The MHC+ GTX Side Skirts for the BMW F80 M3 and F82/F83 M4 form the central element of the GTX system, designed to visually lower the car and create a strong, uninterrupted horizontal line that ties the front splitter and rear diffuser together. Rather than overcomplicating the profile with surface noise, the GTX skirts are intentionally clean — allowing the carbon weave and the car's factory proportions to do the talking.
Each skirt is manufactured from 100% pre-preg carbon fibre, finished in a deep high-gloss lacquer with an OEM-style weave that complements the rest of the GTX kit and the wider MHC+ catalogue. Designed in CAD from a full 3D scan of the F8X chassis and validated with 3D-printed test fitments before tooling, the skirts integrate flush with the factory rocker panels for an OEM-grade fit.
For the focused F8X enthusiast, the GTX skirts deliver an aggressive, purposeful presence without entering an ultra-premium price bracket. Supplied with all required mounting hardware and pre-applied adhesive tape where necessary, and backed by MHC LDN's fitment guarantee and comprehensive 3-year warranty.
