Got my stock '18 PP aligned today; a lot of R/R neg camber
 

Hi all!

I understand that stock, these cars only have toe adjustments in all four corners.

I hit a pothole and popped my 225/45/17 WinterSottoZeroIII of my front left wheel. Luckily, being the reasonable person I am, I had a summer set of wheel that I promptly put on.

Maybe it was placebo, but I thought the car handled worse than I remembered. I got the car aligned today.

Sure enough, the front left had a weird amount of toe out while the front right had a reasonable amount of toe in. I got the guys to get the toe to be more or less zero everywhere. :D Again, perhaps it's placebo, but i think the car drives better now (initial turn in seems better and more consistent going either way)

Strangely though, the rear toe was all messed up before the alignment (even though I didn't go through the pothole with them) and the rear right still has a lot of negative camber. Does Subaru ship cars from the factory with this much variation in alignment? :confused0068:

By the way, the guys at Firestone (this local one has a decent reputation) say that the front left suspension looked fine; I personally didn't see anything strange either when i was switching out the wheels.

Cheers!

I dont think i've seen a stock car be in the 2's. Mine was like -0.5 one side and -1.6 the other though, so there's a lot of slop from the factory. For a car marketed as it is, and with as much potential as it has, they sure cut a lot of corners at the Subaru plants.

You can try the SPC rear control arms, they're cheap and easy to adjust.

Short answer, yes. Factory alignment allowance can be wide


Per the Repair Manual
Front: 0.00 +/- 0.75 Deg
Rear: -1.20 +/- 0.75 Deg
Left-to-Right Difference (both F and R): 0.75 Deg or less

I started a thread in this section about my rear camber after lowering 1” on a 17 brz without PP. PP height is somewhere between standard brz and lowered 1”.

I also had a ton of rear camber, almost 3* on one side. I installed Moog rear lower control arms (SPC parts in a Moog box for $35 less). SPC camber bolts in the front to add in some camber.

I am much happier with the look and handling, the Moog arms were $180 for the pair on Amazon.

2*58’ is just shy of 3*, we use minutes instead of decimals.

I stumbled upon this thread after some searching.

I recently lowered my '18 PP on RCE "yellows" and added SPC front camber bolts and SPC rear LCAs.

My alignment is fine up front: -1.5 each side and 0 toe.

The rear numbers are a bit off. To get a slight and even rear toe in, the right camber came out to -1.3 while the left camber resulted in -1.8. I thought that was a huge variance, but the shop told me it should be "fine" and that the camber adjustment affected the toe and vice versa.

Has anyone thought of or tried SPC rear toe links to "fix" the rear camber asymmetry?

BA9092: indeed, adjusting toe affects camber and vice versa. But our cars have toe adjustment stock. I'd get rear LCAs to add camber adjustment for rear but not bother with adding aftermarket rear toe links.

They're correct, but the tech is either not knowledgeable enough to equalize each side or just lazy.

Literally just aligned my car last night and the rear takes a little more effort.....I think I adjusted each side 3-4 times to get it "right"/even on each side.

An aftermarket toe link will not change how the toe moves the camber. You need rear LCAs to adjust the camber. See my post above.


The rear camber is not adjustable. Setting the toe evenly is much more important, you would never sacrifice toe adjustment to even out the camber. Classy to assume the tech is either not knowledgeable enough or just lazy to not adjust something that isn’t adjustable. :thumbdown:

Unless you think front camber should be II while rear camber is /\. Then by all means, throw the toe out the window and make those Rota 19s tuck. Because stance bro.

He said he already added the spc lower arms. tech should be able to easily align them to be even. i am betting they didn't want to "waste" anymore time on it. you should find a better alignment shop BA9092.

Reread the first post before starting someone is not "classy".

Apology accepted [emoji6]

Too many people posting! In that case the tech was either incompetent or lazy. Probably lazy, eccentrics are part of the job.

Thanks guys!

I'm going to try another reputable shop before looking into rear toe arms.

So, is evening rear toe (in, in this case) more important than even rear camber? I've seen quite a few guys with uneven rear camber, up to .5 difference. Is that acceptable then?

Ideally you want both of them even. It just requires a little more work (no extra parts in your case).

Uneven camber can cause a pull and weird driving characteristics.

Uneven toe can cause uneven wear on tires and weird driving characteristics.....assuming it's off by a far amount.

Ultimately your better off with a discrepancy between camber vs toe.
