When i get my car back from the shop (lsd), i want to order a one-piece aluminum driveshaft from enjuku. Does anyone have an aluminum driveshaft? Are there any downsides to getting one?

A downside would be is that its kind of a waste of money. Inertia is dependant on radius, and the driveshaft's radius isn't large enough to make a huge difference when getting a lightweight one. Your money is better spent on something else, IMO.

Daniel on FA and ziptied once told me of a place called Denny's driveshaft. Might want to check them out.

the only plus to an aluminum driveshaft is the weight savings over the two piece stock one.(vehicle weight overall) It has nothing to do with how much faster the engine spins(revs), or unsprung weight, just in case some of you were thinking that(on our cars that is, due to the independent suspension)

900 bucks..denny's driveshafts. the reason i brought this whole issue up is because we have the 2-piece stock driveshafts. I was thinking a one-piece may warp because(i dont know)? why wouldnt we have stock one piece shafts?

ITS BASED ON RADIUS AND STATIC WEIGHT. IF YOU LOWER THE STATIC WEIGHT BY 50% YOU ARE DECREASING ROTAIONAL FORCE. IF THE STOCK SHAFT WEIGHS 22LBS (WHICH IT DOES W/ ALL THE U-JOINTS AND BEARINGS) AND REDUCE THE STATIC WEIGHT BY HALF AND ALSO SHORTEN THE RADIUS BY 1/4" YOU WILL SIGNIFICANTLY LOWER ROTATIONAL FORCE AND DRASTICALLY LOWER DRIVETRAIN LOSSES. MATCH A LIGHTEND DRIVESHAFT WITH A LIGHTEND FLYWHEEL AND YOU WILL REDUCE DRIVETRAIN LOSSES SIGNIFICANTLY ALLOWING YOUR ENGINE TO REV FASTER BUT IT WILL TAKE MORE POWER TO KEEP YOU ENGINE AT A CERTAIN SPEED.

One Peice Shafts Are More Expensive To Manufacture And A Two Peice Shaft Is Safer.
