Has anyone come to a conclusion why those parts have different numbers?
I am certain for sure that it cannot be because of a cover behind a fog light (M air duct in this place), because I have seen M bumper conversions and non M wheel wells front are p&p when you replace cover with air duct and also lower part which attaches to the M bumper itself.
Rear one left side is the same for all E85/E86 but right is unique only to M models, I guess because of dual exhaust and no battery box

Still, 225/45 is bigger in diameter by 22,5 mm than 225/40 meaning + approx 1,1 cm of higher tyre, how can you fit that in there if I cannot put my finger between tyre and wheel well front part (pic below). I have like 0,5 cm of space so how can Z4M accomodate 225/45 tyre turn wheels and do not rub?
Can you elaborate more?
There was also an idea in my mind that maybe it's been "streched" in horizontal dimension (front-rear) so that it can accomodate 225/45/18 instead of 225/40/18.
Pics for reference.
