Zero to ~+.1 camber up front on a stock STI is not uncommon.

as far as stock adjustment..... if i remember correct, you cant do much with the rear without camber plates or a c/o system that can adjust.. (my KW's are slotted)..

BUT.... the front on my 06, without camber plates... was able to be adjusted to -1.7 max... i would figure you would at least be able to do that with the 08?
when i picked up my 06, you could visually see that it was positive in the front..... and it was.
as far as setting up the car, after many different setups and essentially needing to increase the rear negative to conform with my 18x9, +45's.... i ended up with the following:
front -3.0
rear -2.4

i found this to be an amazing setup on the track and ended up running it at all times.... no matter what some people thought of the degrees, i loved it..

so to close.. i would figure you could at least get -1.5 in the front on your 08?

I appreciate your comments, but none of them really apply to the 08 STI.

within my ramblings...... more or less what i was sayin is that i would be surprised if you couldnt get at least -1.7 on the 08's stock components...

That wouldn't be too horrible I guess. I wish they would have built in a bit more adjustability though. And added some on the rear for sure. I plan to use mine in stock class for autocross which is why I'm asking

My ESP WRX had -3.2* camber in the front and it was pretty well balanced.

If I have time this Sat.
I will see what I can do myself maxing out the front camber and then reseting toe to zero.
I have a decent homebrew method to do this.

1.7 sounds a helluva a lot better than zero.

My first auto-X will be on Feb. 10th BTW.

We'll see.

you people and your auto-x........

get your whips out on the track, already.... or up a canyon at least.....................

eitherway, enjoy the 08.... i'll be with you soon.

I need to win trophies to feel validated as a man, so track days and canyon carving doesn't appeal to me. Plus track days are expensive and there aren't a lot of canyons in Philadelphia.

Good luck Ploney, I´m with you, please keep us posted on your camber changing experience. I think that small change in the front (from zero

to -1.7) will give you a lot more grip up front, thus reducing oversteer (for a more neutral feeling). I myself would like to give it a less dramatic change in the front for more of a track or high speed testing and then work from there (my track days are a few months away still), ANYWAY, godspeed everyone

I think you mean understeer. Adding negative camber upfront usually reduces understeer.

In general, more camber upfront, equals more grip, less understeer. Some people also like to reduce rear camber to promote better rotation of the rear.

Who made that mistake? If you reduce rear camber it can help the rear end rotate better. Obviously, that requires camber bolts on the rear since it isn't adjustable in stock form.

Was that on the stock front suspension, including stock camber adjustment bolt? Most 05 owners couldn't break -1.0 deg and you are almost another full degree above that. I didn't think anything changed in 06+, except maybe the caster. The most I could muster with camber bolts upfront (didn't put any in the rear) was -2.0. It made a huge difference.

Was I really vague? by "mod" i meant "minutes of degree". Sorry. You have it right. -0.7 nominal with the plus or minus tolerance. I don't think you can actually get over -1 unless they tweaked the hardware up front. I'd love to see what people are actually able to dial in on this car.

ya, what you said...

i dunno.. i could have read it wrong...

the -1.7 was on stock, 06 suspension.. could have been 1.6? but no less than that.... not sure what the difference was between years.. though from what you say.. it does sound like there was a change?

Yeah, it's crazy if you got -1.6 on a stock setup. The best my 05 could get was -0.95, with most 04s getting over -1.0. I didn't realise the 06+s could get more. Did you buy your car new or used?

That was my experience with an 05 too. I had to use camber/caster plates to get my current alignment of ~6.5 degrees caster and -1.4 degrees camber up front. The STI is getting caster numbers that approach BMW geometry now. Interesting.

For those of you keeping track of this thread (digitalfiend), again, in my last post, I meant less UNDERSTEER (sorry, english is my second languaje

). ANYHOW, I spoke to a friend of mine who does some racing here in Mexico (including a lot of AWD) and he told me that as a rule of thumb in awd cars, you should try to achieve a 2/1 ratio negative camber between the front and the rear. This is, if you have ~2 in the back, have ~1 in the front. It sounds good to me. I´m gonna work with that ratio and the maximum stock and work from there.
Salud!

I think you have the numbers backwards... -2 up front and -1 in the rear would reduce understeer and help the car rotate better.
