Does not sit flush with my diffuser, id be sending them straight back if I hadn’t tried putting a self tapper into my back bumper to solve the problem getting it flush, waste of money.

Sorry to hear this. Can you confirm that you've got the ZAERO diffuser installed too?
Have you got any photos of the poor fitment so we can resolve?
Thanks

Fitment was excellent on my F20 LCI 120i, the installation was a breeze on OEM mounting and the finishing is what you would expect from AUTOID and ZAERO 10/10. Very responsive Facebook customer service that provided me with a hassle-free shopping experience.

BMW M135i & M140i F20 F21 LCI EVO-1 Gloss Black Diffuser Side Spat Flap Extensions by ZAERO (2015-2019)
The Zaero Design Diffuser Extensions (Left & Right Side) for the BMW 1 Series M140i (LCI) are easy to assemble in just a few minutes. They fit directly onto the OEM mounting points, NO extra drilling, glue, tape or fixing is required. Just bolt on and ready to go!
The Diffuser Extensions give the rear of the BMW 1-Series in combination with their EVO-1 Diffuser a deeper and more distinctive look and combine the lines of the Side Skirt Extensions with the Diffuser Extensions. They're just a small upgrade but make a big affect to the rear of the car.
