Very few, if any have them. They offer no real benefit to braking. They will actually increase the amount of time to stop because the surface area of the rotor is reduced.
in all honesty if you built a jig to maintain symetry, used a drill press, and chamferred the holes it should work, but IMHO it is more trouble than it is worth

If you've got the money to do something like that, then you probably have the money for a baer or brembo brake kit that'll brake better than any drill job you'll ever do.
its a bad idea you will wind up ruining the rotors/brake pads, maybe even the calipers... just buy some they are not good for braking only for looks anyway.
