Description

The Anderson Composites AC-RL15MU350 rear diffuser is crafted from VIP carbon fiber for the 2015-2020 Ford Mustang Shelby GT350 and GT350R models. This aerodynamic enhancement is manufactured using a meticulous process where resin is applied to a mold, followed by layers of carbon fiber fabric, and then sealed in a vacuum bag for optimal curing and a superior fabric-to-resin ratio. The finished part is trimmed and polished with a protective gel coat, offering a high-luster finish without the need for additional clear coating. It is important to note that this part will not fit standard Mustang models. While designed as a direct fit for the GT350 and GT350R, mounting tabs may require modifications, and minor adjustments might be necessary during installation to ensure correct fitment. The rear bumper will need to be removed for proper installation.
