If still under warranty, tell the dealer it "handles funny at high speeds" or something like that, you can get one free alignment under warranty.
You must be between x (500?) miles and xx (5,000?) miles to get this.
Components of alignment specs:
Caster makes no difference to tire wear.
Toe in/out can eat the edges of your tires in a hurry, get them to set just a tiny bit of toe-IN and it becomes essentially 0 when driving. Best tire wear and handles well.
Camber (actually, negative camber) has a big effect on cornering grip and moderate effect on tire wear. The closer to 0 camber, the longer your tires will last but at the expense of cornering.
My take on camber: 0 for best tire life. -.5 is a nice cruising setting compromise. -1.0 is for aggressive driving.
There is some variation in individual cars, some GS/Z06 cars can't be adjusted to 0 camber. Either accept the lowest you can get, or there are a couple of easy mods that allow down to 0 camber.
Enjoy!

You haven't told us:
What model C7 your have.
How you drive it- track rat or grocery getter, or something in between.
Any mods to suspension/wheels/tires.
Your goal for the alignment- best tire life above all, or best cornering performance above all, or something in between.
With that information, people can make appropriate suggestions.

here is a good article on what caster, toe, etc effect on a automobile - I enjoyed reading on caster effects steering - Caster angle settings allow the vehicle manufacturer to balance steering effort, high speed stability and front end cornering effectiveness.
Increasing the amount of positive caster will increase steering effort and straight line tracking

To decode it for you-
Caster: 7'- 8' but equal on both sides
Toe: +.1' or as low as they can get it and still be toe-in; not neutral or out
Camber: -.5' all wheels except .2 less on left front to counter road crown. Tire wear should be fairly even, you can increase the camber to -.8' for better cornering but somewhat more inner edge wear on tires.

Alignment question
SO I just picked up my new GS. The dealer was kind enough to align it to the FE1 spec for me. Compared to my 2015 Stingray I sold the steering seems mushy and it seems it wants to wander a bit. I am wondering if I made a mistake asking for the alignment. My question is for those that have done this alignment have you noticed a difference in handling from before the alignment to after the alignment. Better/Worse..
Thanks!
Thanks!
