Re: steel or aluminum driveshaft?
I've often wondered if the reason that lightened axles,driveshafts,etc. don't show an increase in performance is because of the short distance we run.In other words if you made the same weight saving modifications to a Bonneville salt flats car, it has a longer period of time to effect the car.Of course they don't measure E.T.and I could be wrong also.
