I believe that ATE is the OEM supplier for brake rotors. I have a set of Brembos on the front that I believe warped not too long after putting them on. (I've had a light steering wheel wobble that is either a bad control arm or bad rotor(s)) I have a set of the ATEs on the rear and seem to be nice.

The ATEs boxes are marked with "made in Germany", so I'd trust them more than the Brembos. They are only a few dollars more than the Brembos anyways.
