Confirmed!! The M5 front sway bar is a direct fit for my 2013 535xi!!
Visually it is much thicker and so far the car feels more planted and tight. Will report back after some more driving but so far its worth every penny!
This a big news for the F10 community lusting after better and sportier handling!
Next up...550GT rear sway bar after Joe confirms 100% it fits.
