Show original supplier description
The MMD by FOOSE Rear Valance Diffuser offers a distinctive, aggressive race-inspired styling upgrade for your 2013-2014 Ford Mustang GT or V6. Designed in collaboration with renowned custom car builder Chip Foose, this rear valance utilizes original Ford CAD data to ensure a precise fit and a seamless integration with your Mustang's existing lines. Constructed from high-impact, thermo-formed ABS plastic, this diffuser is both durable and lightweight. It features a factory-style grained texture, providing an OEM appearance while also offering increased resistance to damage from road debris. The diffuser attaches to the factory rear bumper cover using supplied push-pin retainers and 3M automotive bonding tape. The process is estimated to take approximately 2 hours and requires light to moderate mechanical skill. This MMD by FOOSE Rear Valance Diffuser is specifically designed to fit 2013-2014 GT and V6 Mustang models equipped with the stock rear bumper. It is explicitly stated that this product does not fit Shelby GT500 models, nor will it fit with GT500-style rear bumpers.
