M3 side skirts don't fit the sedan as a simple snap it, the track that holds the snap in plastic pieces is lower/higher? than the sedans...lengthwise it looks like it'll fit, but it don't, I tried to get them installed on mine when I got the reiger front bumper installed. The body guy even tried to drill new holes along the line of the M3 track and when he tried to snap it in, the sideskirt itself was all wavey, not a smooth finish.
