I have an '02 Coupe with the base suspension springs, Bilstein sport shocks, Z06 swaybars, and is lowered about an inch. I want to get the car aligned, but I am not sure what specs I should use. I've read some things on the forum in the past where people were talking about camber being affected by lowering the car, and adjusting the factory alignment specs to compensate. I seem to recall that someone discussed using the Z06 specs on a coupe that had some suspension modifications. Oh also, I don't know if it factors into the equation, but I also switched out the run-flats for a set of Bridgestone S03s. Any suggestions on what specs I should take with me when I get the alignment done? Thanks!

If you are running non-runflats, and you are, Z06 Specs or something similar will greatly improve your handling but shorten tire life marginally. Runflats can't handle negative caliber, regular tires can. I've driven a couple with regular tires and Z06 Specs, it makes a BIG difference in handling.
I got this from somebody here. Unless you are going to spend a lot of time on the track I would go with OEM perferred. I also have the 03s and while they are a great tire they don't wear well at all. But great on the track!
I just lowered my car by cutting the front busings and using longer bolts. When I got my car aligned I took it to Big O tires - they have a Hunter laser alignment machine and the guy hit the specs posted above dead nuts ! I asked him to increase the camber a little and he did it until I said stop.
Unless you have a VERY good guy doing it the "analog" way - go with the laser alignment. It's precision and very hard for the guy to screw up because it is checked by the program.
I was using -.8 (front) & -.5 (rear) camber on my 2001 Coupe. That was with runflats (before I got the CCW's & Kumho's). It didn't cause any problems and still wore the outside of the tires when autocrossing.

Al,
I didn't know who to credit! Thanks!
I put it on a word document so I could send it to my buddy who has a Z06 and wore out a front set of tires in 6K miles!
Re: I need advice on alignment specs. (TooManyIDs)
Did he wear the outside edges?
If he went through a set in 6K miles, I would guess that moving from the stock setting to the moderate setting may not help much.
Is this track or autocross use? Is it used on the street, too?
It was the outside edges with 3 autocrosses and 3 trips to Gingerman Raceway which is a 2 mile roadcurse and is a killer of brakes and tires. Also drives it on the street as a weekend cruiser.
I noticed that you cut the front bushings and used longer bolts in the rear. Is it possible to cut bushings both in the front and rear without having to get longer bolts? Also, is the wheel well gap the same on your car at the front tire and rear tire? Does the car look level, or is it higher toward the rear (like the stock cars look)?
