dirt driving - alignment

I live near Mendocino National Forest. There are over 1,000 miles of dirt roads that the public can drive on. Probably 25% of these are primo for rally-style driving. I have been up a couple of times this winter scoping it out - not driving more than 75% max speed, but having a little fun drifting through corners where there are good sight lines (don't want to take out a motorcycle coming the other way on a blind turn). Otherwise I have not raced or thrashed the car.

My problem: I did an alignment when I bought the car (new) to make it rock solid at speed. The rear alignment is now out - after only 15K miles.

Question: How often does the WRX need alignment? Rally-style driving? Daily driver?

Thanks.

what is out on the rear....camber or toe? camber is not adjustable from the factory on all subarus, but toe is. serious off road driving (ie, dirt roadin it) will cause the toe setting to slip. on the next aligntment, ask you tech doin the alignment to make sure the toe eccentric is tourqued to specs, and afterward make an index mark to see if it is slipping. the toe eccentric is on the lower control arm where it mounts to the body, by the rear diff. if your camber is out, use a camber adjustin bolt, (such as NAPA 264-36410 to adjust. they are about 15 bucks each, cheaper than most places.
if you drive the car hard, which most of us do, you need to check the align every 5-10k miles.....usually our customers do it when the tires are rotated.....cheap insurance.

camber adjustment

I just got back from the alignment shop. According to the alignment printout, the specified range for the rear wheels camber is -1.7 to -0.2 degrees. My actual before and after alignment is -3.5. The tech said he could not get it any closer.

The range for toe in is -0.15 to 0.15 and mine can only be adjusted to
-0.19.

They said something is bent. A careful visual inspection does not show any damaged parts. Will the Napa camber adjustment bolt do enough to bring it close to spec?

And thanks in advance for all advice!

is it too much negative on one side, or both? give me both side readings, and i'll check it out.....if one side is too far pos., and one side too far neg., then the rear cradle is shifted. the camber bolts should get it to within tolerences, but will still ###### see -1.5 or so......gimme info!!!!!!! keep me informed
thanks

yeah, the cam bolt should do it, bring it to -1.0, to match. almost looks like the strut is bent in.....but it should effect toe, too. that much is obvious, wheel should look like its leanin in at the top.

Well, I bought the Napa bolt, pn NAPA 264-3641 as recommended and it does not fit - too small. I will contact some aftermarket sellers and see what I can come up with.

yeah....try 264-3642, see if that'll work.....its is supposed to be loose, it is offset to allow for adjustment. sorry bout that, i think a 3641 will work, i used them........but, see if a 3642 does the trick.

the 264-3642 is for the 14mm strut bolts, ie gm, chrysler. 264-3641 is for 12mm strut bolts, and i think is correct for the subies. havent put them in my car yet, but all subies at work use them.......it helps to hav ea tool called the tomcat for setting camber. air bag placed between strut and tire to help move it to set camber. sorry for the techno babble, but thats how i am.....the bolt is supposed to be a loose fit, though, and it goes in the top hole. good luck, and keep me posted
