rear wind defuser
 

does any one know were i can get one at?

what is that?

Is that a spoiler on the top of the rear window?

well what car and year might help also. i can get pretty much all the wings west stuff so... pm me

Not at all. It's this metal plate with holes in it that is installed in the rear bumper. It allows air to escape through the rear bumper, reducing drag and increasing down force on the rear of the car. It's mostly used for top speed cars.




Last I knew, STR and Top Fuel made air diffusers, but they're really tough to find.

thanks

summit has them
