Hello all

My 220d used to have standard small brakes. I upgraded the calipers with M-Sport brembo ones. With 340-345mm Zimmermann rotors, ATE pads, Goodridge brake lines and Motul RBF700 fluid.

I have no problem in track and daily. I am driving my car around 25.000km per year with 5-6 track days.

Only thing is, brake pedal bites a bit far, but i guess all bmws are like that.

Should i upgrade the brake servo unit with M-Sport's?

I found a used M4 brake servo unit, can i use it without problems and will it be better?

Is using standard servo dangerous for me in track?

I would like to hear some experiences, thanks
