If you require a carbon fiber extension for your M3 that is more aggressive than a simple blade then our GTX side skirts are what you have been looking for. These F80 M3 carbon fiber side skirts contours the rocker panel and protrude about 2.5″ giving your car a lower appearance, even if you are still at stock height. We hand craft each set from genuine 2×2 carbon fiber that will nicely match any other RW Carbon parts you have on your car. To make them impervious to dirt and debris we finish each set with a UV resistant clearcoat which will ensures they stay looking great for years to come. Installation is completed with self tapping screws, which are included with each purchase.
