I was going to guess "tail happy" with that camber difference and 0 toe out back.

Yeah, i have not had any time to drive it that way but, I think I may have them go to 0.0 toe in front.

btw, do it yourself. Unscrew each rear adjuster 2 "flats". This will yield just under 1/8" toe in.

A "flat" is the amount of one wrench turn, or 1/6 turn.

Where do you find the rear adjuster?

Your help is appreciated.
How much is -.05 as displayed on my alignment sheet
in inches. Anyone have a conversion table for that?

You've got it backwards. A little toe-in helps with rear stability. Toe-out out back would make it fairly crazy.

Here's what I have:
Front: -1.1deg camber, -0.06deg total toe (out)
Caster: 7.5deg RF, 7.9deg LF
Rear: -0.9deg camber, 0.08deg total toe (in)

7500 miles, fourteen 20 minute sessions at Thunderhill, four autocrosses (twenty 45 second runs?), and the tires look to be wearing evenly... stock Z51 tires.

I have -.05 to per side in front for a total of -.10

Is that way to much?

The shop I went to had a conversion chart next to their fancy Hunter machine. I can't seem to find one online, but I recall a thread recently had the math in it.

Edit: I just wanted to note again that I'm no alignment whiz and this alignment of mine is just the starting point from the shops asking me what I intended to do with the car. This alignment has worked out okay for me for the combination of driving I described above.
