I’m getting conflicting information from my Chevy dealer service tech about SS alignment and wanted to see if anyone had better information about this. I brought my SS in for an alignment check at 1,500 miles last week. The dealer had just had a visit by the Hunter rep who had just updated the Hunter system software with the new SS alignment specs. I was told by the tech (who was their Corvette ‘specialist’), that on the SS, only toe was adjustable and there was nothing he could do to adjust caster or camber. I read in a recent review that camber, caster and toe were all fully adjustable. What’s the true story?

Blowing smoke is what I call it go to independent shop that's what I did after they goofed up my 11 Camaro and ruined a set of tires in less than 10000 miles. My shop gave me the read outs on toe caster and camber. The only vehicle I can remember with out adjustments was chevys pickup that required a kit to adjust front end.

"Set the toe and let it go!"

Specialist? ... only in doing 100 flat rate hours every week!

Caster is pretty much fixed in the design of the Zeta suspension. It would require adjustment plates at the top of the struts to change caster--race level stuff. Note this listing (by CP) in another forum - caster plates and other suspension parts

There is an acceptable range to allow for production variation and to tell if there is something "wrong" with the car if caster is outside acceptable range. Camber and toe are adjustable.

Doug, if it's not 6 degrees, what is it on your car if it's "off"? Is it outside of the 4.75 or 7.25 range?

Tolerance shows an allowed 1.25 degrees variance, range of 2.5 degrees and still will be considered acceptable, and would not expect any help from GM.

Production variance, car was dropped/tweaked in transit (there would be other indications, I would think) - hard to say if it's not on the target number of 6 degrees.

It is close like 6 one side and 6.5 other, don't have the results in front of me my wife likes to file everything and then you have to go to her for info. In the old days this stagger was done for the crown in the road so car would track straight. I don't like this because I can feel it tracking with this setup. My corvettes drove me crazy till I had them set up even on either side. I can imagine that there is not enough play to move this around .5 just my opinion not an adjustment just slack in system. My car was done at a race shop and they changed nothing saying it would wear good. You know why I never pushed this, or I will tell you in private conversation. Just call the cell

And if only .3 front and .7 rear how much better might it handle if it were closer to .7 front and 1.0-1.2 rear.

Won't increasing the differential from front to back by (with a rear bias) .3 increase understeer?

Something else, not an SS but in my car anything under -1.2* and I suffer no adverse tire wear. I'm not familiar with the SS or G8.


Hello from sunny California. Just got back from the wheel alignment (and initial oil change). Here is a copy of the print-out. FYI, I took the specs from Customer Care (above) and apparently when they punched the SS into the computer, it listed the specs as a G8.

Seems ok, and feels fine.

Here is the alignment specs again. :)

Just let us know if there is anything else we can help with!

Have a wonderful and safe New Year,

Thank you for posting this. I brought my car in with complaint of the steering wheel being crooked. They aligned my car using 2014 Impala specs and said "You must have run over something your car was bad out of alignment."
I am on my way now to give them an education on what this car is.

I tried to be nice, give them the benefit of the doubt, and just drop my car off for service without bugging them about it. I guess I won't make that mistake again.

Camber and toe are adjustable. You can buy a factory caster kit that adds about 1/2 degree of caster. I've seen an aftermarket kit for a full 1 degree extra. My car had the toe off from the factory and it didn't track straight. I ended up going to a good alignment shop and getting a pretty aggressive alignment, with -1.3 front camber and -.75 rear camber, minimal toe, and I added the caster kit. It drives like a much smaller car with much better steering and less understeer, but I'm certainly sacrificing some tire life with those settings.
