Acceleration Activated Wing
I have some wings for sale that change position depending on how much your car is turning. You can email me or see more information here: www.darkspeedwings.com

it's not that, but premium member, selling stuff, less than 10 posts...all in the same month?? it's a bit much to swallow all at once. Plus, it appears no one can vouch for you, and to be honest, these guys are a bunch of skeptics anyway.
besides...large rear mounted wings on a civic, let alone one's that auto-adjust with steering angle? just don't see the need for it on mostly street-driven cars that barely see 100mph and very few that hit more than 140. maybe you'd have better luck on a mustang/supra forum?

Rep Power: 0 My apologies for registering to be a vendor and putting a commercial posting in the classifieds section... I’m not sure of my crime, but I’m sure several of you will let me know. (I'd be happy for the admin to remove my posts if there is a problem.)
Meanwhile: Yes, I agree that wings, spoilers, aero kits, have minimal effect at normal street speeds. The “adjusting” wing only improves top speed by ~1.7 mph on a Civic over a fixed wing. Fuel savings are not even measurable unless you consider the savings over distances such as 10,000-miles. Probably not worth the hassle if someone wants a contraption like that for function alone.

To quote wikipedia.org
"Spoilers generally work by disrupting the airflow going over a car. This disruption has the primary purpose of reducing the amount of lift naturally generated by the shape of the car.
The result is increasing the contact between the tire and the road surface, thereby increasing traction. This increase in traction allows a vehicle in motion to brake, turn, and accelerate with more stability. Additionally, this is accompanied by an increase in aerodynamic drag.
In nearly all cases, drag increases as the speed of the vehicle increases. Thus, some spoilers that are effective at very low speeds often generate excessive drag at high speeds, and spoilers that work well at high speeds are often ineffective while moving slowly."

Is this what you are trying to over come with that pos that moves up and down?

its like the porsche wings i'm assuming... honestly its not a bad idea, its different. May not impressive civic owners, but beemer guys would love something like this. YOu'll be surprised what kinda things BMW owners have on their cars. Its unique nonetheless given that it works the way its supposed to.

Rep Power: 0 Kevbortron: thanks for the info on the forum, my apologies.
Kevbotron, Boggie, Kasimmmm and others:
In short, aerodynamic drag (which is most of a car’s total drag on a freeway) is composed of parasite (skin friction) and induced (vortex, or pressure) drag. Wings and spoilers typically influence both of these drag components. A small amount of downforce produced by a wing/spoiler can reduce induced drag but too much downforce will actually increase induced drag. The wing/spoiler will generally always increase the parasite (skin friction) drag force of a vehicle. These drag relationships hold true regardless of the speed of the vehicle, they just matter more at higher speeds. (they actually increase with speed squared, so if you double your speed , your aerodynamic forces quadruple)
The best angle-of-attack for a wing (when the car is going straight) is just barely negative if drag is the only consideration. In different words: the wing is nearly level, and producing very little force the car will go the fastest. However, when turning, it is desirable to have more downforce, but that comes at the cost of increased drag force (mostly induced, unless the wing is deflected so far that flow separation occurs).
By putting an actuator in the wing and controlling it by a microprocessor, the wing can be set to the lowest drag position most of the time. When the car experiences lateral acceleration (going around a corner, changing lanes, etc), the wing moves to the higher downforce mode, but at the cost of increased drag (but just momentarily).

Rep Power: 347 I saw one of these that retailed for 749 made with Carbon Fiber....
Oh, it is the same person with this website. I didn't even see the link in the first post

not to knock you man, everything you just stated makes perfect common sense and can be found in any reference book concering aerodynamics of cars, especially in a race application. had any of the guys flaming you taken the time to think about it, they'd have come to the same conclusion. and yes, while the product may be quite functional, i've found that my civic tends to be more unstable in the front end at elevated speeds...but i'm not mounting a wing on the hood and i don't really like the look of the c/f splitters, so i guess i just have to drive slower....
