Quality bolt-on hubcentric spacers aren't dangerous. They're quite popular with the "hellaflush" and "stance" guys to get the wheels out to the edge of the fender, and to change lug patterns. You will probably have to find a spacer company that can custom make spacers to fit your hub. Double check the torque after driving it and you'll be good. We have a '06 Trailblazer SS and are thinking about using 1" bolt on spacers to get the wheels out flush with the fender edges.
