Yeah when I called PST last week they said they would only do CF and I was surprised when I called Drivetrain Industries and they said the same thing. At that point I knew CF was the best route.

Yes you will notice a difference.


Plus as far as the centrifugal force is concerned with your "moment of inertia" (fictitious force) for that part of Newtonian mechanics. Is and will change the effect of deceleration, also better maintaining the holding force of the clutch pack in the transmission, as well as increasing all mechanical values of acceleration more efficient. This is actually a very non-debatable topic lol.


If we were to toss in fluid and were looking to change the density, mass, separate, strip and or refine material. Then yes, the small diameter would be less affective at the same rotational speed, less opposing force, less efficient, not as consistent and would need a much longer (barrel) to achieve a desired property for a majority of (material). However thats not the reaction were going for, but is also apart of Newtonian mechanics. So I get'cha

Yes sir, I sure can. Keep reading and call PST for the price.


I'm the guy that measured it out and what not, its PERFECT!


I will try put a thread together tomorrow if I have a bit more time. So look out for it.

- Check the Tech area (drivetrain), I started a thread for ya's

I'm a bit more worried to get one now that I'm running a little less than 400 to the crank and rev to 8000 rpm.


No worries there, a Alpha12 GTR wouldn't even stress this.

Do your research. No aluminum for these cars. I have the PST driveshaft with 4.08 gears and it does make a difference. Who ever says it doesn't has no idea what they are talking about..

How is/was the drivability with the driveshaft? Extra fun???

Of all my reading through the 370z and G37 forced induction builds, I do not know if I have ever heard of someone destroying their driveshaft. doesn't mean it hasn't happened, but it doesn't seem to be a weak point. It is certainly not an issue at the 550-600 WHP mark. You should be fine.
