aluminum driveshaft
 

i know it reduces rotational weight but is it really worth the price, can you feel a difference......now that i think of it i have not seen anyone on this forum with this mod....any info would be nice thanx trnin

It lets you rev faster i think

Getting a lighter driveshaft creates less rotating mass, i've seena guy put a driveshaft on his car thats 18 lbs lighter than stock, and shave .2 off his q-mile

how hard is the install for this

As someone stated before, your engine will rev a bit faster.. :)

yep, the motor will accel faster because its spinning less weight and faster revs means quicker car.

only when the car is moving. remeber that every 10pounds of rotating mass taken off is about a tenth in the 1/4.
