I wanted a diffuser for the longest time. Nearly all are carbon fiber, which I don't care for, and worse yet will block the " kick to open" comfort access that I use nearly every day. I didn't want to lose that.

I had thought of this exact idea a year ago. The existing options out there for fins look terrible and cheap. The profile wouldn't match our cars at all. Abandoned the idea.

I finally decided to give in and sacrifice the comfort access for the way better looks of the OEM M performance diffuser insert. I was literally about to pull the trigger and saw this thread.

Is the mounting hardware from the inside? If it isn't it wouldn't be a bad thing. All would be hidden externally. Even if it means removing the insert for installation.

Thank you sir. Add me to the list. Exactly what I was looking for. 3 fins and it's gonna look great!
