M Performance Brake Kit Upgrade

I recently replaced the stock rotors and calipers on my 2016 228i xdrive with M Performance brakes. While they work well, I encountered a problem with the inner diameter of the rotors being larger than stock. Consequently, my e-brake shoes lack sufficient grip on the inner diameter.

After researching, I found that there are two sizes of brake shoes (165 and 185). I'm wondering if there's an adapter ring available to compensate for the difference in size? Swapping to larger shoes might not be feasible due to fitment issues with the current wheel knuckle.

As far as I know, you're going to have to buy the correct rotor size, sorry. I know its a little confusing if you're looking at the pdf installation instructions from bmw since all they say is rears not included, make sure you get either this one or that one without specifying so I get it.
