A rear spoiler is an automotive aerodynamic device whose intended design function is to 'spoil' unfavorable air movement across a body of a vehicle in motion. Spoilers on the front of a vehicle are often called air dams, because in addition to directing air flow they also reduce the amount of air flowing underneath the vehicle which reduces aerodynamic lift.


Rear spoilers are more common that front spoilers. A rear car spoiler gives your vehicle a beefy, sleek look. It makes it stand out in the crowd and can even increase the resale value of your car. However, the spoiler is attached not merely for its looks, though many people are not aware of this.
At first, rear spoilers were attached to sports cars and racing cars only because of their special utility. Good spoilers can help racing cars accelerate and brake at will, turn smoothly and ride comfortably. However, these days, you find spoilers in passenger cars too.


A  rear spoiler is a great aerodynamic addition to your gig. A spoiler is so called because it ‘spoils’ the flow of air around the body of your car reducing lift and increasing drag. Or, you could say that the function of a spoiler is to reduce the tendency of the car to lift off the road when it is in motion. The spoiler is designed in such a manner as to provide a downforce to the car when in motion. This gives your car greater stability, better maneuverability and great traction. A rear car spoiler increases the contact between the road and tire, thus increasing safety and grip. Some rear spoilers even have break lights beading them. So, every time you apply the break, your rear spoilers will light up, alerting the driver behind you. Thus, these spoilers are a safety device too.



The spoiler is generally made of lightweight material like polyurethane, steel or fiberglass. High impact spoilers may even combine two or three materials. These materials are flexible, hardy and do not sag. Car spoilers come in different weights, so the mass they add to your vehicle varies. A good spoiler attached to the rear reduces resistance and enhances speed and performance.
