Ford Mustang S197 APR GTR Carbon Fiber Rear Diffuser 2005-2009

Enhance the rear aerodynamics and performance styling of your Ford Mustang S197 (2005–2009) with the APR Performance GTR Carbon Fiber Rear Diffuser. This race-inspired aerodynamic component works in conjunction with other aero upgrades—such as splitters and wings—to generate rear downforce, stabilize airflow, and reduce drag for improved high-speed handling.

As air passes beneath the car, the diffuser channels the high-speed airflow toward the rear, allowing it to transition smoothly into the low-pressure zone behind the vehicle. This effect reduces turbulence and lift, creating a more balanced and stable platform during acceleration and cornering.

Constructed from aerospace-grade pre-preg carbon fiber and autoclave-cured for maximum strength and low weight, this diffuser offers both functionality and premium appearance. Each piece is finished with a UV-resistant gloss clear coat to protect against fading while highlighting the deep carbon fiber weave.

Note: This diffuser is available for both standard and widebody rear bumpers. Please select the correct configuration for your vehicle before ordering.
