I'm selling my front OEM rotors after having new rotors and brakes installed this weekend. I probably only needed pads, but I guess you live and learn.
The rotors measured at 28.75mm and 28.81. For those you don't know, original spec is 30.0mm with recommended replacement at 28.0mm. A good friend of mine did the work and the measurements, so I trust they are accurate.
Discounted OEM rotors from Sewell cost $395.88 total. So with an average remaining life of 39% (@ 28.78mm), I'm selling these for a rounded off $150 total.
Maybe some of you track guys could take these and beat them to death.
