Looking at the camber bolts on my lower control arm. They are set slightly different.

I would expect both both to be set equally otherwise the wheel will effective move forward / back in the arch.

My new 285 fronts rub slightly on the front arch. I wonder if it's because of this.

Time for an alignment shop!

On my FRS, the fronts initially had no rubbing issues. When I went to track alignment specs with -3.0 front camber, they rubbed during full lock. Which was fine for track, but annoying for drifting. Anyway, that could definitely be the reason why one of your wheels is rubbing. For my FRS, I checked the wheel well and saw scrapes where the top of the wheel was rubbing the frame.

They can be set different if you need to set the caster. Still a good idea to get it checked.

Very good point.

Does anyone have the stock alignment settings including caster to hand? I'll google it later if no.

FWIW. I talked to one of the tech reps when I was at the NCM Bash a couple years ago and I asked about camber as I do not track my car and did not like the wearing of the inside of the front tires. And this was after using the setting from PFADT street performance. Was told that 0 degree camber is fine. I had mine set to .1 . The car handles fine and tire wear is even across the front tires. Mine is a base C6.

Thanks Guys.

I have the car booked in at a place called center gravity. They have an on car shock dyno which it will be going on. Should be good to see whats going on.

I don't think those camber adjusting bolt markings are any indication of what the actual camber is set to. It's just a visual aid for the alignment technician during adjusting.

correct. It is a reference mark.

Camber can be set differently given the steering design.

I've done alignments on Jaguars that I own. They set camber for North American right side drive roads differently than left side drive roads. Camber on the passengers side is more than drivers side 3/4* and 1/4*.
