Mein Auto: M3/X3/XI
I don't have this specific kit, but I do have these rotors installed on our X3 along with EBC brake pads front and rear. I think you will immediately notice the increased noise level. Under heavy braking, these rotors (due to the slots) make a heavy "groaning" sound. You'll see what I mean after you install them. My M3 has the European CSL brakes which are cross-drilled from the factory and they make considerably less noise since they are not slotted. I previously has cross-drilled/slotted rotors on the M3 and they were quite loud. Its a small sacrifice for me (possibly larger for others) to get increased braking power and reduced brake fade.
BMWs currently in the garage: VF570 E46 M3, E46 XI Touring, E83 X3 "M" retrofit
