There are many ways that you can enhance your car’s performance, but usually, if you’ve already gone through the basics of lightening it, giving it more power, better suspension, and better brakes, there isn’t a whole lot you can do easily after that. Except for the fact that there is, in the form of aerodynamic enhancements and modifications that can have quite a dramatic effect when done well.

You can gain the knowledge needed to do your own aero from this dedicated book called “Modifying the Aerodynamics of Your Road Car” by Julian Edgar.

According to the author, this book teaches readers how to visualize airflow patterns over the car, spot areas that could be improved, you can even “learn how to measure aerodynamic pressures, so you can determine which body surfaces are creating lift, drag, and downforce.”

Lowering cooling system drag, fine-tuning your car’s ride height, rake, and even how wheel designs affect airflow are also covered. So, in essence, the book teaches you how to attack the problem of improving the aero efficiency of a car by attacking the problem from several angles - some require more knowledge and are aimed at pros, but the basics are also covered.
