in reality the C7 is the simplest car to align. since it has rear independent toe and camber. The reason the guys had a hard time is they aren't use to setting "caster" few cars out there over the last 15 years even have caster adjustment.
Old school guys can do it pretty easy since they "GET" the concept of what caster even is, lol. 99 out of 100 cars aligned in these types of shops set the "TOE" and go so when they have to actually do some adjusting they are lost. paul
Yet the track alignment specs have no such imbalance, which leads me to believe the standard alignment is to offset crowned roads, not because the car pulls to the right.
Not all roads are crowned, and if the factory settings were asymmetrical solely for that reason there would be an awful lot of dissatisfied customers driving on the Interstate.
Here's an interesting note on the factory alignment that I have referred to in other posts. The C7 as designed by GM has a built in pull to the right, and the front camber setting is asymmetric to account for it (see the chart above, where the right front camber is adjusted with an extra -0.3 degrees compared to the left). This was pointed out to me by the race team at Pfadt Engineering. So if you have an alignment change for the track, or have one done anywhere but the dealer, be sure they have the correct numbers, or you will get that pull to the right.
Btw, my dealer only charged me $125 for a full 4-wheel alignment (I had it modified for both street and track use).

Could the difference be to compensate for the weight of a driver on the left side? On lighter cars, like Miatas, I always had a weighted alignment done, with the equivalent of my weight in the driver's seat.
Wouldn't more negative camber on the right side, make the car go LEFT instead of right?
Some alignment shops also do that to correct for the crown of the road.
Yep, the alignment specs show a car that would slightly pull left. But once your weight is in the car then theoretically the left side camber comes in a little. I did alignments for years and just set side to side the same. A long time ago we just flicked with caster on the left side to fix the crown in the road effect but these days roads are mostly different so same on each side is best idea.
