Remember when I called the BMW M4 one of the most tuner-friendly cars in the market today? While that’s still true, there’s also an alternative truth to it and that alternative truth is this: the BMW M4 may no longer be the favorite BMW M model among aftermarket tuners. A case can be made that the M2, the M4’s younger brother, has that distinction. It’s hard to argue against that assertion because the M2 presents a strong and compelling case. Unlike the M4, the M2 has only been around for a little over a year and yet, there are already a good number of tuners that have developed and unveiled programs for the small performance coupe.
