A rear bumper diffuser allows air to pass more quickly and smoothly in the lower part of your vehicle, increasing the car’s grip on the surface, reducing drag, and making the vehicle faster and more stable. Our Ford Mustang rear diffusers offer the highest-quality construction for stability and durability. They’re built to withstand harsh conditions, which gives them good high-temperature resistance to maintain an excellent condition for a very long time.
