I want to switch my rear bumper on my base 2019 bmw 540i because the one right now is a one piece, meaning I can’t put a rear diffuser(it’s non msport, but luxury line). I’m trying to find a rear msport bumper that can fit my car and one that allows me to put on a rear diffuser. Anyone have any good sites to find one for a relatively reasonable price?
