Re: steel or aluminum driveshaft?
I changed from a Strange light weight steel spool to aluminum, lightened ring gear, and aluminum driveshaft. My car is evidently dumb, because I saw zero. Well, actually, I lost first round at the last race I ran at Memphis when it cleaned the right side splines out of the spool on the starting line. About got the tree.
Still have the driveshaft. Steel spool stays in it now, and I don't spend money on lightened ring gears.
