Charlie's drive shaft is not straight carbon fiber.  The core is an

aluminum

tube.  It is wrapped with carbon fiber at a bias to make the tube much
stiffer in torsion.  This was done to raise the resonant frequency of

the

drive line to above any problem frequency.   One more time:   Those
aren't rivets!

Tracy, thx for the explanation. What are they (screws), and what purpose

do they

serve? Interesting combination.

I think the screws are to couple the drive shaft to the damper assembly on
the flywheel.
