I've had my car for 1 year and half already

Trust me on this, it made a difference.

I don't consider it huge, but a noticeable one.

The roof spoiler goes for $335 before tax at renick motorsports.

Installation took 3+ hours.

What was the install like? And who did it for you? Did you just drill into the c pillar and are there any fixtures that you have to install on the inside of the c pillar... removing the headliner or anything?

still the ugliest thing I have ever seen...regardless of how planted your tores feel and not worth 335 plus labor by any means

wow thats seems expensive. for those that don't believe it makes a difference. there is a reason why subaru put that roof vain spoiler on the car lol its not bling bling. It's suppost to Aid the existing Sti spoiler in downforce or something.

instead of going with the vortex generator like the MR...this pulls down the airflow just enough for the upper portion of the wing...haven't heard how much of a difference it makes to the already 60lbs of downforce @ 100mph, but i'm sure the Subaru engineers knew what they were doing...

i'm planning on getting one too...but fo damn sho it's not for looks! haha

Function > Form



hoping it'll make the adj. SYMS wing even more funtional


but PLEASE dont forget to add more pics! i love it... functional parts like these make me happy...hahaha...people see it and think it's ugly and bet that it doesnt do a damn thing...but when you're the one in front who cares...

More planted during acceleration???? Must be nice to have so much power that traction is an issue above 100 mph!!!!!!

I should say, traction WAS an issue

The roof vane is there so WRC cars can have one I believe. From what I've read the production cars have to have a similar device for the rally car to legally have one.

i too thought that was kind of weird...him being able to tell a difference under acceleration...

the purpose of it is to give the somewhat funtional wing even more function...people have reported a difference on the track without the stock wing (STi wing & even WRX wing)...they say that it feels more planted above a certain speed (of course on a TURN on the track...not no acceleration bs)..

i wouldn't know because i've always had my wing and always plan on having one...if it's there to keep it that much less squirely on turns, it'll be that much safer on the road, and that much faster on the track...if i remember correctly there's an illistrated demonstraion of the roof vane's purpose on the Subaru International site (06' STi Video)...

the last poster has a good point as well, about them needing something on the production vehicle to be able to use it in the WRC...

if you look at the location of the stock wing it does appear to be a little too low to catch any "clean" air coming off of the roof...that's why Chargespeed makes the wing adapter that both raises the wing and brings it farther back off of the trunk, just like the WRC cars...because they're already done that on the WRC cars (higher and farther back) i'm sure the roof vane is even more of an aid for cleaner/smoother air over the upper portion of the wing..

Under acceleration, all the weight shifts to the rear anyways, thus "planting" the rear. Wing or no wing, you're not going to feel a difference in straightline acceleration. Simple Physics. But it looks good, at least.

You know what asses.... I't looks good man. I've been wanting to put one on my STi then go trunkless. O and yes while "one" of the functions of the wing on the rally car is to catch air off the roof, it's main purpouse is to keep the car planted on loose gravel during high speed turns. Suposedly the vertical veins aid the driver in keeping the ass end under control durring HIGH SPEED drifts.

why the harsh language and name calling?

the profile of the STi wing/WRC wing (without the "vertical veins") while going sideways is no where near optimal, with the "vertical veins" it creates the proper shape to acutally increase downforce. "Keeping the ass end under control" is somewhat right.

back on topic of the roof vane.

the STi website has a picture of what the vane does, and the direct translation (using google translator) is: "The Rear roof vane catches the crazy air" which is exactly what some people are saying. the only way to prove it works would be to get it into a windtunnel and measure the downforce.

the STi wing now (MY05 and prior) made 50lbs of downforce @ 100mph according to multiple magazines. but i could've been missinformed.

either way I like it.

I can't tell you that the roof wing does in crease the Laminar flow down the rear window,drive in the rain and watch. Also from about 80+ the upper airfoil of the trunk does not vibrate as much as the 05's did!! But what would i know i'm just an airline pilot

tell me your kidding.

it doesnt not feel more planted during "high speed" acceleration.

actually going wingless is better for just pure acceleration. if i was going for one of these vortech generators i think the mitsu ones are better designed, subaru ones look like they would cause alot more drag then the little shark fins. im leaning towards the chargespeed ones.

If all the weight shifted to the rear, the car would flip over. Perhaps you need to re-take elementary physics.

Vortex generators and wings/airfoils effect airflow differently the vortex gens maintain the boundary layer so you don't get the swirling or eddies around the area of the rear window as you do on most sedans.
The wing on the other hand has a constant Angle of attack which as speed increases gives more downforce.
I don't think Chuck Yeager could tell you that he noticed more or less downforce with this wing ,but the handling might change ever so slightly!!!

I like that the idea that function > form is best expressed by a sticker that says function. LOL.
