Vortex generators benefit cars that have rear wings because it keeps the air flow hitting the top of the rear spoiler for optimal downforce. It helps the air flow make a smooth transition flowing from the roof and deflecting off the rear spoiler, rather than having the air crash in the low area between your windshield and rear spoiler.
