It's cold. These tires are like rocks right now. So I would wait until warm spring temps to see if it persists. My 2 cents. Wow! I missed this is your first post too! WELCOME.

Make sure to announce yourself in the New England section and sign up your Z in the ZL1 section.

I don't experience this.. i've got about close to 3,000 miles on mine now. My rig is smooth cruising up to 90s in 6th gear .. even if i push the accelerator down i don't have any vibration .. check your lug nuts. there are a few cases where they do come lose .. sometimes you have to re-torq them.

Try downshifting to fifth using the paddle shifters and see if anything changes at 70.

Could be, but usually tire problems show up at lower speeds.
