Don't feel too bad Opticon, Pedders is backordered on Camaro coilovers now.
I guess it is a good sign that a product you have taken the time to research and select is also the product of choice for others who likely also have taken the time to research before making their selection.

The factory setup seems to have visible negative camber already... and I'm not planning on having to change it. The sidewalls should tuck perfectly into the fenders. But you never really know for sure until you drop it. When the front suspension compresses the angle of the control arms may shift the rim outward slightly.
We should all know by the end of next week. Pedders is battling a supplier issue at the moment but is being very communicative. Yay for great customer service.

This is probably why I'm feeling a bit of a floating sensation from the rear end over grooved highway surfaces. I had it with my Mazda 3 as well (very noticeable negative camber) with the stock tires, but I'm actually feeling it a bit more with these 225/45/17 tires I'm running.
Is this something that can be adjusted by an expert (I wouldn't attempt it) or do I have to accept it as "just the way it is"?

When I was under the fenders I scoped out the setup knowing I was going to be throwing coilovers on it. I did not see the typical slotted hole or a cammed bolt on the strut assembly. If there is a camber adjustment on these cars I have yet to find it.
The thing about your problem is that I've never heard of reasonable negative camber (tops in) doing anything but ADDING lateral stability. Another thing I noticed under the sonic is a very visible amount of toe-in on the rear tires. That should technically promote straight line stability and eliminate the wandering symptoms you describe. I doubt the factory alignment spec (if correct) is creating your problem.
How wide are the wheels that you put those 225s on?
EDIT: Nevermind I found your thread. I actually suspect your tire choice is to blame. Your Hankooks have a reputation for spongy sidewalls and delayed response. Seethe Tire Rack test results on that tire and keep in mind that the entire test group are "value performers".

Lets say I found a good deal (which I did) on some 5x105 wheels that are 8" wide with a 42 offset.
My stock wheels are 6.5" wide with 41.5 offset and with a 19mm adapter, they sit right where I want them.
If I wanted the 8" wheels to end up where I got my stockers, I'd have to add 19 mm of spacer right?
Would re-lugging with studs long enough to reach through 19mm spacers (not adapters) and mount the new wheels be safe?

Nope, other direction. If the offset is the same (or in your case only a half millimeter different) then the center of the rim will mount in the same relative position. The extra rim width will be split evenly between the inside and outside of the rim. 8" wheels will poke 3/4" (19mm) more than 6.5" wheels.
So just make sure you have 1.5" of space on the inside and lose the spacers.

Thank you. I spent a better part of my day getting wise on offset math and you are right.
Furthermore the rims I'm looking at are 8J width, which is like a 7.5" standard.
So without spacers, they will sit 6mm in from where I have my stock ones sitting with the 19mm spacers. This is my final answer.
Unless someone can poke a valid hole in my estimation.
I can live with 6mm less flush as my rear tires are already scrubbing fender.
