It is pretty common, my lotus elise had the same thing, one rotor seemed correct the other was identical and backwards. It had no neg.effect, the z51s are the same, the 08 piece look good, the 08 z51 have larger cooling vents ducts in front and rear vents with plastic vents blowing on the rotors. The front rotors look beefie, if they crack they are cheap enough, will hold out for two piece units and get the most out of these.
