Part# 31356791924 is what comes on a standard 535i here in the US. When i plugged in that number in that website it lists a bunch of cars that also uses the same part and your 528i is included. This means since the M5 bar fits a 535i, it will also fit a 528i.
So the M5 1 should fit the M Sport too, right?
