How to get to this 'stance'

Don't be surprised if you find out that it's not a leaf spring suspension on that car.

That looks to be at least a 28" tall tire, I'd actually guess taller, on a 15" rim tucked to wear the top of the rim is flush with the fender lip.

I'm betting ladder bar or 4-link suspension. I'm not saying it can't be done with leaf springs and lowering blocks, I'm just saying not to assume. Especially since no leaf springs are visible in the photo.
