Sorry man but I have no idea.... but I do know the wheels have to be off. When the wheels are off, the rotors simply slide off the studs. The rotors are held into replace by the tire when you torque down the lug nuts. If the rotors don't simply fall off when the wheels come off, give them a bang with a rubber mallet a few times to free them up from the hub. Watch the videos above. Youll see how the rotors just come off...
EDIT: Let me rephrase this. Remove the caliper. After the caliper is off, remove the brake pads then the brake pad housing bracket... THEN the rotor falls off. Sorry, I forgot about those 4 extra bolts. Just watch the video above LOL
