Default SPC Performance Adjustable Control Arms 72450 To Help With Toe Wear?

Has anyone used these to help with toe camber wear? I blew threw a set of tires in 2 months since I've got the car. I word at a ski hill so I drive 50km each day up and down a road with tons of hard corners. Thanks.

You have Toe wear on the front or on the rear?

First, have you done a wheel alignment anytime recently? Has your vehicle been in any type of accident where any suspension pieces had to be replaced?

SPC Performance Adjustable Control Arms 72450 is for the rear and adjusts Camber angle. When adjusting camber angle it does effect Toe a bit but is not mainly adjustable from here.

There is actual Toe adjustment on the rear suspension arms from the factory. The rear Toe IN when it compresses so it will scrub the entire tire instead of just the inner portion.

Typically for our cars the Toe wear is apparent for the front suspension due to one of the bushings designed with rubber. WIth rubber bushings during acceleration the vehicle suspension toe out and scrubs the inner part of the tire more than any other contact patch.
People typically upgrade these Front Lower Arm Rear Mount bushing to stiffer material. This is what you should be looking into replacing if you have inner tire wear on the front from toe.

I just had an alignment done but they said I would still get toe wear unless I bought these control arms. Don't think any accidents but I did not buy the car new. I have bad wear front and back. Do you know where I can get the stiffer front bushings?

Unless you crashed your car, you should have the ability to zero out your toe. You'll need to get a custom alignment and request toe to be zeroed out. Keep in mind you compromise straight line high speed stability when you do that. But since you have a unique commute, sounds like it may be worth it to you.

Or just get cheaper tires. Either way you bought a performance oriented car so expect to run through tires. It's normal--a badge of honor, even.

stock suspension? the car should have enough toe adjustment to get ~0 degrees. take your car to another alignment place, there's no way you'd need a camber arm to adjust stock suspension to stock specs. that's just crazy.

I have those rear control arms, but only because I'm lowered on RSR coils. You blew through your rear tires? Mine seem to be lasting way longer than my front tires which are shot after a short amount of time.
