I couldn't find the answer in a search, so I'll ask you guys. My brother-in-law has a 2016 Corvette Z06 with the Z07 package. He said that all Z06's come from the factory with track alignment specs. I'm not sure if that's correct or not. He doesn't track his car and wants to have his car aligned for street use. Does GM have different alignment specs for street and track use? Thanks in advance for your help.
My car came from GM out of alignment. Yes, there are different track and street alignments. If you run the track alignment on the street you will wear out a set of tires in about 10k miles. For street it is best to reduce the camber to 0 to -.2 degrees, with 0 to .2 degrees of toe in on each end.

Thank you. Do you know the exact specs by chance or where I can find them? I'm guessing there has to be a number of them. I'm not really familiar with alignment, so that may be a stupid question.
You basically want to 0 out as much as possible, here's what I've run for good street wear. The camber doesn't really come into play all that much, so even if you can't 0 it out, even up to -1.5 degrees won't be noticable. Near the end of life of the tire, the inner may look more worn, but you'll be at the wear bars anyways for the rest of the tire. The issue of cording too soon is a bad toe + camber. We put some toe in on the rear as under thrust it'll 0 out.
Thanks for posting this. It seems like the alignment specs are somewhat elusive for our Z06’s. In the C6 days, I would just go and look at PFAT’s street performance alignment specs. For the C7Z, that info doesn’t seem readily available.
The C7 came with a specific alignment when it came out of the factory. Most of the Z06s and GSs that I have played with came with -1.0 plus or minus 0.1 degrees of camber at all 4 wheels. GM does have a track alignment that is recommended when the car is taken to the track. That alignment is far different than the way the cars came from the factory. Here are the factory specs that are shown in the Factory Service Manual:
The Z06 and GS have the FE6 and FE7 suspensions.
The track alignment is:
Notice the negative camber for the track alignment is at least double the negative camber of the street alignment. Also, notice the front camber is the same for both the left and right sides of the car while the street settings have the right side camber -0.3 degrees more than the left side. This added negative camber helps compensate for road crown pull assuming the car is driven on the right side of the crown Vs the left side.
A lot of mechanics that have never worked with track-related alignments think street settings are track alignments since they are more aggressive than the grocery-getter vehicles they normally work on, but they are still street settings.
