Aluminum Driveshaft?
Do aluminum driveshafts help that much? What I was thinking is they either give you more of an RPM range or they transfer more HP and torque over to rear wheels, but I'm not sure.

They reduce the total rotating mass that has to be accelerated from 0 RPM to whatever their RPM is at the finish line. It's not a real big thing, but every little bit helps.

When my dad had his 92, he swapped to aluminum. It made a very small difference in acceleration. Like RB83L69 said, it's just less weight for the engine to turn.

They do make a pretty decent change...Nothing like nitous though.. It's less weight, so it's quicker to get up to speed, because it's easier for your engine to turn, also it is alot less strain on your tranny and engine cause it's lighter and eaiser to move..think aobut yourself..you wana turn somthing heavy for hours on a day, or would your rather it be light? Had a aluminum on on the 2002 ss...it twisted..had to get the steal one back on...Carbon fiber is just too expensive..

i just got a practically brand new one of ebay for 146 shipped, not abd at all, deosnt even look used. i beleive they are 10 lbs lighter then the steel AND they are a lot safer due to not having a critical speed like a steel shaft does. this means when ur doin 140 the saft isnt likely to vibrate so bad it comes through the floor pan on ya.

i look at alot of the changes made to production cars and go..... WTF?! why the heck would they change that!?
theres a million possible reasons besides whats best for the car... could be cutting costs, or they subcontracted a diff manafactuer, who knows..?
im just getting the impression that there is more then one.

it may be of thicker material for strength
as actual diameter affects overall strength
