from what i see it seems that the diffusor does not do anything to change the speed of the air over it ... seems to be just a flat piece with straight guide vanes ... that's not a proper diffusor if that is the case. can't seem to see exactly from the pictures. would seem more like simply a flat undertray ...

you sure you were shorted hardware? Give the guy a break, he had 35 orders to place with people asking everyday where is it. Buy the front splitter from him and mention the canards im sure he'll give it you.

The point of a diffuser is to provide a smooth and direct path for air to flow around the car. Take a peek under the S and you will see a ton of places where air can get caught and cause turbulence, therefore negatively impacting the aerodynamic qualities of the car. (The rear fender makes one heck of a parachute). The flat panels provide the smooth surface, preventing air from getting into the crevices in the rear of the car. . The fins keep the air moving in a straight line as it exits the rear of the car.

I'm fairly certain the canards were a bonus for his other group buy, not the diffuser.

Nope I was apart of this group buy. They might not even be canards. I'll take more pics tomorrow. Also, shitty ups damage the the box and that caused one of the corner of the diffuser to bend. Now I have to try to bend it back.

^All that has already been covered...The diffuser is not flat, either! It has a \____ kind of look, the front piece is angled upward to prevent air from getting between the undercarriage and the plates.

just FYI - a was done at racing forum - a guy drove at race track with rear bumper removed - top speed at lap times remained the same.
