Alignment Spec's anyone?

Can anyone recommend alignment spec's for my 01 Z06? I just bought a new set of Kuhmo Ecsta V710's and am heading for the track (NHIS Road Course) this weekend. I have lowered the car almost as low as it goes. I will be changing back to street tires & wheels and still want to drive on the street. I'm mostly concerned about getting the most track time out of the tires.

Thanks!

I run 4/5 HPDEs a year so I want track performance but don't want to chord street tires in 3000 miles so here's what I run.

Front

-1.3 degrees camber per side
+6.9 degrees caster per side
0 toe (very very very critical to low tire wear)

Rear

-.9 degrees camber per side
1/16th" toe-in per side or 1/8th" sum toe-in.

Car handles much much better yet I still get very very long street tire life. The fronts do wear a little more on the inner 1/2 but I still get over 20,000 miles out of them.

Hey Brian,

What is the stock alignment range for comparison sake? Is it in the FAQ?

Dog... that's because you're running R2's!!! Normal street tires will last. I run Hoosiers at the track.

Steve... I think the front is like -.7 degrees camber max, but like all cars it's an "acceptable" range, not specific specs. So... in short I don't know all the stock specs.

It is really easy to reset the toe on these cars at the same time you are changing tires. I used to run zero toe on the street and then crank in 1/2 a turn of toe out into the front on the track. Just mark you tie rods to the zero position and match mark the links and you can reset it in a couple of minutes. Nail polish (rob your wife or girl friend) or a bit of white paint make it easy to see where the zero point is.

Latey I have been running about 1/2 a turn of toe in per side on the street and then crank in the 1/2 turn of toe out at the track.
