Carbon fiber side skirt extensions are an absolute must have to complete your aero kit! These PSM Style BMW F8X M3/M4 side skirt extensions are our most modest looking and priced option. However, they are still made using our high quality materials and will pair great other less aggressive front lip and diffuser. If you need help deciding on which parts these will pair best with please give one of our carbon fiber experts a call. We hand craft each set of F8X M3/M4 carbon fiber side skirt extensions with 3k 2×2 carbon fiber and complete them with UV resistant clear coat to ensure they do not fade or discolor. Installation can be completed by any enthusiast and just requires self-tapping screws.
