Need Alignment specs for '02 Z06
Hi,
I've lowered my car and will be taking it in to get aligned tomorrow morning and I need the alignment specs for an '02 Z06.
Is there a difference between the '01 and '02 Z06 specs?
Thanks,

I don't have the stock spec in hand, but the alignment kind of depends on what your into. The best set up for autocross, is a bit "twitchy" at very high speeds. It just depends what your goal is.

Re: Need Alignment specs for '02 Z06 (rschiltz)
This is the factory specifications for the ZO6, both '01 and '02. These are different than regular C5 specifications, so some shops alignment machines may not have the right databases loaded to show this:
Front Individual Toe +0.04 degree +/- 0.10 degree
Front Sum Toe +0.08 degree +/- 0.20 degree
Front Individual Caster +6.9 degree +/- 0.50 degree
Front Cross Caster within +/- 0.25 degree
Front Individual Camber -0.70 degree +/-0.50
degree
Front Cross Camber within +/-0.25 degree
Rear Individual Toe -0.01 degree +/- 0.10 degree
Rear Sum Toe -0.02 degree +/- 0.20 degree
Rear Individual Camber -0.68 degree +/- 0.50 degree
Rear Cross Camber within +/- 0.50 degree
For more aggressive track/street use, increase front individual camber to 1.0 degrees, and rear individual camber to .8 degrees, while reducing front toe to .06 degrees, and rear toe to the minimum (.01 degrees). This is a very drivable setup and increases mechanical grip noticably. Some auto-crossers will get even more agressive, setting rear camber at 1.1 degrees and front at 1.5 degrees, and toe-out the front at .02 degrees, but this will cause a lot of tire wear on the street, and make the car a little "darty" on regular surface streets, but makes them really grab on tight courses on marginal surfaces.
Hope this is what you were looking for. :cheers:

Re: Need Alignment specs for '02 Z06 (TooManyIDs)
Thanks guys for all the responses, this is exactly what I was looking for. I don't race my Z06 but still want decent handling for the street. It sounds like I'll use a moderate setup.

If you never take the care to a race track, you will not gain anyhting with the higher camber settings, but will experience greater tire wear. For street-only duty, best bet is to stick to the factory algnment ideals.
FWIW - I just finished going through several sets of worn F1's to see how most are wearing, with a tire specialist. The comment made was that the ZO6 driven on the street exclusively, seems to exhibit quite a bit of camber wear, even at factory settings, both front and rear. It was also noted that too many owners are over-inflating the F1's, evidenced by high center tread wear (over-inflation) in addition to the inside edge wear (camber). 30psi is where they should be cold.

Probably true for street duty.
On the moderate settings, the wear pattern on my Kumho's is still higher on the outside edge. That's with autocross and track use.
