I am getting aero package for my 06 g35... and it adds a spoiler and "Rear side air diffusers"
Can anyone tell me what eactly is Rear side air diffusers... Is it goan make my car quieter or louader or wat?

sorri for such noobie question

 

The aero package diffusers go underneath the car...actually right in front of the rear wheels. They are plastic diffusers, similar to the one in front, used to guide the air around the rear tires. This (along with the rear spoiler) supposedly drops our coefficient of drag from .27 to .26. Underbody diffusers are supposed to create an area of low pressure under the car, which should pull the car towards the gound (i.e., less lift in the rear)....making it more stable at higher speeds (maybe 100+).

Oh yeah, doesn't make it louder or anything....just supposed to make it more stable at higher speeds.

 

Sedan or Coupe?

Here's a picture of the Sedan's Rear Diffusers.
