Default Need help with STI suspension/cusco tops alignment

I just got back from having my car aligned and found out that it appears that the factory camber bolts do not appear to adjust STP struts appropriately due to the larger bolt holes on the strut housing. Because of this I was only able to get -1.6L and -1.4 R negative camber with the cuscos full in. Prior to addition of Cusco adj camber strut tops I was at -0.8 and -0.9 up front. The tech told me that the holes on the STP struts were bigger and thus did not allow as much push out from the camber bolts.

So I ask the wizards here....what is up? I thought I was supposed to get up to -3.0 with these Cusco adjustable plates (yes the strut tops are on correctly).

FYI- I have the full wagon STI/SPD spring/strut combo.

Either somthing is amiss or I may need to invest in camber bolts that are more eccentric to get the strut bottoms pushed out more and result in more negative camber.

Help!

Wow...why do you want so much negative camber is my first question.

Second, when we installed Cusco camber plates on a WRX sedan, we were careful to zero out the plates when the tops were tightened on, so that stock camber was achieved with the plate adjustment set at zero, effectively. I don't know if we were crazy or not, but it seemed to make sense at the time.

William's car is a wagon and the Cusco tops are mounted on the front struts. All measurements mentioned in the post are for the front struts.

I got sedan takeoffs for my wagon and I had to elongate the top hole to get more neg camber. I simply ground out about 1/8" of the inner most part. The camber bolt doesn't work for **** any more though. You just have to position everything where you want it and then tighten everything in place. It may not be the best way, but it works. I have -1.5 in the front with sti top mounts.

Just a thought, but the sedan has a wider frt track than the wagon. Since the top mounts (strut towers) are the same (I think), this would give the sedan more neg camber at the same settings on your Cusco plates (maybe the difference between the 3 deg advertised and the 1.5 deg you got on your wagon). That said, -1.5 deg works quite well for street use. Race use is another story . I believe you can get a little more neg camber if you switch the adj bolts to the lower strut mount hole. Good luck

Yeah, -3 in the front of my wagon is awesome in autoxing! It's totally neutral. Unfortunately, I don't know the details of your setup, so I can't help.

On the front of a MY02 sedan - On the alingment rack, the adjustment range of just the cusco camber plates was more than 5 degrees (almost 6), and the stock camber bolt offered almost 1.5 degrees of adjustment.

If the slot for the camber bolt in the housing bracket on the strut is too large, then you should have too much slop, and you're fine. Just position the strut where you want it manually in relation to the housing, and tighten the two bottom bolts down.

If you had -.8 camber in the front with STi tops, then you should be able to get to *at least* -3.5 degrees now with the camber plates.

On my car, with the bottom camber bolt pointing straight up (neither positive or negative) and the cusco camber plate most of the way negative (but not maxed out), I'm at -3.2 degrees.

Default thanks gang!

I appreciate the feedback.

Yes, I am auto-xing and would like -3.0 to really get the car set right!

I think the comment about wagon track being narrower might make sense if the strut tops location are identical...longer hub length would do it!

I will try to ask some experts at the auto-x track today. I'm thinking getting the bottoms out further is the key since rounding out the holes towards the middle will only get me a little and possible weaken the setup.

Does anyone with a wagon have the cusco tops? I'm sure that the 1/2 inch drop with the sti suspension reduces the bottom angle (think geometry).

Any more feedback will be appreciated :-)
