That would be one axle.
Also just curious about why most think that the solid rotor/D110 setup on the front is better than the vented rotor/D90 setup. Personally I think I prefer the vented here in ColoRADo just for heat dissipation when I have a 20 mile 6% grade on some of the highways here. I was always able to feel the fade in the brakes on my old D1 on some of these descents.
