I was just wondering if anybody has replaced their 2 piece steel driveshaft with a 1 piece aluminum one. If you have, was there any noticeable performance gains? I was thinking about having the Driveshaft Shop build me one.

 

Due to the weight difference, I would say that you would rev faster, just like a light weight flywheel or a light weight crank pulley.

 

That was my thinking. I just wanted to know if anybody has done this and what were the issues if any.

 

I know some people have carbon fiber driveshafts, look to see if they have issuse

 

Most of us (240sx world) reported a bit of increase vibration and resonance in 4th gear (1:1) with the 1 piece AL one. But the vibration issue doesn't exist with the 1 piece STEEL one.
Both behaves like lighten flywheel, great stuff.

beside using DSS, you can give shaftmaster a try, they are a lot cheaper than DSS. Very popular among 300zx/240sx folks

PM ibkarlito about his 1-Piece Driveshaft, he is the only one I seen run one. Or maybe you could ask around on My350Z.com, since they are the one's mostly to use a lighter driveshaft/
