A set of RW Carbon fiber side skirt extensions are a must have for anyone completing their CF build. A front lip and diffuser combo is never complete without a set and these GTX skirts are a great choice. They are more aggressive then some of our other choices, which go well with our larger and more aggressive diffuser and front lip options. We handcraft each set of F82 F83 M4 carbon fiber side skirt extensions with 2×2 weave 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, which are included with purchase. Get high quality and great fitting set of M4 carbon fiber side skirt extensions the first time, so order yours through RW Carbon. If you have any further questions please reach out to one of our CF experts.
