Alignment AutoX 2005 Sti part 1

Alignment AutoX 2005 Sti
I am looking for assistance on my A Stock 2005 STi. I have AX for 7 months in A/S and can only get close to the Honda 2000 and Porsche Boxster. A/S allows no aftermarket suspension replacements other than the front swaybar, so [I]Setup and alignment are crucial[/I] .

no kidding and there are a bunch of threads if you do a search...

you will have trouble keeping up with the S2k no matter what you do, it's a better AS car than the STi IMHO, something to get used to, look at national level event results.

Let me know when you are running 275 V710's and hopefully you will read the big tire thread which will tell you how you can set up your AS STi because tires and a bar are your options....275's are fun so you should get them...lol
Perry Trice 07-21-2006 10:17 PM

I am aware of the Nat'l level S2K is all there is, but I'm not Nat'l caliber either. I am running 245 V710's but wll try the 275's on my next set. I have a 27MM Whitline FSB.
Web Foot STi 07-21-2006 10:25 PM

The short version: As much balanced negative camber in the front as possible. About -1.3 deg, and zero toe F & R.

The STi is great, but not the most nimble of beasts.

Right now the 27mm Whiteline sounds like the best bar around.
Perry Trice 07-21-2006 10:30 PM

I have as much negative frony camber as adjustments will allow, but all other specs are pure stock factory. Turn in is good with WL FSB, but it can be a beast! I had been advised to toe out the rear but I am reluctant without really good advice.
alltracin 07-21-2006 10:39 PM

Some people recommend lots of toe out everywhere. Whiteline recommends 0 toe all around. I run 0 toe and it's about as much as I want to have to handle on the street. Bumpsteer was nonexistant with stock toe in, and is a little aggrivating now. This is an '06 WRX with RE070s, so take the comparison for what it's worth.
Perry Trice 07-21-2006 10:45 PM

I will give it a try. I have run my Re070's in a few events, including AX schools they are a pretty good tire even with over 25K on them.

Also allowed replacement dampers that keep the geometry the same as stock. Not sure what's available for the STI, exactly... maybe Koni inserts in WRX housings?

perry - I would echo this. It sounds like your headed in the right direction, maybe a little less camber in the back to aid rotation and the toe suggestions are valid and many have tried them.

good luck - I too enjoyed AS for a year on street tires

have fun!
mykrrrr 07-22-2006 09:59 AM

Front camber - As much neg as possible
Rear camber - 1.0 neg or less
Front toe - Zero
Rear toe - 1/16 - 1/8" out

These were suggested to me by Keith Casey. They worked well on my STi wapped GF wagon.

I won a couple events in an A Stock prepped STi in SM Street Tyre but I don't know the specs as it was my buddy's car. The STi had a Strano front bar on it. Not sure if that's bigger than the WL but I think it is.
AndrewSS 07-22-2006 11:41 AM

You should be able to get to about -1.0

I got like -.9 in my fronts and rears were at stock -1.4
(which dont have much play, maybe +/- .2 if you mess with em).

I have to say - unless you really like A-stock at your local region, which I did last season - which is why I stayed in AS, as well as just doing a season basically stock to learn and whatnot... you really should think about moving to STU and then you dont need to go crazy modding, just do camber bolts or plates to get the car handling much better then really saving your tires... might be something to think about, I know when I did my first autox with my proper alignment from my front plates I was wondering what took me so long, plus my AD07's are wearing pretty evenly.

Terry,

Might want to read this thread about the Strano bar... not making any judgements, but might as well see what other folks have to say:
(skip to the last few pages, about the breakage issues)

It is quite possibly all just coincidental, but just saying "forewarned is forearmed". Since the few reported breakages happened with DOT-R's, and you're running them, it may apply to you as well.


Oh, and Welcome to Nasioc Terry, I'm James, the guy with the CGM '05 STi at the local autox's .. glasses, gohtee, met you at the school a while back (and we've talked in grid several times). You definitely have a tough row to hoe in AS vs. Hedderick and 'Roger the Real' etc..., my sympathies :)
makofoto 07-22-2006 12:40 PM

I didn't realize that Whiteline published US AX'ing alignment specs!

Perry ... are you using the DCCD in Auto or full rear? For newer drivers Auto is probably better. But some experienced drivers, especially ex road racers, prefer AX'ing their STI's with the DCCD in full rear. This car make the car a bit oversteer'y for newer drivers. I wonder if adding a bit of rear toe IN, like many of the high horse power rear wheel drive cars do, would help get the power down on corner exit without too much oversteer. The strength of the STI is it's power.

