I am not so sure about the other posts and their level of concern regarding BMW engineers have calibrated parts and suspension for a 19 and 20 set up only.
Consider BMW M themselves have made a 20 and 21 wheel combo to be fitted to the G platform. They call it the ‘M performance wheel’.
Therfore if BMW M performance team have made a 20 and 21 wheel, that contradicts the statement that BMW engineers have designed the car for 19 and 20 only so any alterations from that will me detrimental.
Furthermore , BMW themeselges have called this 20 and 21 wheel set for sale as their “M performance parts” therfore indicating that not only does it NOT hinder functionality, they are advertising it IMPROVES PERFORMANCE.
