I've seen a lot of posts in this forum comment on ride height as a function of springs, bump pads, and to lesser extent slight variations caused by wheel/tire diameter and shocks. I have yet to come across a consistent pattern. Whereas one person has bigger wheel well gap in front, mine was bigger in the rear before shock change, about the same after. I think you simply have to experiment between front/rear spring pad thicknesses until you achieve a level ride. You can search for "bump pads *mm*" to find postings on different spring pads and their effect on ride height.
