put it this way…

my car from the factory had a 3.5" aluminum driveshaft. It broke.

I now have a 3" chromoly PST driveshaft with a forged yoke. Guess what? my car is the same with it.

your theory is butt fucked. Your talking a very minimal weight difference. If you wanna talk about rotating mass, looking at wheels/ tires or even flywheel’s. Not the driveshafts.
