Funny thing my buddy noticed about his Z51 C6 is that he has the exact same "cross-drilled" rotor on both sides of his car, meaning that both the right and left rotor have the same part number. The problem is that they look to be directional fin-wise. He thought Chevy had put the wrong rotor on one side but he verifed with the parts department that indeed the right and left, even though they look to have directional fins, both are listed under the same part number.
