Just did mine. Put the back of the car on ramps to make the job easier. Done in 30 minutes. The center tabs are a pain but come out. I thought I was going to fall backwards when the first center tab released. New diffuser popped right in with a slight pound with my hand over each tab. Mine also has that slight extra space on the driver side if you know it's there. For CF, the BMW part fits 9.8 out 10. I think a little 3M tape will help the driver side if needed. I do not think the tabs on carbon fiber will survive removal if you want to sell this part later on.

Yup went to the dealer today for 2 hours couldn't get the diffuser to fit. The tabs are too thick. Ordering another one probably will take another month or two.

You have to pound it in. They don't know what their doing. 2nd one will be the same.

I agree it's install error most likely. I had TWO diffusers, EAS installed them both and actually fucked my bumper up so the tabs will always be visible unfortunately...

Just received this part and wanted to bump this thread in case anyone has any new tips on how to make the install easier. It's a popular piece so I'm wondering if most people have the dealer install it or try to do it themselves.
Thanks for the write up, btw. |

When installing I just banged it in with the back of my fist, I had a problem getting one of the pop rivets back in the drivers side but just left it till I get it on a lift. The rest went in fine, fits perfect. |

Great info BSMF87. Thanks!
After reading the trouble people had in this thread with installation I ended up getting in touch with Andrew@SupremePower. They had experience installing this piece and made quick, easy work of it. I think total time was something like 15-20 minutes, and it looks great! |

Tabs are too thick? Pretty simple, make them thinner. I had the same issue. I used an exact knife and very carefully shaved down a couple of the tabs. Really a challenge to use the same installation with carbon as with plastic - the carbon has no flex and will not "snap" into the bumper. I also expect it will be more challenging to remove. With the plastic one, you can just forcefully pull it off.

Followed everyone's advice and started from each end before working towards the middle. Unscrewing the heat shield and sliding your hand up to the tabs made it easier. Last, I was able to get all the middle tabs out in only a couple minutes once I figured out the following. The tabs are held in place by the notch on top (duh) and the bumper has a second tab that keep the diffuser tab engaged. From the inside, I put a screwdriver between the bottom bumper tab, had someone then push on the diffuser releasing tension on the diffuser tab, and used my finger to squeeze down on the black diffuser tab and it slid right out. It was too cramped and dark to take a pic, but here is a diagram of what I did. Hope this helps others!

Today I installed my new diffuser and had a lot of trouble, even when removing the four extra screws under the car to access the underside of the diffuser.
After all that, I decided to try using my pry tool in order to get the tabs disengage. To my surprise, they popped out one by one, very easily. What I did was get the pry tool directly above the tab and apply downward pressure, then pull the diffuser towards me with my other hand. Once I figured this out, I was able to remove the diffuser within minutes. If I had known this from the start, I think this could have been a 10-15 minute job. Removing the extra screws underneath is unnecessary. Last edited by eeyang92; 10-13-2017 at 08:28 PM.. |

Think I was one of the luckier ones, 10 min job to swap! My stock diffuser popped out without the use of a pry tool, simply popped the sides off first, and then rocked the middle tabs back and forth from the ends of the diffuser and they just came out.
I actually bought my mp diffuser a month ago and was just putting off the install based on the horror stories I've read. Super satisfied with the piece though, really changes the rear of the m2 for the better! |

Hey All,
I have the M performance rear diffuser port installed, so I dont have the OEM diffuser lying around. I want to buy and reinstall the OEM diffuser. My question is do I need to buy the OEM clips and bolts or can I use the clip and bolts thats already on my M performance diffuser? Any info would be appreciated. Thanks |

OK. I just did it. My advice is: pull hard! and do not be afraid.
It took me (I did time it) 22 minutes from start to finish, not a second more. As you pull on the diffuser, the bumper will bend, but I was never afraid it was going to break, and I did not pull “as hard as I could” and I did not “almost fall backwards”. You just pull, and it comes out. That’s it. No worride to break anything. The bump bends as you pull, but that is what it is supposed to to: flex and bend. The CF diffuser snapped right in, and I could not be happier! Why pro installers have a hard time doing this? I cannot understand (at least the removing part, installing the new diffuser might be harder depending on the one you bought...) |
