If the wing flaps up and down constantly, alternately providing lift and downforce, then sure, it's useless, even worse than useless.

But if the wing is pushed down and flexes some in the process, then the downforce is transmitted to the car. Energy doesn't really figure into this. Sure, in the transient situation where you're getting up to speed and the wing starts to flex down, there's some energy expended (The force on the wing travels whatever small distance down as the wing flexes.) The force is still there though, and since the wing is connected to the car, that force is transmitted down to the wheels.

The world rally car would not bother with it if it were useless. Forget the data just show him a photo of the rally car
The latest rally car wing is even bigger and more complex to work in a cross wind

Bottom line:

If you are racing, keep it, or better yet, get the WRC spoiler instead.
If you aren't, make your decision based on what you think looks better, because at anything approaching legal speeds the difference is probably negligible.

I would like a spoiler that is functional, but doesn't look like the product of a ricer's hyperactive imagination. Not everybody wants a giant cop magnet on the back of their car.

For people with 06 STI. Have you driven them in the rain? How is thepattern or movement of the water in the rear windshield now?
Just to see how the new aerodinamics affect the air flow in the rear.

This is only based on "I read somewhere," but the figure I saw was about 50 lbs at 100 mph...on our 3000+ lb cars...that seems basically useless to me. I can see the vertical slats aiding in straight-line stability though.

O wait...maybe it's the bigger scoop helping to stabilize the car at high speed.
Well, you sure aren't helping. You're completely ignoring the fact that the stiffer bushings, stronger hubs, firmer shocks and greater weight in the STi means a more solid feel at speed. Chalking it all up to the wing is just a little silly.

the wing works ;
#1 it gets people to look at the car
#2 it makes a weird pattern of dirt and rain on the truck lid
#3 it get people to look at the car
#4 it makes people in cars with any amount of power [which they think is a lot] want to drag race you
#5 it gets people to look at the car
#6 hey bad enough we have to buy this sprots car with 4 doors, without the wing it would look like a camry or a sentra or any mid sized vanilla car.
i didn;t like the wing when i bought it but a week later it was no longer for sale.
and the rally guys [other than wrc] use this wing a lot, maybe they know something or maybe not.
#7 it gets people to look at the car

50 or 60, don't remember which, and I think 100 lb at 150 MPH. Whatever, try driving around with 50 or 60 lb of lead in your trunk. You will notice a difference! Don't ask how I know...

The new roof spoiler has the amazing ability to actually draw out any airborne dirt particles, combine them with rain, and deposit them onto my rear window. It definitely directs the air towards the wing. How much benefit this provides, I don't know. I do think it's kind of funny when people ask what that thing on my roof does and I tell them it's just there to feed the big wing.

I couldn't be convinced that the wing had enough value to performance to justify keeping it, so I went with a Mine's spoiler on a clean trunk and I think the roof spoiler looks much cooler now and car in general is very clean looking.

Motor Trend: Oct '04: "...provides about 50 pounds of downforce at 100 mph".

This is for an '05 STi, and I can't imagine they'd make it up, it's probably in the '04 Subaru Press Kit.

Wasn't it discussed a few posts ago that downforce is not equivalent to inertial force aka weight?

You can't take the downforce the spoiler makes and divide it by the car's weight. You have to take the downforce the spoiler makes plus the lift the trunk experiences without a spoiler and then divide that by the car's weight. When you simply divide the downforce by the car's weight you're assuming that a wingless turnk has 0 downforce/lift, which is untrue.

Shirokuma's thread provides the best answer. He's driven both back to back on the same track on the same day, and he says the wing makes a difference. Do you people really need more than the opinion of professional drivers to believe the wing makes a difference?

If you don't like the way it looks, fine, take it off. However, don't try to justify your tastes/beliefs by spraying misinformation all over the net.

Agreed.
#8 it gets people to look at the car
#9 it holds drinks, babys, and books.
#10 it gets people to look at the car, including the fuzz...rats!!

Frankly, if you like it, get or keep it, if not dump it and sell it to me.

How would you know if you're not getting down force? Can you ACTUALLY FEEL anything if someone was sitting on your rear bumper? How DOES 10hp feel?

Can you actually feel lift?

DO YOU THINK THAT THE CUSCO IMPREZA's HUGE REAR CARBON GT WING ADDS DOWNFORCE or is it just for looks? Do you notice how HIGH it sits? The height is because of the rear window. The wing can get a better attack of the air when placed higher on the rear of a car like the Impreza, which has a steep slope rear window.
you live in St. Paul, I live in St. Augustine. Agree to disagree. Obviously it does...but the question is not are wings functional. But HOW functional is the STI wing.
