Are you all going genuine M-Performance parts or are you going IND, e-bay, Alibaba and the likes ? |

Did this today and here's my take...
What a ROYAL P I T A!!! Bolts and push pins were nothing, obviously. The ends of the stock diffuser came out fairly easily. I tried the pry tool method on the middle tabs with little success. It came down to wiggling and muscling the OEM unit out. I'm not a dandy, but my hands sure paid the price. And, I feel certain there was some minor damage to the female lip of the bumper where the tabs go. The M Performance C/F diffuser (thanks SunMotorsBMW) went in without a hitch - except for one tab. Had to reach my arm around and over the exhaust to push from the back side. WE HAVE ENGAGEMENT!! In the end, the new unit fits perfectly and looks great. Glad I tackled the job and always enjoy the challenge of doing things myself. Good Luck!! |

Yep, definitely a hard job. I think it's important to note the where the notches are on the tabs. I filed down a couple carbon tabs to make them go in more easily.

You're a better man than me, that's all I can say. 10 mins was all it took me but not without causing catastrophic damage to the stock diffuser and my hands.

The key is to place one hand on the bumper and then do a very quick sharp yank motion directly towards you on the stock diffuser at the tab areas - that will pop the tabs out safely - no need for pry tools or anything
Slowly pulling and prying flexes the plastic / urathane and causes cracks / tears the stock parts although at the surface seems like the safer way to do it by going slow - it’s more likely to cause damage 🤙🏻 Last edited by eatingpizzainthef87rules; 10-10-2018 at 10:18 AM.. |

Theres a place local to me that allows me to rent out a hydraulic car lift for only $15 an hour, wondering if it's worth it to do that while I install the Diffuser, Side Skirt, and Front splitter. Do you think it's worth doing that to make it a bit easier or should it be easy enough with just a car ramp I purchase from walmart? Also I'm assuming this is similar instructions to what I'll need to do on my M2 Competition? |

Of course it takes 5 more minutes for opening that shield but working from the inside gave me the security I was looking for. I didn't want/dare pulling blindly on the stock diffuser and ending up with a broken tab or a damaged diffuser. By doing that it took me 15 minutes all together but without any brute force. Just gentle traction while pulling down the tabs from the inside with a screw driver. |

I wouldn’t worry about it. I threw my OEM diffuse away. Not much in the way of resale of the OEM product.

I put mine on last night and I didn’t think it was to bad. I used plastic trim removal tools to release the clips which made t a lot easier.

Just finished installing. Oddly enough, not much of a problem removing, just took a bit of force. Installing was a bit more difficult as the driver side really didn’t want to go in. Eventually got it though.
Found the 2 extra pieces that fell out after I pulled the stock diffuser out. Any idea what those are for? Like everyone, left them out. Assuming this is fine. |

Try to install the BMW CF diffuser on my M2C, the tabs wont go in no matter what angle I tried... Spent 2 hours still cant them push in... Should I ask my dealer to install it? Any other tips?

Fitted tonight. About 20 mins, the centre studs are a little tough but worked outsides in and it wasn’t so tough. Juts a tug as close to each one as possible. New one went on very easily, but you do need to give it a firm push, again working outside ones in. Well happy with the results!
