2006 STI Roof Vane Spoiler part 1

2006 STI Roof Vane Spoiler
[IMG]http://img.photobucket.com/albums/v310/deterioration/NASIOC/06.jpg[/IMG]
I�m sure I�m not the only one with a WRX that has seen the 06 STI Roof
Vane Spoiler that is either curious or thinking about bolting one on.

I had a service appointment yesterday so I asked Parts about how much
it would cost how was it fastened to the car etc; I was quoted about $510+

I�ve read �A new roof vane spoiler, inspired by the Impreza World Rally
Championship competition car, contributes to stability at track speeds
and reinforces the car�s high-performance attitude.�

I still have questions:
What type of material is the main [Black (96021)] part made of?
Are there vendors willing to sell it at a lower price?
Is it functional or cosmetic - meaning at what speeds does it become
functional? Like the Rear Spoiler at 60 MPH depressing the rear 1�.

Thanks in advance! :cool:

Ive wondered how funtctional it is also. Because i do like the looks of it on a STi.

Of course it IS functional....... but everyone missing the fact that [b]2006 STi is lower[/b] then 2005 STi !!!
Legba 03-08-2006 02:01 PM

Lower? By how much? First I've heard of this.
digitalmethods 03-08-2006 02:10 PM

It just directs the air to flow better over the car. It's not worth the money IMO. Go to a dealership and see what they are made of. Just looks like a small rood spoiler. In a couple of months you could prolly get a CF one at a cheaper aftermarket price.

what does it being lower have to do with anything?

[QUOTE=captain spaulding]what does it being lower have to do with anything?[/QUOTE]

a slight change in aero dynamics can cause a huge diff in performance and handling...the lower the car is to the ground the less likely it is to lift...the roof vane spoiler probably ...if this is the way it works ..adds more downforce to the rear...but personally ..i would get the sti lip before i get this...
cMags 03-08-2006 02:47 PM

There was a thread about the '06 roof vane earlier on, and the general consensus was that the roof vane without an STI wing would actually DECREASE the downpressure on the road at speed.

The roof vane directs air coming off the roof downwards, causing a bit of lift, but combined with the STI wing, it allows the wing to push more air up therefore creating more downpressure. That's why its only available on the STI with the big wing.

Without the STI wing, it would just be acting as a wing, lifting the rear end a bit which is not so good. Looks cool, but adversely affects handling unless you also add a wing.

[QUOTE=captain spaulding]what does it being lower have to do with anything?[/QUOTE]
There is a word - "aerodynamics". I don't want to says it won't work... but SUBARU say it helps to get better airflow on the rear spoiler = more pressure on the back. But it's position (higher/lower) make sense on how airflow do its job.

But sorry, my mistake - I checked again and looks like I had wrong dimesnions data :eek: Yes, it's longer, but not lower - same 1440mm :rolleyes: Sorry :)

Thats why you don't see the roof vane spoiler on STI's without the STI wing... For example: the S204 and the new UK version STI... the Spec D.
SubyWRXSti 03-08-2006 04:30 PM

if you don't have a STI rear wing, it's best for you NOT to install the roof spoiler.

The roof spoiler acutally produces air that "lifts" the car, if you do not have STI wing, or some kind of wing that is about the same height as the stock STI wing.

This roof wing optimizes the angle of wind going to the rear spoiler, which as a combo makes great downforce. However, if your rear spoiler is too short all it does is create lift to your car. This is part of reason why S204 which has a shorter rear spoiler does not use this roof spoiler.

There is a picture on Subaru.co.jp
[url]http://www.subaru.co.jp/impreza/wrx/mechanism/03/index.html[/url]

it shows how the air flow through the whole set up.

Here is a short paragraph translated using altavista about the wing set up:

"Furthermore, the roof vane which is installed in the roof rear end of STI raises the effect of the large-sized rear spoiler by the fact that the air is let flow with optimum angle."
Picard 03-08-2006 04:31 PM

FYI, there's a group buy going on right now for a carbon fiber version that's much lighter than the stock one. If you read the thread they've just made a version for pre-06 and will upload pics soon:

twizzstyle 03-09-2006 12:01 AM

Honestly, they can tell you all that stuff about optimal angles and such, but when it really comes down to it, that wing is helping the flow stay attached, and so its main purpose is to decrease drag, nothing to do with lift or downforce. Does the same thing as vortex generators, it does the same thing as spoilers on the back of many SUVs. Decrease in drag.
XanTium 03-09-2006 12:15 AM

See when I read splitter... I think of splitting the air into two main "currents". The way its split it looks like it cuases one stream of air to hit the upper part of the wing while causing the other stream of the split air to hit the bottom part of the wing/trunk.

