Does anyone have any good driveshaft tips. Has anyone tried the lighter driveshafts and are they worth any gain in performance.

Anything that will lower reciprocating mass and will let your motor rev faster is a gain. As for the driveshaft our track only lets us run steel.

There are guidelines for min. wall thickness & min. diameter, for a given length / anticipated load. A good driveline builder should know the smallest/lightest that is safe for your application. If I'm not mistaken, Winston cup cars were just recently required to upgrade from 3 to 4 inch O.D. driveshafts. I have never had a problem with a 2 1/2" driveshaft.
