What about these alignment specs?
I know this question has been asked alot but I was wondering what you guys thought of this setup on my 1985 vette, it has some minor weight reduction, all poly bushings, bilsteins, Z51, camber brace, 275's up front and 315's on 11" rims in the rear.
I drive this car on the street alot and also do alot of drag racing and some autocross racing. I want it to handle good on the street but I have mixed opinions as to what negative camber to run on the front and rear being that my tires are much wider in the rear.
Front:
toe 0"
camber .50 negative
caster 6 positive
Rear:
toe 1/8" in
camber .50 negative
Is this too much negative camber for my 275/315 tire combo? I want it to handle good but I don't want alot of uneven tire wear.
Please give me your opinions.
Thanks,
John

http://www.vbandp.com/instructions/h...ruct/align.htm I went with the advanced street on my 86, and loved the way it handled. I thought it wore the tires too uneven though and since I have sawblade rims it was a chore for me to have them rotated. I have since gone back to DD.

Running the wider tire in the rear I would add a little more negative up front. Maybe -.7 or -.8. I road race mine and have the same tires you do. My specs are:
Front:
toe 0"
camber -2.2
caster 6.5 positive
Rear:
toe 1/8" in
camber -1.7
With my springs, shocks and sway bars this provides a very neutral setup.

I assume because so much of my time is spent in corners here in the foothills. Was planning on increasing negative camber all around next alignment, which will be soon. If I'm not mistaken, aren't your toe settings about the opposite of the advanced street settings? How do you like that and why? Thanks, Chris
And yes, his toe is backwards. A lot of autocrossers use a little toe out up front for better turn-in. The car is a little darty with that alignment on the street tho. Most road racers go with 0 toe up front. A little toe-in in the rear will help stabilize the car at high speed.
