Thanks, Edit. I figgured things out. .

 

your probably gunna need to test fit so you know how close you can get to the springs. but if i were to guess im betting the offset would need to be around 0. just remember 25mm of offset is about 1 inch. so based off the factory rim and offset, if you wanted to push the extra 2.5" of width towards the fenders you would end up with about a -16mm offset.

 

haha offset around 0?!?!?!?!?!? no way in hell

you're doing everything backwards dex

you'll want an offset around 60-70 for the front and around 50 for the rear to sit in the stock location (i don't have time to do the math) if you wanna sit out more than that you'll just reduce the offset.

but what dex said is completely wrong, disregard his post

 

with a 60-70 offset (if they even exist) you will definatly hit the springs. do you understand how offsets work?

 

right... stock is +48... on a 7" width, there is no possible way to add 2.5" and have it fit INSIDE the fender. a 0 offset would stick out 3" from where the stock wheel is that is not right. a 9.5 will be nearly impossible to fit inside the wheel well which is what i was saying you'd have to go with a 60-70 offset just to get it to fit inside the fender. a zero offset will have it stick way outside the fender, maybe a compromise around 40 would be good but i doubt it would fit.

 

Here guys. It's interactive and might help you both out. I think I Might have it figgured out.

that doesn't help at all as it doesn't take into account where your suspension / fender are.
