The Anderson Composites carbon fiber rear diffuser for 2015–2020 Ford Mustang Shelby GT350 and GT350R is a hand-crafted replacement intended to swap in for the OE rear diffuser. Made using 3K, 2x2 twill weave carbon fiber and a proprietary vacuum infusion process, it delivers a high-gloss, wet-look finish. Note: this diffuser replaces the Shelby OE unit and will not fit standard Mustang models.