Honestly... almost ALL road cars produce LIFT at all speeds. I remember hearing something like 95% of all production cars at least. All this stuff is doing is trading drag to get rid of a little bit of the lift the body design is getting in the first place. Honestly though... without a lot of underbody work there's not really anything you can do about it... and I don't think that 1x1 foot plastic "diffuser" thats under the spare tire on the 06's is going to help at all.
layzienoy 03-09-2006 12:24 AM

the vortex generators on the evo only have an effect at high speed i remember on an evo forum someone saying along the lines of 100+mph at which it doesn't mean much on roads

as for the roof vane get it if you like it
thisisbrock 03-09-2006 12:48 AM

ive thought about getting it as well. i just know it would be a PITA to put on the car.

its functional even on wingless and it looks sexy.

You are correct.... but remeber that the 2006 STI has an additional 4 panels under the car... as well as the 2005 STI. So for 2006 the rear diffuser, the two under side panels the front engine cowl, and the roof vane spoiler all probable have a noticable difference compared to an STI or WRX without those additions.

Your desription of the roof vane spoiler is perfect... it is meant to work specifically with the STI wing.

DTECH-WRX 03-11-2006 12:29 AM

The black roof vane is actually metal. It feels like a very heavy gauge aluminum or even steel when you tap on it with your finger. The small covers that go over the mounts that are body colored feel like the same material as the bumpers more or less.
hanzo918 03-11-2006 02:52 PM

I think that's more of the answer than anything else. Subaru trys to chop off everything to save weight on the S20x models. Maybe it is dependent on the large sti spoiler, but I'd bet the weight has a lot to do with that decision as well...

That has got to be the most pointless product ever.

The roof vane is there to direct air to the STi wing.
The vortex generators are there to create turbulence and bring down positive onto the extremely angled Evo rear windshields.

Combine the 2 = drag + turbulence + lift = what the...?

Aston martin's also have 2 or 3 times as many cylinders too. Put a V12 in a subie and I wouldn't care about weight either :p

And anyway, the S20x cars are meant to be track cars where acceleration is just as if not more important than top speed, so weight is definitely a factor... It may or may not be the reason for the deletion of the part in question, but it's not totally rediculous to think that it could be...

Aero != top speed

[SIZE=2]Aerodynamics The MY06 Impreza STI features a completely revised aerodynamic
package compared to the previous MY05 model. Additions include a WRC look front
bumper which generates frontal downforce, also front corner spoilers and grilles.
These components provide air extraction from the area behind the front bumper,
and improve the airflow down the side of the car. The new roof vane combines
with the rear diffuser and boot spoiler dramatically improves the aerodynamics
for improved stability and handling. The roof vane catches the airflow from the
roof and directs it to the rear spoiler thereby enhancing its performance. The
rear diffuser smooths the airflow under the car helping to create a smooth
airflow on exit. The co-efficient of lift (CL) performance has improved from
minus 0.045 to minus 0.075. (Greater down force) which is a 67%
improvement on the MY05 model[/SIZE]

I think the vortex generators for the WRX are ugly because they are much bigger and bulkier than the sleekk Evo ones. The Roof Vane is functional on the STi, if it wasn't it wouldn't be on the SWRT car. I agree that it is not really beneficial for the wrx but I would expand the statement to include wings other than the STi spoiler such as chargespeed, syms, wrc replica, etc, but not stock wrx or wingless.

Wow, that link has a lot of interesting information. Sorry to take a tangent here, but if you look at p. 28 "Theft Prevention" they have some things that I don't think we have here in North America:

- "dual stage security system"
- PIN operated keypad
- six-points of immobiliztion
- anti-hijack mode
- internal screamer
- anti-cross pollination software (?!)
- double-locking system
- shielded lock cables
- no key cylinder lock on tailgates
- DataDot technology

Is there any technical brochures for North American spec cars?

because it looks stupid without a spolier and no wing. Its the same as putting a roof scoop on a car with no hood scoop, it looks retarded. Most of the stuff they put on these cars is for looks, the target market for sti and evos in the us are males age 22-38. 90% of the people on this forum fit into that category. True, maybe at some heretofore yet unknown speed, these things become functional, but most of us will never need it for those purposes.
