Carbon fiber driveshaft?
Just curious if anyone is running a CF driveshaft, or knows of experience with one. I'd like to take a touch more weight off the car, and the failure mode of CF shafts seems safer than metal shafts.
I have been running carbon fiber half shafts (solely to save weight) for over 15 or so years with no problems. I got them from Vansteel, don't know if they're available now. I considered a fiber driveshaft also, but the smallest diameter available was 3 1/4" which was too large to fit in the tunnel. I opted for an aluminum driveshaft instead, 3" diameter, barely fits but OK.
To be strong enough to take the torque loads, the driveshaft (and half-shafts) need to be a fairly large diameter, considering that CF shafts are just hollow tubes.
Not worth it! You still have the metal ends and u-joints which are the weight. I have a chromoly with billet steel caps and 12 point ARP bolts. You have to remember that mine is only 29.5 inches long. So I only have a smaller diameter maybe 2.5 inch chromoly VS CF. Where to save weight is really light weight wheels and I got rid of the parking brake assembly that I never used anyway. I have a front roll control to lock the front tires if I had to, but it would be drawing some current

What are those brackets welded to the diff cross-m?

Yes.......my half shafts are 3.5" in diameter. Most of the CF driveshafts are also 3.5" diameter. Too big to fit in the C3 tunnel.
