A car spoiler is an automotive aerodynamic device that is used to is to ’spoil’ the unfavorable air movement against the body of the car to disrupt the motion of vehicle -for better traction and faster speed. Car spoiler helps stabilize the vehicle by decreasing lift that can cause unwanted obstacle for a car that is running in speed. Customized and “cosmetic” car spoilers found on expensive cars helps modify the airflow as it passes though. But the truth of the matter is if you want to obey traffic laws and not get ticket then you are not going to go too fast to notice much of a difference.Yes, spoilers are often used in sports and race car for high performance function, but it is also used for common street vehicles too.

A good spoiler or wing with a well adjusted deck can make the difference between losing a race or winning it, all else being equal. Be sure not to confuse the automotive spoilers with the wings of vehicle. They are two different things. Vehicle wings are just there to drag and generate forcedown or downforce whenair passes around the car. Racecars and highly customized vehicles use car spoilers to reduce drag and improve handling at high speeds.
