I'd say you got lucky.
Mintex Reds may be nice street pads but not for any heavy duty use - I learned the same the hard way when I used Hawk street pads on the track, I developed fading into lap #2 and had to choose *very* conservative brake points from then on, took half the fun away.
I have seen completely discolored (almost burned) center caps from the excessive heat that these kind of pads could not dissipate
About machining your rotors: I guess you don't have an "S" as cross drilled rotors can't be machined. Otherwise hard to say without having a gander at the rotors
