That's part of the reason why I'd identify this as only heat checking. Cracks around the same areas in the non-drilled areas confirm this.
Also note that the drilled holes aren't in the same place on the inside and outside faces. Another reason why I wouldn't worry so much about cracks propagating all the way through.
Don't get me wrong, the brakes on this car are amazing. I was just hoping to get a little more track time out of the rotors before replacing. The Boss 302 brakes I had on my 03 Cobra lasted about 12-14 track days and were half the price.
I wonder if carbon-ceramics would've been cheaper per track day... ;D
I'd still use them is all I'm saying. Like Nick said, "use at your discretion"
