2019 GS wheel alignment question: I've been told that the GS comes from the factory aligned for track use, which causes early and odd tire wear. I was told that I should have the car "re-aligned" to Sting Ray specs--and that would alleviate potential tire wear (too much wear on the inside of the tire). When I ask my local dealer--they ack like it's something they can't do--but then again, my dealership isn't the best lol. Any thoughts? Thanks

I'm not sure if there's any difference in alignment between the different models (since you can track a stingray also). You'll want to ask for a "street or track alignment". It's up to the tech whether they have any idea what you're talking about or not. When I got an alignment I told them I don't track the car, it's for street use only.
There's a bunch of threads with people posting specific alignment specs that they got.

Most dealerships will check the alignment and if it is anywhere close to the mile-wide factory specs, they will call it good. I suggest finding a shop that specializes in alignment and ask them for a "street" or "tire-friendly" alignment. Just for reference, I had our `19 Grand Sport aligned to the following specs:
Front Camber: -1.0
Front Caster: 7.5 to 8.0
Front Toe: 0.01
Cross Camber: 0.2
Cross Caster: -0.5
Total Toe: 0.03

Rear Camber: -1.0
Rear Toe: 0.02
Total Toe: 0.03
Thrust Angle: 0.00

When I bought my 2019 GS new, after 500 miles I had the alignment checked at my trusted alignment shop and this is what it said. Looked perfect to us so nothing had to be touched. I now have 3612 miles on the car and the tires have worn evenly across so I guess it's still good. I know I know I don't really drive the car.

Thanks for your response!! I'm going to have it checked out for sure

No, it doesn't come from the factory with a track alignment. It has an aggressive alignment but it is nowhere near what the recommended track alignment is. The recommended track alignment is printed in the OM.

The Factory Service Manual lists the recommended street alignment settings, FE1 through FE4 are for the narrow body Stingray/Z51 cars and FE6 and FE7 are for the wide body GS and Z06 cars:

Check the maximum camber numbers shown in the chart and then compare them to the recommended camber numbers in the track settings which are -2.0 degrees front and rear and from side to side.

One thing to think about when adjusting alignment to increase tire mileage. The more street-like the alignment the less crisp the handling. If you didn't purchase a Corvette for the zippy handling then maybe you purchased the wrong car.

Our `19 Grand Sport with -1.0 camber front & rear handles like a dream. No, we don't track our convertible, but the roads between home and the Oregon Coast can be a road course under the right conditions.

Take to an alignment shop that know what they are doing, Yes, it will have an aggressive alignment from the factory and my Cup 2s wore out in 14K miles.

My challenge is finding a shop that knows what they are doing but yes--will do! Thx

Find a Shop that has a Rear Caster Tool. Alignment Machines Cannot Measure or Display Rear Caster. If Rear Camber is Adjusted Rear Caster Will Change. So they have to be adjuster together.

I have used the attached DSC alignment specs on my 19 GS from day one with great results. Good luck.

Thanks for all the information. I think I need a less aggressive alignment, and all weather tires.

I don’t mean to offend you but your comment, “then maybe you purchased the wrong car,” that classic was classic Corvette enthusiast. You made my day with that, thank you.
