I was installing these yesterday on my ‘18 M3LR and noticed a fatal flaw in the design. The middle two screws and passenger side bolt rub against the hoses it’s trying to protect. I added photos of one screw and a bolt, although I didn’t insert the bolt completely in the photo. The two middle screws have about an inch before they’d make contact with anything. Let me know if this seems worthy of its own post to warn other owners.
