This set is amazing. Fitment was no different than OEM, everything fitted perfectly, 2000 328i. As to be expected with this type of rotor, they are louder than the original, you hear them "buzz" as you slow down. It's worth it, once you break them in (just drive like a normal person for the first few hundred miles) those brakes will stop. Excellent pedal feel, no brake sag under hard riding. And they look great. Take some time to clean and repaint the calipers to get them working.
