Description

This construction method ensures a consistent weave pattern, high stiffness, and exceptional strength. The component is finished with a marine-grade gel coat and UV inhibitors, polished to a high luster to protect the surface. This spoiler features an adjustable carbon fiber wicker bill with two positions, allowing you to choose the desired level of downforce. It is designed to utilize the OE Mustang GT wing mounting hole pattern, requiring 7 holes for installation. The package includes stainless steel nuts and washers, as well as adhesive-backed foam. Recommended installation involves adding OEM-style 2-sided tape under the spoiler, which is not included. This spoiler is specifically designed for 2-door coupe Ford Mustang models from 2015-2023, including Ecoboost and GT trims. It is important to note that this spoiler does not fit convertible Mustang models. Professional installation is recommended, as minor adjustments may be necessary during the normal installation process.
