Advice RE installation of M-Performance Rear Diffuser on M340i
Hi all,
Took delivery of an M340i just two days ago and its currently with the detailer to do a bunch of things, including installation of M-performance bumper trim and gloss black rear diffuser. We're unsure of whether we're supposed to "break" some tabs off the end of the rear diffuser? Anyone install this combo before and know what to do? Some pics for reference below, including the relevant parts from the official BMW installation documentation. Thanking you kindly in advance. |

Responding to my own thread if it helps anyone else in future - pretty confident after more consultation/reading that the tabs are supposed to be broken off as this part has different holes to work for 330i and m340i.

I installed the m performance gloss back diffuser and m performance cf insert on my m340i. No tabs should break when removing the oem diffuser. There are a number of good how tos online. That's what I followed.
