Racing Alignment settings
Having searched a lot here and found some threads about wheel alignment.
But always it is "road" or "fast road" setting is talked about.
No one seems to share his super secret racing settings
Then there is more knowledge here than in the Swedish community and many more that are actually racing.
MY03 STI
265/35-18 Toyo R888
I only run track racing such as Time Attack.
Dont have all the information in front of me such as caster, etc etc.
But from memory my settings now are:
* -3 Degrees camber front
* -2 Degrees Rear
* 0 TOE F + R
But it feels not quite right. And i dont think it is right either.
Corner entry is not how i want it to be, and you almost have to throw the car around the track.
Any tips on how I can proceed with my settings?

Have you ever tried dialling some toe-in, especially up front?
Turn in will be helped quite a bit with a few minutes of toe-in both front & rear
I've ran road going Impreza's with 0°12' of toe-in, but usually opt for about 8 on my Type R hooning only car. Turn-in & overall balance is spot on with these settings
On my Forester STi (again road) I go for less toe, but some never the less
Caster is less of an issue, but should be max'd out. ~6° and with some offset bushing for 'anti-lift' will also help turn-in
As for R888's on a Time Attack car, do you get them overheating? I wouldn't be surprised if those tyres melted on a Scooby Time Attack car

No I have never tried with little TOE IN.
Should I try with 8 degrees TOE IN both front and rear?
What do you think of my camber?
I'm not so good at this with the car's alignment settings. And do not have any confidence in them local workshops.
So I need to come up with my own settings, and get it set up.
You know any good link to a sheet that i can have as guideline?
Yes, my front tire runs very hot at times.
We can not run with slicks for regulations.
There is better tires than R888 on the market. I will probably try other tires for next season.

I think you certainly need some toe-in as this will preserve dynamic in-corner toe.
A neutral toe setting will mean the outside cornering wheel will almost certainly be in a toe-out condition when pushing on mid corner.
What is your tyre wear like up front? Is it even, more inside than out, fathering etc?
Also, as far as camber is concerned it's more important to maintain temperature balance across the tyre's surface, as I don't know what the suspension travel is like on your coilovers. Do you have any pics of your car both static & mid corner?
0.08' Toe-in should be a good starting point with the camber you currently have
