Still measures 31.5 mm, and I am told I don't need new until 30. But look at those grooves!

Cracks in the interior areas of the rotor are fine as long as you can't stick a fingernail into them.

What should I do? Can I get a rotor for the Stoptechs from anyone but Stoptech?

ATE, Zimmerman, Brembo, Alcon, PFCs and StopTech have all exibited cracks like that after track/race use. The Porsches and BMW's we service also exhibit cracks if the cars are driven hard....normal for rotors to do that. If the cracks extend to the outer or inner edges and you can put your fingernail in them....they should then be replaced.

If you track your car at all, this is normal.
