Yeah that will come eventually. I actually took a class during my masters on titled "automotive aerodynamics" taught by the head of aero at BMW in Germany. And one of our hw assignments was to design a rear diffuser. ie the angle is slopes up at, overall length etc...
Unfortunately most diffusers need relatively "fast" moving air underneath the car to really work efficiently. I think I have said it before, but having extended "lowered" side skirts and a flat under tray are almost a must for a diffuser to be effective.
On pure race cars the diffuser essentially "throws" the air upwards out the back. And in this universe, if you throw something up (air in this case) you will be thrown down by and equal force. That is why some of the German touring cars have such huge diffusers sticking so far out the back. This is further helped by a rear wing which also has "thrown" up air and now left a gaping whole for the air underneath the car to fill. The diffuser points the air from underneath the car where to go: up and outward. This is the reason some use multiple fins, to make sure the air is going straight out the back and not swirling around making a mess of things.
Something like the one we made can be helpful by doing this secondary effect of "pointing" the air in the right direction and giving it a smooth surface to go along on the back 1/4 of the car. I am not claiming that ours is totally a race piece, but I would bet in a wind tunnel having a big smooth piece like our diffuser with fins telling the air where to go, would definitely not have a negative effect. I would go as far as to say it would reduce drag slightly. Especially combined with a front splitter, which MP3Racer is sending us the mold for here pretty soon
ok no more aero for tonight so I will leave you with some pictures from the shop this past week. Kinda eye candy type stuff
Oh yeah these trunks, 6.5 lbs!!!!!!!!!!!!! and that is mostly fiberglass. Vacuum Infusion is a beautiful thing. I am tempted to make a full carbon one weighing in at 3.5-4 lbs to to see how light I could make one. And they are stiffer than the stock ones, and use all the OEM hardware to mount. These make a Seibon and VIS trunk feel like an anvil.

Mad bombing?? Lulz. No one speaks like that on this forum. And your question made no nickle, dimes, penny, or dollars. No offence in any way.
Thanks for clearing it up
