Looking for recommended alignment specs for stock hardware.

what tire?

Hankook R-S3

Would like more camber as I've previous tracked cars with stock suspension and I keep rolling over the sidewall to the point where there would be paint on the sidewall.

I've read else where Toe should be 0 all around and Camber should be:

F: -2.0 to -1.5
R: -1.5 to -1.0

Is that close? Would F-2.0, R-1.5 be too much camber for the rear? I imagine with Evo's and their struts, the more camber in the front, the better.

What about stock caster adjustments? Can you even adjust stock caster front or rear?

-2.0 up front
-1.2 in rear

I would think would do you well to start

You'll have to work to get that much camber front but it can be done. R-S3 is a very good tire for the track lots of feedback and grip. Start at 36 cold go to 42F-44R hot.

You can get a little bit of caster adjustment front by moving the cradle but it's not worth messing with.

my first few times on rs3's i ran 32 cold and got them to 38ish hot. this past weekend with a 32 base pressure, and an experienced evo guy/instructor flogging my car, his biggest observation was a lack of front grip. the tires had heated to 40+ psi.

42-44 seems little hot imho.

but this also depends on tire size and rim size.

What kind of readings were you getting with your pyrometer on the fronts?

I went for 35 hot all day at the track. Was faster than when I went 38 hot.

A light read for you then.

Couple locals run rs-3's at 38 cold and 41/42 hot. Less then that they were rolling the sidewalls on stock wheels/size.

if you push a little they will heat up more than that. remember pressure goes up about 1 psi for every 10 degrees Fahrenheit and the R-S3 like to run at about 170 Fahrenheit.
