I was actually just thinking this same thing. My stock rear springs are starting to sag a bit. So with the evo leveling kit, having the stock stubby front bumper, i sit a bit more nose high than before. So when i throw a 35in spare in the back, i know its going to sag even more. So the 1in rear spring from Synergy sounds like a good idea. And if a tad bit more lift is needed, the 3/4in spacer from the leveling kit would seem to come in handy.
