Searching around I've found some information, but nothing I would call truly definitive.
I've got a Saturday appointment with my alignment shop for my new GS.
The only real data I've found is settings recommended by DSC Sport for use with the aftermarket MSRC controller.
I don't have one of these controllers. Someone in those threads said that you could use those alignment specs without the controller, but not specifically that you should.
Are the DSC Sport Street settings best for a stock GS without the controller as well?
Car will be street driven, mountain carving, etc, won't see a real track.
From the DSC document:
STREET/OCCASIONAL TRACK – Optimized for daily comfort and reducing tire wear. Suitable for occasional track days.
Camber -1.2° all four corners
Toe -0.5mm all four corners
Caster: +7.5° Front, +0.7° rear
Does this look good for "aggressive street" specs that won't cause excessive tire wear on a completely stock car?
I just had my 19 Z06 aligned to the DSC Sport settings... I do not have the controller and may never buy one. My factory alignment was all over the place.
I havent gotten a chance to really push the car, but I feel like it tracked better and turned in a little better with the new alignment.
The rear caster is the important one to stress as it has been noted from the factory to be flipped from what it should be. It also requires a special tool to measure as the alignment racks will not measure it as rear caster is not adjustable on like 99.9% of vehicles.
Although they do a lot of stuff, this shop's real specialty is alignment and they did my C6.
I mentioned in email that I've read that rear caster on C7's can be hard and might require a special tool and all they said is that they could do it. I'm sure they've seen plenty of C7s by now so I'm guessing they can do it but I guess I should really make sure to clarify that point further.

Thanks.
Not to me it doesn't.
DSC clearly states that those specs are for occasional track use.
If you are never going to the track, then I would adopt street settings.
Camber should be closer to zero in the front, if not at zero.
That's my opinion.
Something to consider is getting your rear caster checked and adjusted before you commit to an alignment. GM dealers should be able to help with the right caster tool and digital angle gauge.
Here is my street setting for a FE6 GS. I initially set my rear caster at 0*, but consider up to .7* bi-laterally as a more accurate rear caster anywhere in that spec (0 to .7 is fine). I am currently changing my last setting back to street (see pic) and ran that with last year with minimal wear on both AS3+ and PSS, I have two sets of wheels.
Is -1.2 going to cause excessive inside wear on the street?
Yep.
Here's something you might want to do.
Go crank the steering wheel all the way to the right. Now get out of the car and look at the left front wheel.
Without any measuring tools, just your naked eye, you should be able to see the top of the tire is tilted in.
There is negative camber built into the steering geometry (for the outside tire) when you turn.
Now ask yourself how often you are going to go around a corner, so fast, that the tire rolls over onto the sidewall, or just plain loses grip.
If the answer is never, then just set it up like a normal street car, because that's what it is.
I pretty much love this.
The guy could have got the rear a little closer but the front is really good in my opinion.
It's a good alignment shop and they do a lot of Corvettes. They found three settings completely out of spec and the car only had 600 miles on it so it came that way from the factory.
It's amazing how out of whack things are from the factory.
We've bought four new Corvettes over the years. After a few hundred miles of careful driving for breakin and no curb-jumping, every one of them still had at least one alignment parameter that was outside of even the sloppy GM tolerances.
For a warranty alignment, GM requires that you have at least "x" (500?) miles and less than "y" (1,500?) miles. A friendly dealer will tell you the numbers. Then you tell them that the "car wanders at high speed" or some such, and request a warranty alignment. The two dealers I've used would set any alignment numbers I wanted, so long as they were within the GM specs.
Not to me it doesn't.

Hey PatternDay Trader.
I am interested in specs for my C7, street use only, occasional drag at the drag strip. I want the flattest rear tire foot print and a set up that creates less drag front and rear. I never do any corner carving and no high speed pulls. Car has factory tire and wheels. I will make any ride height adjustments before hand and have the car aligned with a full tank of fuel. Thank you for your help.
