I agree with what has been stated above about the rotors having plenty of life for at least a couple more track days. Those cracks are called either "heat checking" or "crazing" and are totally normal for a car that gets tracked. If any of the cracks can easily be caught by running your fingernail over the crack or extend to the rotor edges, it is time to replace them. I just replace my OE rotors each track season, particularly since they are so reasonably priced. I have been using the Hawk DTC-70 pads front and rear along with the OE rotors front and rear with very good success.
