dumb question
 

with an aluminum driveshaft will you see any gains in anything, rwhp, 1/4 time.........anything?

Your reducing rotating mass + making the car lighter. Minimal gains in the 1/4, not worth the money unless youre into serious racing.

It should improve your 1/4, but very minimal. However it will let your car rev up alot faster. :)

alrite i was just wondering cause when i was doin the h pipe i noticed how rusty mine is.........only thing under there thats rusty and it was bothering me

Spray it with some VHT paint.It won't last but it'll cover up the rust.

Ya like everyone said, its just lighter. They have a carbon fiber one available for us if you really want to dish out some money for it. Thats super light and super strong.

lol

Same idea is behind the Aluminum flywheel...

Lighter, less rotating mass, quicker revving.
