Question Best STi alignment settings?

I'm getting my car re-aligned after an idiot rear ended my STi. What alignment settings should I ask for -- within the stock settings. E.g., "max out the rear camber", etc. they I did a search.

Stock settings are:

Front
Camber -0.30 degrees +/- 0.45 degrees
Caster 4.50 degrees +/- 0.45 degrees
Toe-in 0 +/- 3mm

Rear
Camber -1.40 degrees +/- 0.45 degrees (note: manual says 0.40, but it's apparently a typo?)
Toe-in 0 +/- 3mm

Any suggestions would be helpful.

I hate to be the search police but, SEARCH!!!!!

But to anwser your question, maybe as much camber in the front, 1.5-2.0 neg?? That would be fine for tire wear, zero toe all around or maybe a tad toe out in rear so the back end comes around a little better. Rear camber in not adjustable.

I did a search. Do a search on STi alignment or STi settings and you won't find recommended settings!

Nope. All the stock settings are different according to the service manual. E.g. WRX caster is 3.35, STi is 4.50, rear camber is 1.30 vs 1.40. Etc.

The service manual page can be found if you do a search.

Vortech's alignment suggestions sound reasonable. They are similar to mine.

But... why do you want to change from the stock settings? What do you want to change about the handling?

well if you searched then you'd know that caster is not adjustable anyway. And so what if the stock rear camber for WRX and STI is diff, you not going to adjust it either!!!!

just to re-inforce what konekiller is saying, handling and therefore alignment is a pretty personal thing. you should evaluate your needs before you start changing things.

What is it with people who think there is a 'best' this or that?

The best suspension, exhaust, tires, brakes, tire pressures, alignment, yada, yada, yada.

Every choice has a downside and an upside. The truth is... the factory settings are the best overall compromise. Deviate from them only with careful thought and open eyes.

What is it with people who don't read?

The factory specs have some leeway +/-. E.g., should toe-in be +.3, 0, or -.3? All of these settings are "factory spec". The question was "What alignment settings should I ask for -- within the stock settings?"

It'd be nice if people read more than the title before posting.

Ahhh R Diamond, forgive me. You did say within the stock settings.

So, unless you are trying to accomplish some alteration of the handlind of the car, just put it to the midpoint of the spec. You can adjust from there if you feel the car needs some improvement.

There is a good logical argument for not doing anything radical after a big bump, too. You need to see if the car is all tidy.

I would have them do a FULL alignment, thrust angle and all.

And again, forgive me for not understanding the entirety of your question.
