For sale is a BBK for a bow e46 non M series. I had it installed in a 2004, 325i for a while. I no longer have the car and I keep the brakes in hope of getting another e46, well, that did not worked out and now I have no use for this. It comes with 4 piston front calipers and 2 piston rear. The disks are approximately 13 inches in diameter; I had 18 inch wheels on the car and it cleared the calipers, Im not sure if it will clear any other smaller sizes, Also have a set of hubcentric spacer, I had the wheels with the wrong onset and the calipers were rubbing in the wheels, so the reason for them. They come with two sets of brake pads and braided lines. Any questions, feel free to contact me.
