I'm considering a few simple aesthetic mods for my F31. I started looking through the BMW parts catalog and came across the "M Performance Side Stripes Kit". It's a black and silver vinyl strip that runs along the belt line of car. It's simple enough to install and removal should be just as easy if I don't like it.
I'm also considering the M Performance Side skirt decal. Though that may give the car an unbalanced appearance without the black front splitter in place.
Both vinyl stripe kits can be seen on the car in the photo below:
