alignment specs for C5 Z06
I am doing an HPDE at Lime Rock and would like to get the car aligned more suited for the track.
What kind of alignment specs would you guys recommend?
My shocks are 04 Z06 Shocks and my tires are Falken Azenis RT-615.

Assume you are a street-driver with occasional track events.
That's what I was ... tho my street time is increasingly "to and from the track"
On streets, I moved my front to 1.2 neg, target 6.9 caster, 0.0 toe
Rear: 0.8 neg, 1/16" (.06 I think) total toe IN.
When I started running Nitto 555RII's as my track tire (still driving to track), I kicked my front up to 1.4 (other settings same), kicked rear up to 1.0 neg; and moved rear toe IN to 1/8" (.13 I think) total.

You're not going to get more than -1.1 or so camber in the back, unless you lower the car. Perhaps a bit less. The things I noted when I changed to -1.5 front, slight toe out, -1 back, slight toe in, max caster all around:
1) Braking straight line was a little more exciting. Not a great deal, but I noticed it.
2) Turn in was MUCH improved, and I seemed to be able to get power down faster than with the stock alignment.
3) Tire wear on the street seemed not to change.
Now, I'm having to make another change. My outside edges (rear tires) are wearing more than my insides when I'm running as fast as I can. I need more camber in the back, but the car, in stock trim, can't do it. Camber plates are the answer, I think, and likely 1/2" or so lower, all around to maintain rake.
