Does anyone have the breaking distances for the 50i with standard brakes and the M sport brakes?

A second question....
Better breaks seem like a great idea. I am having second thoughts about the "upgrade".
With so many autonomous controls which include braking, I am wondering if it is really good to upgrade the breaks? My sales associate says he can get the M brakes on the standard 50i (as opposed to the M sport version). I jumped at the opportunity, and now I am concerned that it might not have whatever tweaks in the software safety systems that might come with the M sport version, and become a problem instead of a benefit.
I believe the m sport brakes will require the 20" wheels as well. I chose to go with the 19" wheels because we have a lot of pot holes in New England and tire damage is too frequent. We just replaced a tire on my wife's seven series due to pothole damage to the sidewall.
Do you have any information or opinions on this?

The m sport version of the 50i is not an option for me because I want the off road package.
