Every F8X M3, M4, and M2 Competition could use a little spice in the cabin. These carbon fiber seat backs are the easiest install one can do. Even easier than buttons! Add some double sided tape, and slap them on! Fitment is just right! They have a high gloss 2x2 carbon fiber weave that'll match other components you already have. Each order will come with a set of (4). 2 front seats and 2 rear head rests. We recommend using ADDITIONAL double sided tape to ensure they are staying for the long run!
