They're not engraved, its literally just stenciled. I'm comparing it to a Toyota caliper, because without the stenciling, with or without the red paint, it looks like any ordinary OEM caliper, especially because I'm gonna be going with plain 15" rotors. No drilling or slotting.
EDIT: And If I decide to get some other than standard brake pads like EBC Yellowstuff, It will be way harder on the calipers and rotors. The amount of dust and heat they kick off is crazy. Just something to think about. I know running non-standard pads on the Brembos or Wilwoods isn't something you generally do, but pad selection is going to be an easier thing with the z06s. Not that its really 'hard' for the BBCs, because you just call and crossrefrence the part number from the BBC maker, but it is easier for the z06s.
