E46 M3 V2 Carbon 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,

It's lighter 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.
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'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 and telescopic, helping to absorb drivetrain shock in hard driving conditions.
PATENTED SELF LOCKING FLANGE
It will never unglue.
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.
Machined from 7075 forged aluminum. The flange is weight optimized and anodized for corrosion resistance.
Spec your driveshaft
"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!"
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.
