My issue didn’t change much with ride height. I know at one point I took the car on an open road late at night and while driving I turned the ignition off and the car turned extremely stiff but the vibration disappeared. I did try this at very low speeds to make sure I had access to steering.

Understood. Thank you. What about dampening? Any change when you go from comfort to sport?
Gonna tinker one more time with the PASM control unit but my gut tells me that i have to go back on the lift and follow the road rash on the rocker panel that coincides with my gut's telling me that my harmonic vibration definitely comes from more right of center. Going to have to look at the drive shaft, wheel bearing AND bushing in the lower cross member - i just don't know why any of those would change frequency to be less frequent on either side of a certain speed range of around 56ish mph AND imply that people were launching Panameras off of curbs in Houston solely and you have one of them and i have the other?
Update: I stand corrected; the sweet spot for the start of the vibration for me as well is 53 miles an hour. I do feel it increase and then decrease again at 80 something miles an hour, but I don't think I was paying attention to it the other day, when I looked down & the speedo and I was doing 57. On the drive home last night the initial increased frequency is noticeable at the speed of 55ish for sure.
Going to have to go back on the lift, and start looking for play somewhere because the frequency of the vibration does not change with speed, just the intensity of it. Correct?
Pushing PASM switches only makes it more or less noticeable once we get up and over 55.
I know these questions are redundant and for that I apologize but I have to make sure that I am going down the list.
Don't own a Panamera yet, but thinking of pulling the trigger on a CPO 2018 4S with 40K miles on it.
It has the 21" Sport Design Wheels.
When I go to test drive it I'll be watching for the vibration.
One suggestion, I know tires/wheels have been ruled out, but I'm curious if there's some commonality to the brand/type of tire you guys have.

I have run both Pirelli PZeros & Pirelli Sottozeros on 21" rims, and also tried Michelin Sport A/S tires on 20" rims.
Good luck in your search--just be sure to test drive, test drive and test drive again!
Been reading your thread. There might be a design defect. Once the various mechanical parts wear to the point where they vibrate more than a new component, they may excite a natural frequency in some other component(s). When they created the design they test with “tight” clearances so they would not know about this.
You have enough folks having this problem so it may be worthwhile to contact corporate, with detailed documentation and ask for help. I’m sure their engineers can install vibration sensors to pinpoint the problem.
I have a 2014 970.2 and was considering an upgrade to a new GTS but this thread has me concerned.
@BGB Motorsports Any new thoughts or discoveries? My 9Y0 Cayenne S vibrates at the discrete speeds mentioned in this thread in Sport+ (lowered, stiff damping) and Normal (not lowered, soft damping) settings.
What do you think about an exhaust hanger or flex pipe? An Audi owner with EA839/ZF8HP powertrain reported vibration similar to this one and it was solved by the dealer replacing the flex pipe components and exhaust hanger.
Anyone have this issue with the 'rare' base 2WD model (3.0 V6 with single turbo)? That's what ours is, and at 10K miles now (2019 model), still very smooth at all speeds. I don't think it is the engine in these vibration cases.

The way this is looking, I don't think 2WD models will affected. The vibration/defect seems to be in the front section of the 4 wheel drive train.
