From the CSG FB page:

I use my fingernails to quickly determine if the fractures are wide enough that the rotor needs to be thrown away. If a fingernail catches on a fracture, the rotor is done; if it slides over the fracture, the rotor is still good. On the AP Racing Competition Kit on my car, it takes awhile before the fractures open up to the point shown in the rotor on the right.

That is a lot of tire for a ~170 RWHP car - you may find it useful to get a probe pyrometer and learn to use it. That will help you find out if you're heating your tires up to their optimum operating range. You can also use the temperatures you record to fine-tune your camber and toe settings.
