E46 M3 V3 Carbon Driveshaft
Swipe right for info. Scroll down to order.
Engineered for the E46's transmission tunnel.
The V2's revised carbon tube diameter is made specifically for the E46 M3.
Winded, pre-preg carbon fiber.
The carbon filaments are sourced from Toray Industries, and the tubes are finished with the signature gold filament.
It doesn't vibrate, at any speeds.
The original flex disc (guibo) is re-used, and acts as a critical vibration dampening component.
It can still flex.
The constant velocity flange has 22mm of range to absorb driveline movement.

Included hardware
Installation Kit.
As of 2025, all carbon driveshafts are packaged with brand new installation hardware.
The kit includes a new OE guibo that is used to balance with specific markings for alignment. New Genuine BMW bolts and self locking nuts are also included.
Installation Procedures
The installation of the carbon driveshaft is relatively straight forward with a few simple tricks. There are key validation protocols to ensure a successful installation.
"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!"
BUILD JOURNAL
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 Series, I bust some myths, I document the installation procedures, chat about the less than stellar BMW M manual transmission history, discuss my impressions and the V3 update.
Cheers,
