How long have you had these pads on when you wrote that write up? That's so weird. I had Ultimates on my e34 and they were amazing. And now I have them on my M3 and they are still performing great. In all honesty I think you either got some sort of defective product or there is already soemthign wrong with your brakign system possibly amplified by the fact that it took you so long to correct your warped rotor.
