Scud , since you are not worrying about getting the bolts out ( of the damaged wheel ) but the rotor off , you can use a drill bit as the same size of the hex of the capscrew . Drill down into the screw about 3/8''. Then take the tool and try removing the bolt . This will twist off the head of the bolt. Do this ( as long as it is successful ) to the remaining bolts . You will be able to lift the rotor off the wheel .
