Caster
For my C6Z I requested a camber increase to - 1.6 front and -1.2 rear. I noticed I have the following new alignment:
I also lowered the car 1" to 4" ground to frame after installing coilovers.
Left
camber -1.51
Caster + 9.97
toe 0
camber -1.54
Caster + 9.58
toe 0
Rear camber is -1.17 both sides
Rear toe in is 0
Is this to much caster?

I didn't know you could get that much. The numbers I've heard are 6-7.5 but that was limitted by higher camber numbers...-1.8 to -2.0.
There must be a point of diminishing returns caused by high caster on the sharp turns resulting in reduced contact patch and difficulty in turning the wheel. But I have no idea where that would be. Others will chip in I'm sure.

all castor does is give you more camber in the turns. So, too much castor would be the same thing as having too much camber, ie too much heat/wear on the inside of the tires.
You're going to have about 25% more camber gain when turning, than a car with 7deg castor. That might be a good thing, might be too much. Wear and temps are the only way to know
I agree, usually you can't get that much castor unless you have pretty low camber numbers.

I would think you'd want some rear toe in. Why did you go with zero?

The answer is I don't know why I went with a zero intoe in the rear. I'm learning alignment and would try it if I knew what it would gain me.
Also, if I knew which bar the adjuster was I would prefer to do it myself. ok, I got two flats being 2/6 turn for just under 1/8" toe in, I'll look around. Thanks.

The C6 spec is different than the C5 alignment spec. Caster can be +7.9 degrees + or - .6 degrees for a total of + 8.5 degrees. Rear Toe is 0.0 degrees + or - .2 degrees. Since you are a novice I would be careful on making the rear toe adjustment. If you do it wrong the car will not only wear the tires but dog walk on you. The extreme caster with -1.5 camber probably is achievable by the lower car. How are you able to drive the car anywhere if it has been lowered 4 inches? You would have to be careful not to run over stones on the road being that low.
