Whoa!!... Here are my replies to each one of you.

Brainstorm,
Read Mike's second post in this thread...Nuff said.

setwas,
I think we are on the same wave-length(under-body stuff).

morepower2,
We ARE on the same wave, thank you.

XtremE,
Just for adds? I dont think the worlds best/fastest race cars would sacrifice the weight and areo drag of a wing to get more adds. D-force counts in triple digits..Thats where I am going.

James,
Venting the hood wont help you say, you know those big openings for air in the front of cars..to let air hit the radiator??? what do you think that air does after that..disappear? No it creates a high pressure bubble under the front of your car effectively lifting the front end(making a understeer prone FWD even worse). Tottaly tape off the front of your car(leave a small opening for cooling air) and go for a high speed run, you will know what I am talking about.

Here are some of my other thoughts on car aero.

Lips/splitters: Put low enough they help divert air, stopping some from going under the car and becoming hella turbulent. Creating some "weird happenings" and lift down there at high speeds. This is where under-trays and diffusers come into play.

Under-body stuff ie. trays and diffusers: designed properly will smooth out that "dirty" air, and possibly create "suction". Do you think an F1 car gets enough down force to squash hella stiff springs and theoreticly run upside-down, from its front and rear wings? I don't. Wings that good would create hella drag.

Rear spoilers: depending on the tilt of the rear window(20deg I think) air will not "stick" to it and flow down to a oem(read useless) spoiler, and if it does the air will be so "dirty(read tubulent) the spoiler doesnt do a hell of a lot. Think of this.. cars with a rear window less than 20deg, that have a wing and a rear wiper dont utilize the wing because the wiper "dirtys" the air. For a sedan like say a B14 you need a wing that will peak up into the "clean" air over the roof of the car. I may look "rice", but its less rice than riding around on Sportlines with stock length struts(I'm guilty on that one).

Did I forget anything???
For those that think I am "ricing" or not going to acomplish anything with my aero ideas, remember this when a Charcoal Mist 99 Sentra XE blows by you on a corner because its sticking and your sliding.

"We mock what we dont understand"

P.S. Every "real" racing B14 I have ever seen has a wing.
