-1. More pistons does not by definition equal better brakes. I'd be willing to bet the 135i does not have composite (two metals) floating rotors. These are key in resting warping. The M3 has a greater swept brake area per ton. The pad compound is another key factor along with designing for brake cooling by airflow. I am not saying the 135i multi-pots are bad but I have heard they fade as well.
