Wait a second: they show Active Curve as a regular, stand alone option now, but, in order to get it, AirMatic is "required," but AirMatic is an SPC option? It has to be a misprint and must be the other way around, with AirMatic being the regular option and Active Curve being on the SPC list.
Either way you're going to pay the Special Order Fee.
