There is some talk in the other forum of a CF hood. I think it's silly IMO to replace one of the lighter parts with CF when there are better places to reduce weight.

Back on HA I learned a bit about CF use in driveshafts. I'd like to reopen that discussion if anyone is interested. First off, does anyone know what the stock shaft weights? What are your opinions for or against on this as an option? What are the effects it would have on the tranny and LSD?

Since the HA thread is gone to the Ether I'm afraid we need to start again

I have no real data or experience with the swap, but my impression was there was pretty slim gain for the expense. It is not like this car has an exceptionally long drive shaft.. if some people cannot tell if the flywheel is lighter, chances are no one could tell the drive shaft is lighter.

The angular momentum that the drive shaft carried is very
small as the radius of the shaft is small.
So replacing a carbonfibre one will not provide much gain
in performance.
Better spend the money on lighter wheels and tires.
(radius of wheel is much bigger)

Spoon has one on their site but doesn't look like CF. Maybe Giampiero could give us a little more info ont he specs.

I defended a CF shaft before just because negative claims were unfounded, just because of the fact one wasnt made at the time so one couldnt claim either way.

Right, the OEM shaft isnt very long, and it is also very light to begine with. So there would be a small margin at best. Im spending my couple grand on new brake rotors.

I agree 100% I've had that driveshaft off enough times that I should have weighed it by now, but trust me - it's light. And as wileecoyote said, the radius is so small that it just wont make a noticable difference. Get yourself some spoon rims if you want a performance increase from less rotational weight.

One more point to add to Cdelena's Flywheel comment is that the Drive Shaft is rotating slower than the Flywheel in the low gears thus lessening the "flywheel effect" even more.
