Vibration problem Help!
I have a 2007 z06. Tires are not chopped and the wheels are all balanced. At 70 mph the car is very smooth. As soon as i hit 73-80mph it sounds like i am going over rumble strips every 5 seconds. As soon as i slow down it goes away. Help would be very much appreciated thanks
it vibrates through the steering wheel as well as the seats

Sounds like wheel bearings. Somewhat common issue.
Here's just one thread for example:

Mine did that and balance fixed it. I would either re-balance or have tires checked with roadforce balancer. You may have a tire that balances fine by weight but maybe out of round or has excessive roadforce.

I noticed it first by driving on the interstate, noise would go away in one direction and disappear when turning the other directions. steering wheel felt like a vibrating cellphone in my palm. Started faintly at 40mph and became unbearable t 75mph and up. Good luck.

I personally have operated the Hunter RoadForce balancer at our local Junior College. Used it on my 2006 Corvette, 2008 Bullitt Mustang, F150 and son's Miata. I do not recall any calibration required. I would guess the operator did not have the wheel and tire assembly clamped straight or tight enough. It is possible that he used the wrong cone to center the wheel. Also it is possible he attached the weights in the wrong place. These machines are not difficult to operate, but you do have to pay attention.

This is a good reminder that just because the tech says the wheels are balanced does not mean that there can not be a problem.
I went around and around, my self, with this problem.
Mine turned out to be after market rims not seating correctly on the hub. Turned out that a strip of tape around the hub fixed the problem, rough vibration above 70 mph.
Since I have returned to factory rims.
