I'm only on the vw 30mm lower springs, as I don't want to be too low for ground clearance reasons. The back sits a bit higher than the front as I rarely have any weight in it. I'm happy with it though. I'm going to see how it goes and if I don't like it, I'll put my 18" back on. I bought the wheels second hand for the same price as the tyres, so it's a relatively cheap 20" experiment/experience
