In the conclusion to our month long look at the aerodynamic elements of modern day road and race cars, we will be looking at some of the accompanying elements that help the main aero devices do their jobs. If you haven’t read about these devices, you can take a look at the last three articles in this series: Part 1: the front splitter, Part 2: the rear wing, and Part 3: the rear diffuser. These three devices all work in harmony to achieve the maximum possible downforce with the least amount of drag. Sometimes, however, these elements need help directing air over them in the most efficient way. (continue reading…)
