Just for clarity, please confirm your car is a base coupe/vert, not GS?
Those pages are really difficult to read. The only one worth looking at is #7. You could probably delete the others if you want to.
Interesting, quite a few items were out of range. Good thing you had it done. Thanks for sharing.

vette
that was on a brand new car 22 miles..... my 06 had the same problem and i didnt pay attention.i had to buy two new tires.. the alignment shop gave me a quick class. i think he even adds weight to your car to simulate body weight..

The alignment on the Vette doesn't seem to hold that good. I just had my 3rd one done at 24k miles. I noticed the last one was bad because the inside of the LF tire was wearing quicker than the rest of the tire.

Yeahhh, Dave, mine didn't seem to hold very long either. It wasn't radically out, but it was not really close to where they'd put it 6 mos. before. When I talked to the place that did it before (Phoenix Performance in PA), they said it just seems to be a characteristic of the car.

I have always been told that there is an Alignment for performance and another Alignment for tire wear. I have always specified the tire wear. I have always gotten over 30,000 miles on a set of tires.....

For '07, the front is the same but the rear is a little different:
Again from GMAutotech:
For the front, 05-08 is the same. The rear is different (almost identical) for 05-07...
FE123 camber is -.45+-.50 camber cross tolerance is 0+-.50

info
all i was trying to show you is if you keep going by (gm auto spec) is that you are going to wear your front tires faster and you will keep spending more money on tires! for tire wear they need to sit flat or close to it.

Here's what I have been running for 10,000 miles now, including a 5,000 mile trip out west and a 1,500 mile trip up to Canada and back. The trick is to run 0 toe if you want any decent camber. I have NO abnormal tire wear at all, and I am running -1.0° of camber on the front!! The combination of non-zero toe and more aggressive camber can cause "scuffing", which will prematurely wear out tires.
