Hi again Ken, When I took the test (many years ago) to become a PA motor vehicle inspector, you could not have any visible cracks in either a drum or disc brake rotor. I'm sure many dealers understand that these cracks emanating from the holes in drilled rotors are not a problem. But as far as I know, the state does not differentiate on rotor type. Why not look for "plain jane" rotors for regular use and save the drilled ones for the track.

I agree with the slotted rotor preference.
Wally,
Thanks for the input. Also, thanks for helping with the VIR tech! Now, where to get cheap, slotted rotors, quick...
BTW, my son suggested that I check the actual state requirements, as he successfully argued with a shop re: failure due to some other issue which turned out to be NOT what the state actually requires. The state guide, Pub. No. 45 doesn't even address rotor cracks, only scoring greater than 0.015 inch. I will check with Eric Haas at POML, see if they would also feel compelled to fail the car. New rotors in 10 days would be a PIA, or expensive, or both!
