If I am not mistaken...
The GXP and the GT the wheel cannot be used. As mentioned before; the rotor/caliper clearance (not sure about GT model) but also cannot be used on the rear Wheels. The differential has to run 2 identical wheels.
I read somewhere on the forum that will screw up the differential if 2 different diameter wheels are used. At the front wheels would be ok but again, I think the Rotor/Caliper assembly will interfere.
