[QUOTE=MRunner;3837483]I kind a notice the spoiler flexed after it goes beyond 120mph, by comparing to the parrellel defroster line on the rear windows. /QUOTE]

damn dude.. whenever i reach that speed.. i am afraid even to blink and my eyes are solid on the road.. i dont know how would you be able to do that..

There was an article out about the STi vs EVO aerodynamics -- posted on this site. The rear wing adds significant downforce, but if you want more you will likely add much more drag (it is all about trade offs).

Edit: Here is the article and post https://www.evolutionm.net/forums/sh...o+aerodynamics

The max down force is dependent on speed. Adding the wickerbill will give you more down force but more drag as well because I believe the wickerbill creates down force by re directing the air flow rather than creating a pressure difference like a wing does. To me, the wickerbill seems to act in the same general manner that the huge wing flaps near the fuselage do on a 747 or what not when you are landing.

well thats an easy fix... ya hop on i95 get up to 120-130 on a straight away... around bass pro shop is a good spot 5/6 lane highway... ya throw a brick on the gas and just turn around.. that way you can observe the wing for more than a second...

my .02 cents

i've only totaled 4 cars out of 11 doing this... so i think thats pretty succcesful
