My Duster also has the Espo +1 springs. These have been on for a few years, so they should be completely settled. Just pay NO attention to the rusty quarter panel. Ill get to that soon. lol
I would leave the front as is. The rears will settle after some poundage and probably sit about an inch lower when settled. My Duster went through the same resting process with the same ESPO springs.
