Description
This item does not fit 991.2
Enhance the aerodynamic efficiency and aggressive styling of your Porsche 991.1 GT3 with the APR Performance Carbon Fiber Rear Diffuser. Designed to work in harmony with your vehicle’s aerodynamic system, this high-performance diffuser improves airflow management, reduces turbulence, and increases overall downforce for superior high-speed stability.
As your vehicle moves forward, air disruption at the rear creates a low-pressure vacuum. The APR rear diffuser is engineered to channel high-velocity airflow from underneath the car and smoothly transition it into this low-pressure zone. This process reduces drag, enhances aerodynamic efficiency, and allows other aero components—such as wings and splitters—to perform more effectively.
Constructed using advanced pre-preg carbon fiber technology, this diffuser delivers exceptional strength while maintaining a lightweight profile. The result is a race-proven component that improves both performance and aesthetics.
