Put those on my 335 and 525. Fucking hate them. Not sure if it's the ceramic pads or the lack of friction surface area of a slotted and drilled rotor. But they have no bite. They always feel faded.
It's hard with BMW bc the OEM brakes have do much bite.
I think pads make more of a difference them rotors. Get textar pads as they are the un branded OEM. And just any OE rotor. Zimmerman are ok but their coating is a gimmick. It wares off immediately
