Carbon fiber driveshaft
Who here has experience with carbon fiber driveshafts? PST makes a driveshaft and halfshafts for our C4's. The same type are used on their 7 second mustang. Apparently they are much lighter, for less reciprocating mass, which consumes less horsepower to spin them. They also claim the carbon fiber shafts put less stress on the trans and rear, which is something we all can use, considering the C4 rear is no Ford 9" in strength!

Re: Carbon fiber driveshaft (Corvette0096)
I think they are absolutely the way to go. I have the halfshafts (not installed yet) and plan to order the drive shaft soon.
The reasons:
1) Drive line impact absorption!! This will reduce the peak stress that the rear axle, u-joints, spindles, differential, and transmission see. If you want to make your corvette's drive line live, the stupidest thing you could do is order ultra rigid, heavy duty metal halfshafts and drive shafts!
2) Safety. If you fail a U-joint or shaft, the carbon fiber shaft will not severely damage the under side of your car, or come through your floorboard and wail around in the passenger compartment. If it fails, the carbon fiber just "brooms" out and cleans the undercarriage.

Re: Carbon fiber driveshaft (POLOVETTE 94)
Dont buy them just because they are lighter, mass and radius of the shaft makes a difference in the power needed to spin them.
They are much tougher though.

Don't all act like you wouldn't spend another $1300 to go down the 1/4 mile a tenth or two quicker! You know who you are :yesnod: Of course I would never even consider a purchase like this :rolleyes: (unless that 1/10th made the car run a XX.99, rather than a XX+1.00 :D )

I do have carbon fiber driveshaft and halfshafts with cryo treated billet stuff on my webpage under the "future mods" section. :cheers:

Re: Carbon fiber driveshaft (Nathan Plemons)
On that site I see two seperate things for the corvettes. They have the half shafts, then they have one that says trans-differencial.... Whats the difference? Thought thats what halfshafts were????

Re: Carbon fiber driveshaft (Davemc1963-87conv)
My navigator runs them on his Vette & tells me the carbon fiber shafts balance out better & also absorb a certain amount of vibration. I've got carbon fiber half shafts & the drive shaft on my winter project list.
FWIW, They are avaliable with either steel or aluminum yoke ends...
