My point was coated wheels would dust less (or show less dust). Still one possible factor.
I agree drilled rotors will dust more.
Was a good observation... just too many variables to assess if there is anything different about the M2 brake pads... especially if the M3/M4 with the same brakes was not as heavy on the dust.
Once I get my car out of hibernation, I will be able to see really quickly if it is as bad as my old 135i for dust.
