Hey, just wondering if anyone out there has wheel spacers?

I wanted to put some on my car, what size/length should i get for the wheels to sit about an inch, maybe a little less right outside the well. Looking to do all 4 tires also.

 

Hope you realize that when the wheels sit outside the wheel well, the tires stand a good chance of getting shredded by the fender when you drive over big bumps.

 

why not just get the right backspacing on wheels

 

Well this is why im asking, what do yall think i should do? I really want to put wheel spacers on but not sure what size or how i should do it.
