Ok so I know that you need a bracket for the front brakes which I have but what about the rear? I know the rotors from an M4 match our 370x24 mm rear rotor but what about using the M5 rear caliper because I want to keep the e brake option working, I heard someone did it but dont think they used an M4 rear rotor with the M5 rear caliper, so i assume that the f10 m5 rotor and caliper will fit, what about offset ?
Thanks in advance!
