Years ago, the ATE rotors were made in about every other country EXCEPT Germany, as you know, no one makes rotors for BMW, except Brembo, who makes them for the 840i ONLY. ATE is an OEM supplier for hydraulics to BMW, but NOT rotors. most of the ate rotors that were warp city were made in Italy, and we had HUGE problems with them. The latest rotors from ATE(within the last year) that are gas slotted are made in Germany, I bet that if you checked the rotors you had warp problems with, you would find that they are made in another country. Also, stock rotors are made for street use, I doubt a street rotor will take the harsh life of track use, those who expect the car to not break on the track are in for a dissappointment.
