V10 M5 & M6 Carbon Driveshaft

Swipe right for info.

It's lighter & stronger than steel.

The YFCM carbon driveshaft weights 5.6kg / 12.34 lbs for the SMG3, saving approximately 15 lbs. The carbon tube can sustain forces up 5500nm / 4000 ft lbs

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.

BUILD JOURNAL: SPECIAL SERIES
The fix is in.

The SMG3 was peak something. It got overshadowed by the MDCT and most enthusiasts gave up on it.

I doubled down.

In this Special Series, I chat about what makes the SMG3 the best of its time and atrocious per current standards.

I unbox and cover the design features of the carbon driveshaft and document the install procedures. Lastly, I recorded a few videos to support my driving impressions.

Cheers,
