I don't think turning drilled rotors is a good idea, mine had small stress cracks at the tiny holes after many track days and over 60,000 miles. I thought the $110 or $120 a wheel for the beautiful stock rotors was a bargain. I've been very happy with the stock rotors and only get the overheat warning after many hot laps at the track.
