Better Stability: Improved airflow reduces turbulence at the rear of the vehicle, allowing for a more stable ride. This is especially beneficial during high-speed maneuvers or performance driving.
-
Enhanced Cooling: A well-designed rear diffuser can also help in directing airflow toward critical components like the brakes or exhaust system, aiding in temperature management.
