Description
Built for underbody airflow control and high-speed stability.
This is where the aero system starts working underneath the car. The diffuser manages airflow exiting the rear, reducing turbulence and improving overall stability as speed builds.
On track, the effect is subtle but important — the car feels more settled, especially in high-speed sections where clean airflow makes a difference. It’s not about adding grip in isolation, but improving how the entire aero package works together.
Platform
Porsche 987 Cayman
Notes
