Do you not know how the rotational axis of the rotors react with the angle of the hub and calipers themselves? Obviously not, otherwise you wouldn't have made that statement.
If you space the hub, and rotational axis of the rotors thereof, the way the brake pads engage the rotor will be affected.
Not sure if you have disassembled the rear of the xB2, but I have.
If you space the hub in any way, you will have to space the caliper as well. The hub, and inherently rotational axis of the rotors, are mounted on the same plane as the calipers. If any of these corresponding mounting points differ, abnormal brake wear will occur.
