Wondering if anyone with autocrossing/circuit/daily driver 240s could get some tips on my trip to the alignment rack on Wednesday. Guy who is doing my alignment is veteran autocrosser. Looking for specs for good tire wear, stability, etc etc.

Anyhow, I recently had RUCAs and Tein camber plates installed and went to someone with less alignment experience (found out when I got there) and this is what I left with:

Front camber: -2.4, -2.5Caster: 7.6Front Toe: 0.02Total toe front: 0.05

Rear camber: -2.5,-2.9Rear toe: 0.13Total toe Rear: 0.24

I've been told to go -0.08 toe in the rear and to turn down my rear camber to -2.0. Since the front experiences a lot of camber gain during turning? (Or was it the rear.. can't remember)

As far as the car's handling, there's more pronounced understeer mid-turn, steering is a bit more loose feeling (if that's possible, I went in with 6.9 caster to start,and I know bumping it up makes the steering more heavy). Kind of twitchy rather..

Turn in seems to have improved but I'm basing my exp. on twisty backroads and not autocrossing (haven't had time to hit an event yet this year)...seems as though I can enter turns at a higher rate of speed now.. which i like..I've embarrassed a few expensive cars on the twisties.

Any thoughts about my specs and how to alleviate the above 'issues' would be much appreciated!

p.s. Don't want the drifter perspective, I'm not maxing out my camber as I do not run coils so -2.5 is about as much as I can get out of the front w. out rubbing.. or so we found. So I'm not interested in "hella tyte camber" but more about how the car is reacting to driver input (Setup is 225/50/16, AGX+Suspension Tech linear-rated springs)
