Well it does help with wind deflection a bit which i heard creates less drag and less stress on the motor.

Purpose of a roof spoiler.

Roof spoiler is an aerodynamic device that is usually attached to the rear of car s roof. It gives the very rear of a car a turned up appearance. As its name indicates a spoiler spoils the smooth flow of air over the back of a vehicle. It is custom designed to fit the upper window section and installs directly above the glass.

Most common spoiler functions include disrupting some type of airflow passing over and around a moving vehicle. However it is mostly now done for looks as it is an optional accessory same as the front bumper lip etc. But that small disruption can have a major impact on overall aerodynamics. The function of a spoiler varies depending upon the location where the carmakers install it i e.

6 nov 24 2010 the initial purpose of a spoiler is to break up the airflow from the back of the car to reduce drag. Which effect it is going to spoil. A rear spoiler is that small piece of trim that usually extends from the edge of the trunk. Then in return adds an extra 20hp or so to the wheels.

The most common function of the spoiler is to reduce the effect of the turbulence created by the airflow. Most of the roof spoilers are custom molded and need no modifications to mount.
