The aftermarket rotors do not use the bolts. I believe that the bolts were used only at the factory for assembly purposes. The wheel essentially holds the rotor on.
Good call on the upgraded rotors. The overseas junk never really has held up for me.
While your at it, I suggest a brake fluid flush and replacement using synthetic fluid. The Star has a tendency to fry the fluid. I had my brakes go out on me on a hot day due to the fluid cooking.
