I'm going to try and install them on my Msport, which should be here any day.
I asked for a set as part of the deal.
Some say they won't fit an Msport, but most of the different body work is in front, and the area where the flaps go looks to be the same.
On my 135i they also said that the front flaps wouldn't fit due to the different front of th 135i vs the 128i, but they fit just fine.
I'll post a pict if they do fit on an Msport.
