Quote from official ARB reply: "Unfortunately we have no information on fitting the OME912 or OME913 springs to the Isuzu Vehicross. The OME912 springs were designed for a 2 door Frontera and the OME913 for a 5 door Frontera. Both are variable rated coils with the OME913 having 30mm more free height than the OME912."
