" LOTS OF AIR TIME" doesn't help the coils either. They tend to sag after bottoming out a few times. Since there are no additional bump stops added to any of the lifts I know of, Calmini, OME, RRO, etc, the coils or shocks are the only limiting factor to the suspension. When the coils bottom out it does some damage to them. I've wasted a couple of sets that way. I actually went from OME coils to Calmini coils to get the STIFFER spring, while everyone else seems to want the softer OME's. With a winch bumper, winch, skid plates, and rock sliders it actually rides BETTER on the Calmini coils!
