Think about safety first!!

Folks, the decision to purchase the ACPT carbon fiber driveshaft versus other aluminum driveshafts should not just be based on cost and weight considerations. Of utmost importance is safety. I recently had a discussion with another member in the linked thread below, and found that using a 1pc aluminum shaft may not be the safest approach to saving weight: https://g35driver.com/forums/engine-...-delete-3.html

A very good point brought up by Dr. Ephil was that during an accident or driveshaft failure, the driveshaft could potentially enter the cabin or exert very large forces on the car causing further damage. A carbon fiber shaft would simply shred, as highlighted on the ACPT website.

We all understand that cost is very important, but never at the expense of safety. There's a reason the 350Z and GTR, both which use a single driveshaft, use carbon fiber as the material.

great point. is there a way to use the idler with the aluminum 1 pc.

I got the CF due to be the extreme lightest, esp when combined with LW clutch and flywheel.

I wonder if there are any disclosures on the Z1 site on their single DS?

Not just trying to protect us, trying to protect one of our best vendors as well.

Finally got all my blower bits machined and back in one place

im boosted (Vortech Ttrim) but Ill do CF vs OEM drive shaft just for shitz and giggles. its a quick swap so shouldnt cost me much, maybe the shop wants to do the comparison and I can get them to do it for free or cheap.

give me about a week or so....

That's too baller for me. I don't see the issue of it being aluminum that big of a deal. I see it the same as installing a BBK, which can kill you just as easily should it fail. Just make sure it's a quality part (which it seems to be in this case), and make sure it's installed correctly.

The probability of all 4 brakes (BBK or regular) failing is much lower, and if they do all fail, you still have the ebrake. However, if you're involved in an accident where there is force exerted on the front or rear portions of the drive train (perhaps from your BBK failing), that aluminum shaft will not absorb any energy and will instead deflect. So you'll end up not only with failed brakes, but a much worse situation with the driveshaft becoming a projectile.
