Track-Inspired Aero for the Ultimate Shelby Stance. Sharpen your rear-end styling and improve high-speed stability with this Rear Diffuser Strake Kit, custom-tailored for the 2015–2020 Mustang GT350. Designed to integrate seamlessly with your factory rear diffuser, these strakes add functional downforce management while giving your Shelby a more aggressive, motorsport-inspired look.

Optimized Airflow and Rear-End Control. By channeling underbody airflow more precisely, the strakes reduce turbulence and rear-end lift, helping to maintain planted stability at speed. Whether you're canyon carving or pushing through fast sweepers at the track, this Rear Diffuser Strake Kit adds real aerodynamic benefit without compromising ground clearance or daily drivability.

High-Strength Construction, Built for Speed. Crafted from durable ABS plastic, carbon-reinforced composites, or powder-coated aluminum (varies by brand), the strakes in this Rear Diffuser Strake Kit are engineered to handle the harsh conditions of track and street. Their robust build quality ensures they won’t warp, crack, or fade, even after extended exposure to road debris and UV rays.

Installation. Putting this Rear Diffuser Strake Kit on your Mustang GT350 takes 1 hour to install.
