Question Aerodynamic Improvements

I have been doing alot of research about the areodynamics of my GT and came up with a few ideas that others might be interested in. The wing of the fiero does damn near nothing if anything. It needs to be about roof level because of the fieros design. The diagram below shows why. If your satisfied with the wing or don't drive fast then more power to you but if you drive 100mph then you might want to upgrade your wing/spoiler. Spoilers only create downforce when they are in clean air.



Vortex Generator. This is a "VG"

It helps improve a spoiler/wings ability to create downfoce. It comes stock on the new evo 8 and many have already copied the design. The funcionality of it on a fiero hasn't been tested yet. On an evo it decreases turbulent air. It affects the boundary layer of air flow. Not sure of its effectiveness, but it's one of the hot topics right now and thought I would inform people about it. The same pattern of "bumps" can be found on the front roof of many trucks. Take a look at the way the cab roof lights are set up.....same shape and similiar pattern . Think its an accident they are set up that way.....I think not.


To increase downforce up front there are canards


There effectiveness depends on how many you have, their placement, their angle of attack and how fast you are going....yet they do add a considerable amount of downforce.


There is also the front/chin spoiler


These don't actually create downforce by themselves. They direct more air into the radiator area (depending on design). Alone these will create a more aggresive look and INCREASE LIFT, BUT when you add a hood vent or extractor scoop the chin spoiler will increase downforce. This is because the air that is being directed into the radiator has no where to exit. So if you add more air that has no where to go that will result in more lift. You add the vent/scoop and the added air has somewhere to exit. Resulting in increased downforce.
The downside of this mod is the price and if you low you fiero you will need to take extra caution so you don't scrape the spoiler.

The next best/cost effective suggestion is to take the bottom section of another aero nose bumper...flip it upside down and mount it this way. This type of bumper mod is more for looks for than function. The upside of this is that you don't have to worry about ride height and the mod can be done for very cheap. Plus it looks damn good.





The best and most important mod to keep your front end stable when driving fast is to put an extractor scoop or a hood vent directly over the radiator compartment. I have a 6x6 hole over my radiator compartment and it helped tremendously...going 130mph felt like 60mph.



I need to read more so this is it for now. Tell me what ya'll think.
(None of these fieros are mine, just posted for examples.)
