Vibration from 75 to 85 mph - If not wheels and tires, then what?
My TT has over the last 10k miles with both summer S03's and winter Nokian had an annoying vibration between 75 and 85mph. The rear privacy shelf rattles like crazy, I feel in the steering wheel and I can feel it in the left foot rest.
Above and below these speeds everything is fine.
Wheels and tires have been balanced. I think I will try that again, except this time on a Hunter Load Balancing system.
I am thinking this could be bad motor mounts.
With aftermarket wheels/tires/suspension I seriously doubt my dealer replacing anything under warranty.
Your thoughts, experiences, and suggestions are appreciated.

If the vibration occurs in both the winter and summer setups, my suggestion is have your car shop check all bushings and suspension connections in the front.
If the Vibe only occurs on your summer setup, the first thing that comes to mind is a high speed wheel balance - most shops dont do this unless you specifically ask for it. Again I suggest that you focus on the front wheels.
If you dont want to take a trip out to your tire shop, do a front to rear tire rotation, if the vibe can be felt in the cabin (not the steering wheel) you prolly do need a high speed balance. This worked on my beater (front wheel drive)
Good luck-
PS you could drive 90 or 70. that is what I did on the beater until I fixed the issue
