Driveshaft

[17GT350]

Ditto on Q1 making a quality driveshaft. I installed one on my son's 2022 GT but it didn't work out, the 10R80 transmission has unique balancing and vibration characteristics that affect the driveshaft system and we couldn't solve a high speed vibration issue. (That's why maintaining the factory clocking on the OEM two-piece shaft is critical.) A one-piece shaft is hit-or-miss on System harmonic vibration concerns with the 10R80 and re-clocking and system tuning with the crude hose clamp band-aid approach is sometimes necessary, even with a perfectly balanced drive shaft. CV joints on both ends of the one piece driveshaft would help with harmonic vibration concerns (I think that what's used on the GT500?) and QA1 was great about accepting the return.

It appears this is going on your GT350? There shouldn't be as much of a harmonic vibration concern as there is with the 10R80. Is the performance improvement from the lighter rotating mass measurable? I've been considering a QA1 carbon fiber driveshaft for my Mach 1 6-speed but I haven't seen any comparisons of how it's better than the two-piece design plus the two piece design seems to be holding up fine on the track.

Yes, this would be for my GT350. The Voodoo engine creates a lot of vibration. That is why I am asking if the C/F D/S would increase the vibration.

Good deal. Just wish I had the money right now. Can you take a IOU? jk

Going with something else? Why only 250 miles on it?

I decided to go back to stock and use the money for other suspension related improvements.
