Upgrade your interior with the BMW G8X M3/M4 Carbon Fiber Side Seat Trims. These trims are made using authentic 2×2 weave carbon fiber, finished in a high-gloss clear coat, and add a clean carbon accent to your seat bases that pair well with any other carbon interior parts you may have. Our seat trims are designed to fit directly over the existing factory piece using 3M tape, so no special modifications are required. Please note that these do not fit carbon bucket seats.
