My brake rotors have an indent about half way up the rotor surface all the way around. The replacement pictures from NAPA don't have the indent, and I'd really instead like to get mine turned to save some cash if I can.

Questions:

A) what is this indent for?
B) are these original rotors?
C) Can they be turned?
and finally D) does anyone have any pictures of original C20 rotors?

Thanks
