there is some very noticable vibration. the rear-view vibrates bad enough that you can't even see behind you with it. Up to 140 it's fine.
just an alignment issue?

Alignment or balance. I'd check the balance first.

I notice alot of vibration on the videotape of my rides over 140, most recently at VIR. I think this is normal turbulence. It may not be as bad if the windows were up, but they are always down at the track.
I think alignment issues are likely to be felt at lower speeds. One wheel out of balance gave me a vibration at 80 mph.
At 140, I am concentrating on everything. In 4th gear, this is just before the shift to 5th. My car feels solid, but there is alot more information to process at that speed. I have not lowered my car. I have a rake of 3/4" from front to back. With less of a rake, the front end seemed to get light at that speed.

Most likely tire balance, alignment does not affect or cause vibrations. Are you certain it's really an abnormal vibration eminating from the car/tires etc. and not buffeting at high speeds?
