Im suprise at the alignment specs (althought Buns, thanks so much for posting this!!). Typically on a high performance/race set up, one wants Toe OUT in the front and Toe IN in the rear. This is what we do on 911's and they are known to handle pretty well.
Toe out in the front will provide stability and make for quicker turn in and having toe out in the front and toe in the in the rear will make the car run straighter down the road.
On big tracks like Daytona, where speed and banking can heat the heck out of tires, I run 0 toe in the rear...
To me it looks like Speed Direct and Herb Adams are on the sharpest point.....

I am aboat to finish my Red car with a full Shark Bite suspension and I have to align the Black Car with a full Van Steel suspension and i'm now excited to put the cars up on the rack and try them out with the SD or Herb set up, but then again, I like very sporty/race alignment that is closer to race than street

You guys are making me appreciate my location, Cleveland, Ohio. There are several good shops to take your vintage Corvette to. I go to Corvette Conspiracy. They do excellent alignments. They know these old Corvettes inside and out.

From John Hinckley:
Midyear alignment specs for normal driving on radial tires have been posted here dozens of times:
Front camber: 0*
Front Caster: 2.5* positive (if you can achieve it)
Front Toe-In: Zero to 1/16" TOTAL Toe-In.
Rear Camber: 1/2* Negative
Rear Toe-In: 1/32" per side

"Sport settings" are up to neg. 1 degree camber at all four corners, and I also recommend hard front anti-roll bar link bushings, and set caster as high as possible. In all cases cross readings should be as close to zero as possible.
Alignment settings are a chassis tuning parameter and are not absolute. OE recommended settings are generally conservative to promote understeer and even tire wear. The primary difference for bias and radial ply tires is toe. Since radials have longer contact patches and more self aligning torque than bias ply, they work best with a small amount to toe.
