Gotcha. Thank goodness I didn't order the 5100/885 setup then.
So, now the question is....King or Icon Coilovers.
Damn, this is getting too expensive...
Progressive vs digressive
"For example, when the valves open or close, depending on the shock and valving design, the rate at which the damping becomes softer or stiffer per unit of shock velocity increase depends on if the valving is linear, progressive, or digressive. As the name suggests, in linear valving the rate at which the damping changes with the velocity of the shock is constant. If the valving is progressive, the rate of change of stiffness increases as velocity increases; and if the valving is digressive, the rate of change of damping gets less as the shocks velocity increases."
