Thanks for the update. Good info.
A question, what will the M brakes do for stopping distance? Also I have seen published articles saying the stopping distances of the F30 328i from 60-0 mph varying from 107 to 117 feet. The first is very good and the latter average. Can anyone give me better information. If the M brakes only give me better performance on the track with less fading I am not sure I need it. I drive conners quickly but do it smoothly without using heavy braking. Still I appreciated the ability to stop in the minimum amount of distance. I have Bremco brakes on my Volvo V70 R and I like them.
