DE killed Mintex Red Box pads

[timothy]

I did my first DE October 25 - 26 and it killed a set of fairly new Mintex Red Box pads. They were installed in September and had approximately 2000 miles of mostly highway. The pads looked practically new. What's left of the front pads after this weekend is a sad sight. After two days at the track the fronts are worn to about 1/8" (3mm) and one had a chuck missing front the leading edge. The front rotors have distinct albeit small ridges while the rear are worn mostly smooth.

When selecting the Mintex I did not intend to track the car but the opportunity arose and I took it. I realize they are not track pads but is one DE really all I can expect to get out of them? Mostly I just want to make sure it's simply the wrong pad for the application and not something else that caused their quick demise. Should I have the front rotors turned before replacing the pads?
