I have one of those bluish carbon fiber shafts on my US spec 7a CQ

Mine too. Originally a Canadian 7aCQ.

snap some pics guys!

yeah. i would love to see this. But does anybody have a clue why the US got this??

So, are we talking about a direct-swap with the centre bearing and two tube sections? Reduced rotating mass is a definite advantage I'd be keen to exploit! Would also be interested to know if the unit is actually significantly lighter or if it is just an exercise in a different mass production method - I can't imagine this setup being heavier!

"Myself and others have weighed them both, and the carbon driveshaft is not lighter. It's carbon over steel."

[Keeper of The Kitten]

Right, so it's not lighter ...why on earth do a "pretty-up" of a part that virtually never gets seen?!! I can understand carbon wrapping to improve stiffness on parts that are not substantial in their own right but this doesn't make sense to me.

Maybe it`s the damping properties of carbon that Audi wanted.

I personally cut the centre bearing out of my prop and welded it together to make a one piece prop, but i did remove 10" from it so a bit shorter.

It`s made from 2mm wall seamless tube.

when you have got that sorted you can get some of these wheels to go with them.
Only 5-6 grand a set !

Easiest if we stick to the lightweight propshaft idea, if anyone has any pictures of the audi one's that would be a big bonus.
