Homemade Spring Offset kit

Here is the thing. I considered doing the spring relocation, actually planned on it later on in the build but I got to measuring on my car and of I did the relocation I'd have to move my entire exhaust(dont want to I like were its at).
Like you said I would need to do a mini tub dont want to do that either I want my car to remain factory in the metal. I'm not a good enough body guy to attempt a project like that.
I would also have to get different rims with more backspace to put the tire in instead of out. That's a no go I already have the rims I want to use.
And I really dont want to cut and weld my frame. And I really dont think I'm gonna need that much tire anyway. It's just a stockish 360. I may change my mind on that after I start driving it haha.
I would like to run like a 255 60 tire.

You can run a 275 60 with the right wheel and no relocation.
