Tips for Improving Your Car’s Aerodynamics

Most cars are designed with aerodynamics in mind, from the rounded front end to the sloped windshield and the flat floor. Without these features, your vehicle can suffer from aerodynamic instability, particularly at high speeds. This results in wind noise, excess drag, and less reliable downforce, which reduces traction and creates unsafe turning conditions. 

It is evident that quality aerodynamics are crucial for any car. Even if you drive a car that is built for speed and performance, you can still improve the aerodynamics of your car. There are many reasons you would want to improve your vehicle’s aerodynamics, including better fuel economy, improved car handling, and less noise, and a smoother ride. If you would love to improve your vehicle’s aerodynamics, here are effective ways to do it. 

  1. Add a spoiler to the rear of your vehicle

Purchasing a new spoiler is one of the most effective ways of improving your car’s aerodynamics. A spoiler is a piece of trim that you can add to the rear end of the trunk lid that diffuses the airflow passing your car, helping to minimize the turbulence at the rear of the vehicle. 

  1. Install a wing

A wing is a large accessory installed at the back end of the vehicle. It has the same profile like an airplane wing except that it’s installed upside down. Air passing over the wing creates a downward force, increasing traction, which allows for better braking and higher cornering speeds. 

  1. Install a front air dam

While most car owners install air dams for aesthetic purposes, front air dams help the aerodynamics of your car by redirecting air. Adding a front air dam adds more downward force and minimizes drag by minimizing the amount of air flowing under the car. 

  1. Install a rear diffuser

A rear diffuser is a shaped piece of trim that you can install underneath the back end of your vehicle. It helps to suck the vehicle onto the track helping to enhance grip, specifically aerodynamic grip. However, a rear diffuser can’t be installed in all cars, as some vehicles are shaped in a way that makes installing one impractical. 

  1. Rake the vehicle

The raking of a vehicle is the process of lowering the front end to get a minimal wedge shape underneath the car. Raking helps to create suction underneath the car, helping to improve grip, cornering, and speed. 

  1. Replace tires

You can improve your car’s aerodynamics by replacing wider tires with more narrower ones. Wide tires obstruct the air flowing underneath the car and increase drag, while narrow tires can help avoid this problem. 

  1. Rolled up windows

Rolling up your windows when travelling at high speeds is probably the easiest way to improve your car’s aerodynamics. Open windows allows vast air quantities to enter the interiors of your car creating unnecessary drag, which slows down the car.  


These are effective ways to improve the aerodynamics of your car. By taking these steps, you can improve your car’s fuel economy, minimize drag and improve your car’s handling.
