I am finally going to get my IROC aligned properly. This IROC is street-driven, autocrossed weekly, and see an occasional track day. Since I won my first event (in F-Stock) a few weeks back, I've been getting the same feedback from the local "top drivers" - get the car aligned correctly. A couple of these guys ran 3rd gens years ago and I plan to ask them what they ran.

Even so, I am interested in your opinion as well.

It has been stated that "generically", the following settings are good for autox (regardless of car!?):

Front:
Camber: -1.0 to -2.0
Caster: maximum adjustment possible
Toe: 0 to 1/16" toe out per side

Rear:
Camber: -1.0 to -1.5
Toe: 1/16" to 1/4" toe in per side

In addition, on this website, the following numbers are suggested:

Stock Front settings with 15" wheels:
Camber: -1.0 to -2.0
Caster: +3 +/- 0.5
Toe: 0 to 1/16" toe out per side


Street Front settings:
Camber: -0.5
Caster: +4 (L) and +4.5 (R)
Toe: 3/64 toe out per side

Hard Street Use Front Settings:
Camber: -1.0
Caster: +5 (L) and +5.5 (R)
Toe: 3/64 toe out per side

Road Racing:
Camber: -1.75
Caster: +6 (L) and +6 (R)
Toe: 1/16 (out) - 1/32 (in) per side (course dependent)


Now, some questions:
1) What is the maximum negative camber that I can expect from stock components?
2) Assuming maximum camber, what would be the maximum positive caster that I can expect from stock components?
3) How much will the stock components let me change the rear?
4) With the information that I have (to be also verified by the local hot shoes), I was thinking of these settings:

Front:
Camber: -2.0 (if I can get it)
Caster: +6 (if I can get it)
Toe: 1/16" toe out per side

Rear:
Camber: -1.5 (if I can get it)
Toe: 1/32 toe in per side (if I can get it)

Any input and opinions are welcome.
