Question Anybody know if the RS wing "works"?

Is there any test info showing downforce generated by the stock MY00 coupe wing versus others?

I'm thinking of taking mine off for stealth mode around town and I'm too old to look like a ricer

If the wing really creates downforce, I'll use it for track days.

If you take it off you better attach wieght to the trunk lid. Otherwise it will spring up really hard and remind you that you took off the wing.

No data, but from driving hard in the rain I *think* it keeps your butt planted well.

Of course it works! It works to slow your car down!

It does aid in high-speed the stability of the car. I think it was last year during the One Lap series, SCC had a WRX running around doing the one-lap race events. They didn't have a spoiler on the car, and they noted that the rear didn't feel very stable. At one of the events, they swapped trunk lids with an RS that had a spoiler. With the spoiler, the car felt more stable.

I think the wing is in a neutral position. Take it off..

Wing DOES NOT DO ANYTHING. I suppose its main purpuse to prevent trunk lid from flying up.

I've got three comments on this one:

1. If you're concerned about stealth, I'd worry more about the front of the car...
ie : fog lights, hood scoop, hood vents...

2. The wing is shaped like an airfoil, in the proper manner to generate downforce - how much however, I do not know.

3. Ever seen an STI version 2??

Trust me - the wing works.

nope.. it's true.. the wing does nuttin.

even though it may be "airfoil" shaped.. it's not in any real air flow.
our cars are so tall, nothing hits the wing other than random turbulence coming off the roof.

I've got the prodrive/RB5 wing.. and I'm doubtful that even does anything worth mentioning... it was even designed by the guy that did the Mclaren F1..

just enjoy it for it's looks and headlight blocking ability.. all it's good for.

I think that to create any true downforce at lower speeds the wing would have to be higher. The reason that I feel this way is because when it rains the water just sits there on that back windshield, there seems to be almost no airflow down there at all. Strap one of those "superbird" wings back there and see what happens. No wait, better not that would look really stupid

The wing actually DOES do something... I had a friend that went wingless for a bit and he noted that the back end felt rather light when driving behind big trucks, but with the wing it stayed planted.

And I like to go hang out and use it as a picnic table too.

The wing works as a spoiler, which reduces lift at high speed rather than generates down force like the big wing on F-1 race cars. The spoiler breaks up the laminate air flow coming down the rear window, thus reduces lift. So the wing does reduce lift and enhance high speed stability.

edit - and it looks cool even when the car is not moving

It might start creating downforce at really high speeds (i.e. < 100 mph) but other than that, I believe that it is all just cosmetics.

Below 110 or so my car felt unstable but by 115 my baby settled down so i think it supplies some downforce at higher speeds. B.T.W to you people that said the wing is too small to produce downfoce b/c of the high roof, just look at porsche low spoiler actual downforce. And audi actually recalled the TT because of high speed wrecks on the autobahn. Reason being instability at 140mph+ so what do they do? put a dinky little ducktail on back to level it out better ( I'm sorry if I was rude but its 2 a.m and i have been up since 7 a.m working)

what slamck said.
Its a spoiler. It prevents lift, not provides downforce. A number of months ago someone posted complete wind tunnel results with most of the subaru wings. Cd effects, downforce, lift reduction, etc...

Personally, i think its nothing more then a stability spoiler, and a drag indusing extrusion on the car. Because of the simple principle of that, it will staplize a car at high speeds, as it helps to shape the air off the top of the car more efficiently. But i seriously doubt it actually generates any down force. It would have to have a preaty nasty rake inorder to acheive any actual downforce.

The comment about the TT and the Porche is preaty rediculas. Look at the TT and the Porche, both of those cars are wind tunnel shaped and tested for efficiency. THe body designs are so smooth and flowing that with enough lube, you could probibly stick them just about anywhere. With that in mind, the air flow over these cars is very percise, so it doesnt take much, in a high presure air flow area, to make downforce, and add stability.

To that end, the Impreza is not the picture perfect image of aerodynamic design. In fact, in all honesty, its a brick. So the chances of getting good aerodynamic shaping over the body of the car, are not very likly. So where there is some aerodynamic stability to be had, they make the most of it. Which is why the customary large rear wing. To give the car some stability where it had none. Somthing i think i should point out is that i use the word "STABILITY" not downforce. Look at the CUsco Impreza AJGT car. The front end has been chopped, the roof has been chopped, the whole car has been completely re worked, and tweaked. And they have a HUDGE rear wing far about the rear deck of the car.

So, final word... Stability? Yes! Downforce? NO!

It gives a little drag but, it doesnt do anything untill over 100mph. How often do you do that?
PS, Would you maybe sell it?
