I was thinking today, how would the alignment be effected with this swap? There is no need to alignment a solid rear end... at least the 05+ but i would assume an IRS would need to be aligned in the rear. I don't know of a way to tell the computer on the alignment rack that the car has a solid rear end other then just ignoring the back end.

Wouldn't this rear end swap change it quite a bit? Furthermore, if you have say 18x10 on the rear and 18x9 on the front, you couldn't rotate the tires anyway. Double trouble.

Anyone that has a rear end swap wanna weigh in on this?

 

You're correct on the offset rims and tire rotation, but having a solid axle makes alignment that much easier. You simply use the rear as your base, and align the front off of it. Too easy.

 

Here is another question about the solid rear axle.

I know the hangers would probably be different, but could you use the standard GT cat-back system since it's basically the same rear end?

 

Yes you can. It's a straight swap. The only issue I had was the brake hoses. Took just a little bit of bending to get them to fit right.
