Well Mine were originally set to 2 when I picked it up, it was ok for just me (im 220) but when i had my girlfriend on back (shes about 130) goin up my driveway it would bottom out at the edge where it meets the street. When i moved it to 3 it looked as though it sits a tad higher but i didnt measure it or anything and no we dont bottom out at all. I have heard the progressive kits will lower you about 1 in.
