      Description

      Widebody Transformation. Tailored to 2018 - 2023 Ford Mustang Fastback models excluding GT350 and GT500 models, the Robot Body kits CMST Widebody Kit delivers a dramatic exterior overhaul with broader proportions, a more aggressive stance, and unmistakable motorsport-inspired character. Its combination of FRP and carbon components creates a comprehensive styling package that pairs bold visual impact with aerodynamic intent, while the recommended wheel specifications help define the planted look the kit is built to support. Because the surfaces arrive unpainted, builders also have the freedom to finish the kit in a way that complements the rest of the project.

      Construction and Appearance. This kit combines FRP and carbon construction to create a balanced mix of structural durability, reduced weight in key sections, and premium visual contrast across the full package. The FRP front bumper, widebody fenders, side skirts, and rear bumper provide the foundation for the widened profile, while the carbon lip, canards, lower side skirt sections, and diffuser add a more upscale performance-focused finish. Its unpainted surfaces are ideal for custom preparation and final coating, giving the installer flexibility while preserving the quality of the underlying materials. The aerodynamic finned and contoured shapes, together with the widebody proportions, give the package a distinctly high-end appearance that looks both purposeful and refined. From the panel layout to the material selection, the overall build emphasizes craftsmanship, durability, and show-ready styling.

      Installation. Installation follows a direct replacement approach, but because this is a full exterior conversion, careful mock-up, panel alignment, and hardware organization are important before final assembly begins. The adaptable design supports a staged installation process, allowing each major section to be positioned and checked for consistency before surface preparation and finishing work are completed. Reviewing wheel and tire clearance against the recommended sizing is also a smart step during the build so the final presentation remains balanced and functional. Once installed correctly, the kit integrates across your vehicle with a cohesive, dramatic result.

      Application. This Robot Body kits CMST Widebody Kit fits 2018 - 2023 Ford Mustang Fastback models and excludes GT350 and GT500 models. It enhances the vehicle with a substantially wider visual footprint, more aggressive body lines, and a custom appearance that stands apart from standard exterior styling. The included aero-focused components and full-body transformation also help create a more complete and premium performance presentation.
