Below are examples for 2019 F36 (manufacture date mid 2019) as an example.
Front Sport Line bumper set-up:

The M Bumper set-up for same car:

Look for difference in airducts as well. Some are interchangeable between SportLine and M Type:

Good luck.

Nothing is interchangeable between the sportline front bumper and the m sport front bumper except for the kidney grills and the reflectors. All the ducting, supports and almost everything behind the bumper changes when you go OEM. It's not an easy swap and it's expensive. But, nothing beats OEM for body parts imo.
