My understanding of a diffuser is to reduce drag by increasing the percentage of laminar airflow from under the rear of the car, effectively (after tuning and research) helping the air pull the rear end down by keeping the air attached to the surface. You also see alot of cars that have upward facing vents behind the rear wheels to help that turbulent air exit out and up, hopefully pushing the rear end down. At what speed all this work is effective I have no idea so I'd guess you'd have to look at successful example (supercar or racer) and find out from that source what works. Of course the rest of their design has to be taken into consideration also but I'd think that some copying wouldn't hurt... Any and all comments are welcome as I well may be up in the night on this.

Or we can google images and results of wind tunnel testing on a brick with vortex generators installed... (IMG:style_emoticons/default/confused24.gif)
