Look at reamoem.com and start comparing part numbers. If your car shares any part numbers as the 535/550 when the M5 front bar will fit your car too.
Looking at the 528i it shares the same front sway bar as my 535 if you have the ddc/edc shocks so safe to assume the M5 bar will fit. No gurantees though but I'm willing to bet it does.
