I posted one earlier about a carbon fiber driveshaft. Does anyone know about this mod if it's available, or if there is even an aluminum driveshaft? What mods are out there for tranny build ups. I know on some you can do a cryogenic hardening, but I was just curious.

 

i have yet to see carbon fiber/aluminum driveshafts available to the public. i imagine they will be very expensive if they do become available. as far as better axles all you can do is get aftermarket axles. i know zex has some and the driveshaft shop. but your looking well over $300 a set for some.
