with the flywheel. It makes the downshifts crispier. The whole car feels lighter and it really enhances the special car-driver connection that the E46 M3 is famous for."
"The difference was felt not in way of weight savings, it was felt in terms of direct drive/positive traction. The shaft picked up all of the slop from the OE drive shaft with its center support bearing"
"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!"
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.
Installation Procedures
The installation of the YFCM carbon driveshaft was relatively straight forward - it has mission-critical information and validation steps.
Tested & warrantied
1 year replacement warranty
Each driveshaft is individually tested on YFCM's proprietary machine. They are spun to over 8000rpm as a complete assembly.
