What is the minimum and starting thickness of the stock rotors (performance model)?

I cannot find anywhere the minimum rotor thickness before the stock rotors are deemed unsafe. If someone else has this snippet of knowledge, please do share. Thanks!

The min thickness is usually stamped somewhere on the outer edge around the outside perimeter of the rotor, or around the hat area.

I found the markings. They are located in the vents on the rotor. Kind of a PITA to look for.

Anyways, the etchings indicate 30mm front min thickness and 18mm rear min thickness.