It really helps to start opening your steering as soon as possible to avoid late mid corner push.
BIGSKYWRX 07-22-2006 07:43 PM

He's in a 05 so WRX struts w/ Koni's are out :(

I'd play w/ toe a little- generally a little toe out in the rear will help w/ rotation, a little toe out in the front will help w/ turn in. OE specs are pretty wide in regards to toe- you can run close to 1/8" toe out/in and still be in factory spec. Be advised that toe other than 0 can add a little to tire wear, the further you stray from 0 the more wear. I'm currently running a mm/side out in the rear w/ no ill effects on tires ( i rotate often too though).

You don't have a lot to "play" w/ so I think I would try some toe different toe settings- the DCCD adj is a good tip as well.

James,

I am running the Whiteline BSF36XXZ 27MM bar with rodend style endlinks, so far so good. See ya at AX.

The CDDC is much smarter and faster than I am, I have tried around 75% rear and really found little change in the handling. Perhaps time and experience will change that.

That works for 04 STi but no go for 05/06/ soon 07.
SoloSTI 07-23-2006 07:19 PM

I have an 04 STI which I have been AX for a year now and have had no luck beating an 03 EVO. My car is basically stock (suspension) except for another setting I drilled on the factory sway bar (rear) the car now oversteersa little in early turn in and still pushes out of the corner. The car feels twitchy when I power out. Also handling seems to change a lot when I have a full tank of gas or less than a 1/4 full. I run with the DCCD in auto mode.

I will be installing a Racecomp adjsutable camber plates up front and STI pink springs before the next race. I run in SM and use either Kumho s700 (slicks) or Yokohama Advans A032S (wet)

Are there any alignment settings that have been proven to work with this set up?

I need to beat that EVO (it's my brothers)!
The_Wolf 07-24-2006 09:16 AM

Ohlin has a set of shocks that can be used in an AS STI....not a cheap option though.

I am running AS on my 06. I am running a Strano FSB and 275 v710's all around. Car is great, but I need to push harder. I have also been getting my a_s_s handed to me (in the dry of course) by certain s2k's, vettes and locally by last year's AS champ and his wife :D

Lots of front camber, half of that in the rear and 0 toe. We run -3 front, -1.5 rear with 0 toe and the car feels great.
SoloSTI 07-25-2006 02:50 AM

I'll have this done tomorrow. Do rear camber plates help? When my camber plates are set to zero what alignment specifications should they be at? My car is a daily driver.

Thanks
SkylineR35GTRx 04-23-2007 03:55 PM

Hey I'm trying to run A-stock also and I was wondering if this alignment sounds good... -1.3 in the front (or max) 0 toe in the front, and -1 in the back and zero toe in the back.

I'm going to a shop to get this done and I don't have the money to play with my adjustments...does this sound like an ideal set up? Thanks.
rankink 04-23-2007 05:15 PM

On a 05 STi in A-stock like others have said you need to be running the whiteline 29mm front sway bar or the Strano 32mm bar. I ahve run both bars on my car. They strano has the better turn in (better bar), but quite a few people have broken their mounting tabs on the front control arms. Myself included. My opinion on that is the endlink mounting �boxes� for the bar would move to much against the softer aluminum and slowly caused the tab to weaken.

Anyway, you want max neg camber in the front which most people get 0.9 � 1.3 using stock bolts. For A-stock you can not use camber plates or camber bolts. I prefer 1/16 � 1/8 toe out on the front for better turn in. The rear you are stuck with the stock neg camber of about 1.3 or so. I run 0 toe as I have no problem rotating the car with either tire pressures or throttle.

You can run 275/40-17 r-comps on a 05+ STi on either the stock wheels with a 3-5mm spacer or 17x8 wheels with a 48 offset. These are the way to go over the 245/45�s. Cat back exhaust for some weight savings is another legal mod. For struts the only options besides completely custom made DA�s is the ohlins SA�s, but they run $2000 a set. Not for the budget minded autocrosser really.

Other than that I would recommend a good harness that mounts into the stock seatbelt anchors to keep you in the seat and let you focus more on driving.

The STi is very course dependant vs. a S2K. Give it a power course, or a lower traction course on asphalt and the STI can beat a S2K. Assuming drivers are equal. The damn speed maintainence courses are where the S2K shines over the STI.
SkylineR35GTRx 04-24-2007 01:37 AM

Wait, how come we're stuck with the -1.3 camber in the rear? Just wondering.
SkylineR35GTRx 04-24-2007 01:42 AM

Should we just keep the rear camber stock?
rankink 04-24-2007 06:58 AM

That is about what the car comes with stock and there are no adjustment bolts stock in the rear. You basically have to keep it stock per the AS rules.
