LOL...stop causing trouble...
If it rusts...it's not ceramic.
If you don't see ceramic fibers...it's not ceramic.
If you don't have yellow calipers...it's not ceramic.
If digits 7, 8, and 9 of the parts number stamped on the rotor don't have 031 or 032...it's not ceramic.
If your dealer isn't going to charge you $7K to replace it...it's not ceramic...wait...they will charge that for a steel rotor at some dealerships. Forget I said that.

The Ceramic "hat" has a "SGL" inscription on it. Bob, your time to shine (again), who is SGL?
And one more, put a refrigerator magnet next to it, neither PCCB disc (carbon composite) or hat (aluminum) will stick.

Ceramic rotors are dark grayish, steel rotors should be bright.
SGL Group manufactures the rotors.
What is the diff between .31 & .32?
Thanks.

if a magnet sticks to the rotor...it's not ceramic.
