Update:
After some more testing this afternoon....
I still had a very very slight vibration on low (occasionally), and a bit higher intensity on the med setting. Basically, the same as yesterday, even though I changed my front links from setting 4.4 to 5.
So, found a long steady uphill grade and was able to hold at 43 while cycling the suspension from low to med and back twice on the same hill. Did this many times and in every case the vibration increased when dialing the height up and decreased when dialing it down. This is the only way to test - constant speed and grade while cycling the suspension pumps! When I returned home, I measured and the front height was still 28” on low (same as yesterday) even though I increased the front links by .6mm - so that’s consistent with the vibration from yesterday and today, on the low setting.
What’s weird is the rear was a little higher today (1/4"), even though I didn’t change the rear link settings at all. This leads me to think there is height variability inherent in the air suspension design. This might also explain why some feel a vibration some of the time and not at other times (ride height changes on it's own by a 1/4" +/-) from drive to drive.

Update, on "Twosday" - 2/2/22
Decided to take the car out in 30 degree weather, in the name of science - as the roads were clear and mostly dry this afternoon.
To start off, I lowered the car 3/4" total (Setting 6 on the RSX-2 Plaid links) in the front, and 5/8" in the rear for today's more extensive testing.
Zeroish Vibration at this setting (low), for the hour I drove around!!!
Summer tires were rock
hard, I imagine, so that's why I say, "Zero-ish".
Raising to med height brought an infrequent ever so slight/noticeable vibration at the 43mph test point (less than what was felt yesterday at the med setting when the car was dropped 1/2". In all cases, this minuscule vibration "dialed out" when I set the suspension back to low. And, keep in mind, even with only a 1/2" drop (tested yesterday and the day before) the vibration intensity and frequency (when felt) was less than 20% of what it was before these mods!
A point to note: I noticed, when at testing speed, that I hit a little dip in the road. My suspension was on "Comfort," mean more rebound than on Sport or Advanced with sport toggles on. When coming out of the drip, at maximum rebound height, I felt some vibration for a split second. Of course, this is the result of a momentary high point with increased CV angle! So, for grins and giggles, I reduce the "rebound" by setting the suspension to "Sport" and retested. Momentary vibration at peak was gone.
Tried Cheetah mode; no issues (other than my front flaps touching the ground)... To fix this, I just went into Cheetah mode at the med setting.
Next Steps: Continue driving at this setting for another day or so. If no vibration, dial the links back up to stock and retest. If vibration is there in force, we would definitely be zeroing in on the root cause.
