My suggestion. Have them set at 2 3/4-3.0" of lift. Put tires/wheels on that you decide on. If you want to lower it...then lower it. It is easier to lower than to raise, both can be done, but easier uncompressing spring. For the back just decide, do I want it level...then get the 2.0" RB, a little rake...get 2.25" RB, more rake 2.5" RB. Simple!
