Default Rear tires angle problems

I've had my car on jack stands for about a month, and finally got it back on the ground today (had to get some replacment tires, long story short I lost three rear tires in a week and got tired of losing rubber, so I got it home and threw it on stands until I got some more tires)

Well obviously the front tires need some air in them, but the rear tires concern me. It's not TOO noticable, but if you look at the car from the rear on the ground, you can see that the tire angle is off. Rather than being like this

They are more like this

Now that is exagerating, they aren't THAT bad, but that's the angle they are looking now. Would that be a toe-in or toe-out? Either way, I want these these to be straight again, as the Camaro is receiving 315's as soon as the winter is over, and I don't want them to wear unevenly. 315 drag radials aren't cheap as you all know. Can I fix this myself? Adjustable panhard rod and adjustable lower control arms started the whole problem in the beginning, can they be used to fix it? Or can an alignment shop fix this? I plan on 12 bolting this thing in the Springtime, will a new rear fix it too? I don't want a brand new 12 bolt to be off like my current 10 bolt is

Maybe I'm not understanding you but it sounds like your axle tubes are bent.

The tubes are fine, thankfully. I'm not sure which it is, but the rear tires are either at a toe-in or toe-out from what it seems. I drove the car around the block a few times, it drives in a straight line just fine, it turns just fine without wheel hopping or anything. After I got it back home it looks a LOT better, maybe it was just how it sat on the ground for the first time after it sat for so long on the stands *shrugs*

Dosnt sound to good to me bro. I am under the impression that you cannot adjust the way the rear tires sit without a lca relocation brackets. Did you happen to lower your car, but neglect to the the rlocation brackets? If not then I would think your rear is screwed up pretty bad. Because we have a standard rear (dont know the technical term) you cannot move the rim angle, like you can on an IRS. If it isnt the relocation brackets, then I dont know what to tell ya. I hope somone else has some input.

If the tires are not parallel, you would have to have a bent axle housing. Are you sure about this? Measure the toe with a tape measure, don't trust just eye-balling it.

Does it look something like this?

Ok, im a noob when it comes to suspension so dont make fun of me for this
But woudnt that be considered a negative camber? To my knowledege cars have thier wheels rotated in an outward possition for, in some cases better handling, or a different handling effect. From what ive read, the farther out your camber is on your rear the more the car will over steer. And the farther out it is in the front the more you will understeer.
Now i dont know if f-bodies are like that from the factory or not. Did you buy the car new? If not do you know if the previous owner did any mods to it?

what u describe with rear angle is called negative camber. not seen on a live rear axle only on a lowered independent rear, adj by fitting a caster camber kit.As was said previous for a live rear to have this "u need a bent housing."

I was thinking the same thing. Your housing would almost have to be bent.

Fortunatley, it doesn't look like that

I drove the car around the block and I did not have any sort of noise coming from the rear. When I got the car back in the garage it looked fine, I think it may have just been how the car sat after it was dropped back down on the ground after being up so long. It did come down quicker than normal, so I think that may have something to do with it. I'll go take a look, and if it doesn't look good still, I will take a picture

Okay problem found. It's because the adjustable LCAs pushed one side of the rear end and made it sit funny. Rather than being perfectly like this: -------- The driver's side was pulled to the front of the car a little. No big deal, I'll have that sucker aligned right before Springtime

Thanks for the help though guys
