I just got the aero package installed. On the invoice, it says that the spoiler and rear air diffusers was installed. Can anyone tell me what the air diffusers are? Are they the extensions of the rear bumper that I see on the 6MT coupes (I have a 5AT). I don't see anything else installed besides the spoiler.

 

they go under the body..underbody air diffusers

youd have to go under the car to see them

 

What do you call the things that are on the bottom of the rear bumpers? My car doesn't have those but I want to put those on.

 

I think you're talking about "mud guards" which comes as a set for the front and rear.

 

Yeah I think thats it. They make the car look much better.

 

splash guards..get them from your dealer or mynismo.com

 

The diffusers are those black plastic plates installed under near your rear tires. I was told that it suppose to help with keeping the car hugging the ground; thus achieving its "zero lift" blah blah.

I recently got mine installed.
