Description

The Vega Motorsports FOCUS ST DIFFUSER (V1) is a rear diffuser meticulously crafted from high-end medical-grade aluminum alloy. This material choice ensures the diffuser is not only lightweight and durable but also corrosion-resistant and 100% recyclable. Designed using professional CAD software and cut with precision via an industrial CNC machine, the diffuser is powder-coated in-house. This V1 diffuser is designed to fit the 2013-2018 Ford Focus ST models equipped with the factory rear bumper. It features a choice of two fin styles, STYLE 1 or STYLE 2, and includes all necessary mounting brackets and stainless steel hardware for installation. The product page notes that drilling is required for installation, and provides an online installation guide. Buyers can choose between a raw, unpainted finish or a satin black powder coat. It is important to note that ordering the raw (unpainted) option will require the client to perform sanding and coating themselves, and raw aluminum pieces may arrive with minor stains or scratches. Due to the custom, made-to-order nature of these diffusers, no refunds are offered. Professional installation is highly recommended.
