You can try to zero it out all you want, but if you've run out of adjustment you have two options:

1) find more toe adjustment
2) run less camber

right, but what im asking is whether or not the tech's statement is in-line with other spc arm user's experiences. ive been led to believe that at my current ride height, i should have been able to hit factory rear alignment specs with only rear control arms.

You mean more camber? You typically run out of toe adjustment removing camber faster than adding it.

All depends how much camber you dialed out with the arms. A 1.3" drop probably put you at about -2.3* from the drop, if you dialed that back to about -1* I'm not shocked at all that you ran out of toe adjustment range.

I did not install the included toe bushings. I am on Sportlines (-1.4" all around). I am running -1 in the rear. My toe was not an issue.

your experience seems to be on par with others that i have read. i decided to bite the bullet and purchase spc toe arms. i had some amazon points left over so it ended up being the best solution to my problem. i felt that using the offset bushing would be too much of an issue when/if i sell the car.

i should have them installed and my toe corrected in a few days.

As I will soon install the SPC LCAs too and potentially could face the same issue, I am curious why you think it's an issue to use the SPC bushing?

Thanks

About the original post. No issues setting my SPCs and no issues with slipping even after hitting lots of potholes and dirt road silliness.

If the next owner doesn't know about it and they want more camber then it'll be an issue since they won't be able to get the toe properly set.

It's also pretty annoying to have to swap out a pressed in bushing.

The way I understood the SPC bushing was changing the adjustment range? Like if you are at the end of (or out of) the adjustment range with the stock arm, that you can bring it back to center so to speak. Is that a wrong interpretation?


Most people who lower and don't install LCA at all, don't have toe issues with stock arm and bushing. They usually come out with about -2 deg camber.

Is it correct to assume the problem is more likely to occur if you try to stand the wheel back up to e.g. -1 deg?


My desired rear camber adjustment range would be around -1.7 to -2.3 deg (with corresponding increase in front camber as well). Am I likely to face problems with that?

It's also pretty annoying to have to swap out a pressed in bushing.

I have to install the Whiteline Roll center correction ball joints anyway too. So I'll need a solution to that anyway. Yes, it's the part I presume could present the most hassle.

That's the correct interpretation. The toe bushing is only included for if you run out of adjustment range. Which generally only happens if you try to stand the rear camber up to -1 like stock.

I went to -1.9 in the rear, toe adjustment is slightly off center as expected. Absolutely no issues with a performance alignment. I also tried to stand the rear camber up to -1.0 and I maxed out the toe adjustment correcting, so I can see how people have run into issues with getting factory tame street alignment.

Sounds good.

How much camber do you run the front, -2.5? -2.7?

I'm at -2.6 but I'm on snow tires so I can't comment on the effectiveness. I do have a LOT more front grip than before though, it doesn't just understeer relentlessly.
