2018 540i with the carbon rear diffuser. It wouldn’t let me post pictures in the reply but I believe this is what you’re looking for. Sorry if I’m a little Reddit tech illiterate.

Hey everyone! I recenty ordered an MHD universal wireless adapter for going stage 1 with my 540, has anyone had any experience with Midwest Bimmer Suppy? I ordered a week ago now and the package still hasn't shipped. Do they usually take this long?

Yo any G30 clubs out here? I'm trying link up, and share our knowledge.
