Is this alignment OK?
Had an alignment done on the vette, and had the wheels road force balanced (OEM rims and Michelin run flat tires with 9K miles). There still is an unusual vibration felt in the steering wheel. I watched them road force the wheels/tires, so I now am wondering about the alignment job. I use the vette mainly for cruising rural roads, with only some moderately aggressive driving. I want a SMOOTH ride with minimum ire wear. So, please give me your opinions on these alignment settings:
Front Left:
Camber -0.1 degrees
Caster 6.8 degrees
Toe 0.07 degrees
SAI 8.5 degrees
Included Angle 8.4 degrees
Front Right:
Camber -0.1 degrees
Caster 6.9 degrees
Toe 0.02 degrees
SAI 8.6 degrees
Included Angle 8.6 degrees
Front:
Cross Camber -0.1 degrees
Cross Caster -0.1 degrees
Cross SAI -0.1 degrees
Total Toe 0.09 degrees
Rear Left:
Camber -0.2 degrees
Toe 0.00 degrees
Rear Right:
Camber -0.2 degrees
Toe 0.02 degrees
Rear:
Cross Camber 0.0degrees
Total Toe 0.02 degrees
Thrust Angle -0.01 degrees
Thanks for your time and help.

It's alright to drive on. It's very mild though. I would also have been **** about equal toe from side to side but it's not that big of a deal.
Mine for the street would have been more like:
Front:
Camber -1.0
Toe 0
Caster as much as possible
Equal on both sides
Rear
Camber -.5
Toe -.01
Equal on both sides

Alignment should not be causing a vibration problem. If you are sure the tires are balanced, check shocks. My guess is the wheels are either out of balance or bouncing due to weak suspension parts.

A final thanks to all who answered my questions. Things are as good as they're gonna get, which is not too bad. So I'll leave things, from this point on, well enough alone.
Thanks again.

Good info. I have always run 1.5 to 2 deg negative camber. Of course, my cars are always weekend cars (more once a month cars) and tire wear is not a criteria for me....
