Why the Porsche Cayman GT4 uses golf ball dimples to cut through air

While the Porsche Cayman GTS 4.0 focuses on minimizing lift, the GT4 is engineered for maximum downforce. This video explores the specific aerodynamic modifications, including a dimpled underside, that allow the GT4 to reduce drag.

The GT4 features an upgraded chassis, suspension, and engine tune compared to the GTS 4.0. A key innovation is the dimpled surface on the car's front underside. Much like a golf ball, these dimples create a turbulent boundary layer of swirling air. This turbulence helps the airflow stay attached to the car's contours for longer, resulting in a smaller wake and reduced drag.
