A buddy of mine had the same problem with his TMS slotted rotors that he ordered. The front rotors were identical, meaning that one of the slotted rotors faced forwards while the other was backwards. I've read up on this quite a bit and it's not really the face of the rotor that makes a difference (slots/drilled directions) but more the inside "veins of the discs that matter the most. They should be at a 45 degree angle BACKWARDS away from the front of the car to help with heat dissipation. So although it make look funky to have two front rotors that are the same, it all really depends on the veins of the rotor. So check the inside veins.

EDIT: This was also confirmed by the Brembo reps that I was talking to yesterday at the Big SoCal Euro meet.
