If I get a set of 39.5 Iroks, what's a good lift height to go with it? Currently I have 4" springs all the way around. Not happy with the fronts because they are a 1/4" narrower than they should be, and they are stiff as hell. I figured I would do an ORD shackle flip in the rear and then a new set of good springs for the front, but I'm not sure how far to go. If I did a 2.5" shackle flip, reused my rear 4" springs, and got 6" lift springs for the front, would that suffice or should I try to get 8" total? I already have to trim the front fenders anyways, so that's no big deal. I remember hearing that 39.5's aren't truly that tall anyways???
