Rear negative camber and adjustable arm
 

Hey guys, I am having an issue and need some help. I recently got lowering springs on my car. I have been reading around and i believe i need some attachments to ensure my tires and suspension work correctly. I went in to get my car aligned today and not only did the place fuck up my rim but didnt get my car aligned correct. Below is a picture of the before and after specs. I am told by a couple people and reading online I will need a Adjustable rear control arm on my right side to account for the negative camber. My questions are:

1.) can you guys give me some opinion on some good fairly priced adjustable rear control arms for my lower (1.4in) scion frs.
2.) Also, I was told that the scion frs does not have adjustable cambers and that when you lower the car it will cause major tire wear. I am interested in getting some adjustable camber (do I need on back 2 or all 4) if you guys could give me some good options at a decent price for my car.

Any other things I might need to be aware of by lowering my car would also be appreciated. Thanks

HERE IS THE PICTURE GUYS

Hi @Chase1996,

If you have done some research, our cars do not come with any camber adjustment. It should be easy to find.

Anyways, to resolve front.. use SPC camber bolt. It's about $30-35, but it looks like you won't need front adjusted.

For rear, budget friendly option is SPC rear lower control arm. About $220 for the pair. The alignment shop didn't screw your alignment, they have no option to adjust any camber. It's easy to replace the rear arm. Replace them and maybe talk to the shop again and see if they can adjust the rear at lower price.

Good luck.

The guys at the shop bent my springs causing the camber to go out of alignment, they were not able to re align the back bc of there msitake.

I appreciate the info though. I will check into those, once I get the lower controlled arms what will that bring them too about? and will that have any effect on the handling using the arms.

How did they bend your springs?

This makes no sense. To "bend" a spring would require heating with a high temperature flame or massive amounts of leverage. Neither of which an alignment shop would be doing. They might have bent the control arm.

I highly doubt they bent anything. These cars are notorious for the rear camber being about a deg different side to side. And that only gets worse when you lower it.

I'm using 12mm camber bolts in the rear lower control arm, inner mounting point, to adjust camber. The bolts were something like $20 on Amazon. If I were you, I'd also get camber bolts for the front.

These low amounts of camber won't wear you tires out. I know its counterintuitive, but its true.

Even if they did bend your spring, I don't think the camber would be affected like that.

The guys at the shop told me that the spring had been bent causing something under there to be out of alignment to the point where they could not fix it.

They "bent" your spring and left your toe in rear like that? Wtf run far away

There's nothing overtly wrong with the toe, there's just nothing great about it either. It just looks to me like OP took his car to a shop that only aims to get the car within spec and throws it out the door/didn't know what they were doing, and gave him an excuse as to why they couldn't fix it.

Op, I know it's gonna cost you money, but take it to another shop, preferably a performance shop. I'd bring either a set of 12mm camber bolts to fix the rear camber, or a set of rear lower control arms, and give them a goal for the rear camber. I'd say -1.5 deg would be a good spot for you to be at. I'd also bring a set of front camber bolts and have them add in as much negative camber to the front as possible. You'll likely only get about a degree, but that'll be a large improvement over the factory 0.

Bent springs wont cause camber changes - period, on the front or rear suspension. A ride height change because of a bent spring may cause a change in camber, but that would have to be a massively bent or destroyed spring, which you would have felt and heard. The rear suspension is defined by Subaru as a double wishbone suspension. If a mechanic that is doing your alignment cant tell how it works, you need to run away very fast. The front is a McPherson strut suspension, which is pretty common.

Rear camber on double wishbone is controlled by the length of the A-arm, which on a stock 86 is not adjustable. Toe is adjustable however, but only within certain limits, and this may be the best they could get it. Regardless toe is in spec. I would say that your rear camber numbers are normal for a car that it lowered like yours. If you notice uneven tire wear or bad handling I would say go for adjustable arms. If not, leave it alone.

This is a good rundown if you want a better explanation:

Pretty sure mine had cam bolts in the toe arms when I got it... still got adjustable arms, gt spec to be precise.
