I asked my shop to do recommended GM track specification for my car but ended up with something different. I specifically worry about the toe. Is this OK? and how will it change the handling of my car?
Print out was not available (out of ink) so I am attaching pictures of the front and rear plus a picture of recommended specs by GM.
Thank you for your help.

I think it's fine.

Looks like they basically maxed out camber and got toe close to zero while keeping it positive for stability… quality work.

Looks good to me. Camber is matched side to side and likely maxed out for stock parts which will give you optimal performance on track. You would have to convert toe measurements from in (inches?) to degrees to compare exactly. Zero front toe is recommended on these forums for better tire wear...that's what I run and you are very close to it. If it doesn't track straight with your hand off of the steering wheel you can go back with a fine adjustment bolt (available from Lowe's) and ask them to remove 0.1 degree of camber from the front left and reset toe to the same value on that corner but it is likely a very slight camber difference that might not even be noticeable without seeing accuracy to another decimal place to confirm.

For rear toe, going for the max amount in the range from your second picture is recommended by others. I have tried both 0 and near max and the difference was not very noticeable to me...maybe slightly less tendency to oversteer on track.

-2.5F on OEM hardware is great! Not everyone is able to get more than -2.2/2.3


Toe is fine. I like to run .125 on mine for turn in on track.

0.04" of toe on a 26.8" tire(front) is 0.085516* of toe angle
0.04" of toe on a 27.2" tire(rear) is 0.082458* of toe angle

Thank you all. Makes me feel better.
I am going to Watkins Glen next week.
