hey everyone i’m making this post mostly for reassurance, i drive a 15’ 428xi im doing msport bumper conversion, i showed photos of my current base rear bumper pdc and the aftermarket rear bumper. it had me put these inserts in. i believe the inner part is 18mm like my current bumper is but the hole was obviously larger before i put the inserts in. i just wanted to make sure i bought the correct bumper and that my current pdc sensors will fit correctly in the aftermarket one i bought online. do i have any worries?

FWIW, the rear PDCs on my M Sport rear bumper have inserts like that. I think you’ll be fine…

It is correct to have hole spacers for outside PDC sensors in 4 series M Sport rear bumper cover. As long as you put them in correct side - left or right with correct orientation pointing up or down. I believe spacer could have the UP orientation marked or have a shadow marked on inside surface of the bumper cover.
