Mine does that as well, but the film inside is more yellowy and the
terminals were burnt pretty good. It didn't start until I put the MSD box
and coil in. Showed it to my dad, he said his used to to that back in the
day (in his racecar) also. Apparently it's some sort of ionization from the
high energy ignition system that leaves the residue. After 15K miles you
couldn't even tell that my rotor was black to start with. It was pretty sad
looking.
