Looks good
Fit well on a 2018 f30 340 x drive msport. It is carbon fiber, not plastic. Was packet well and had no damage or scratches. Looks great on the car. Much less expensive than other "brands". 7 screws and some wiggling and it's installed.

Fits but requires adjustments
This CF rear diffuser definitely adds definition to my MPPSK carbon fiber tips. I also added carbon fiber overlays to my rear reflectors. I had to drill the side holes on either side a bit larger so the clips could fit, which created a bit of debris, and required some finagling so the OEM screws could align. The tabs don't actually secure the diffuser into the slots for the same snug fit as the OEM, which is unfortunate. It does appear to be real carbon fiber weaves when I examined it deeply. Only time and environmental exposure will test the long term quality.

Quick and easy to install
The diffuser fit my F30 with M sport body kit really well and snaps into place easily along with securing with OEM screws. May require heating and or strong double sided tape to have a more flush fit towards the far ends as it kinda flares out without.
