Maybe in Supras 
I’m willing to bet that the vibration issues have more to do with improper balancing of the after market driveshaft than the removal of the center joint.
There are driveshafts available for the Z that have dampeners built on the end to compensate for any lack of balancing. And they still cost less than replacing the factory driveshaft with another factory driveshaft since, on a Z, the center u-joint can’t be rebuilt.
Not to mention it’s been debated that a 1 piece driveshaft reduces some drivetrain loss. But That doesn’t matter to me. I just need to replace my 15 year old, starting-to-“slop”-under-the-power driveshaft. And I haven’t heard any negative impressions of a 1 piece driveshaft on a Z since they first came out several years ago.

ughh, i had terrible vibrations on my Z. For the longest time, me and my father were baffled, then we finally figured it out. Then I remembered that you could buy the 1-piece aluminums online.
Instead, we found a place that makes driveshafts, and went that route. They did the job for ~250-300 bucks. It made a WORLD of difference, the car felt much more crisp and snappy afterwards.
