I'm still unsure about this. Anymore pictures from farther away? Thanks!

Any chance someone has the STI sticker for this but doesn't want to put it on? I realized mine was put on a little off center and I want to redo it. Unfortunately the adhesive seems to be a one time use so I need a new one

Forget the cheap sticker and buy a nice aluminum or stainless one off ebay. Far nicer and better quality :thumbup:

I would but I can't find anything small enough to fit it

Hmm thanks I'll try it out!

I know it is a silly question, does anyone feel any different in high speed? Before and after install? I guess this is mostly for cosmetic purpose?

Well, per STI:

ATL BRZ might be the only one besides switchlanez that hasn't put away their BRZ for the winter that might also have the gurney flap and have had an opportunity to drive at "high speeds" with it. I know ATL BRZ has for sure, so hopefully he'll chime in.

Lol, the butt dyno is inadequate for measuring CD!

I'm hoping to order this on Friday. No drilling holes, just prepping the wing and chopping the screws. I'll keep the STI badge on there, too.

You actually have to apply the STi sticker. It doesn't come pre-applied.

I added a metal badge to mine. Came out nice.

Sweet!

Please don't flame me for this guys, but just the other day I was at Home Depot and saw this piece of black rubber modling in the plumbing section that looked just like the gurney flap wing. I was tempted to measure off the section and try it for fun. :happy0180:

From further away

Do it. If that works for you. the NASIOCers have been using garage door trim for years as a front skirt lip alternative. The rear should be no different. :happy0180:

That's what I meant. It's MEANT to go on there, so I'll follow through with its fully intended purpose. haha

:word:

I did track mine at full speed for the first time in early December, but I hadn't done any really high speed driving before installing the flap, so I can't really comment on that with any validity from my own personal experience. I am however certain that it's functional. The same design application is all over the motorsports world.

If you look really closely you can see the vortices coming off the back of the wing from all that downforce pressure squeezing the moisture out of the air... :lol:

^^^ nice pic!

Awesome pic!! Thanks for sharing. You really can see those crazy vortices flyin!

so....installing the Home Depot molding may result in some smaller vortexes?

:lol:

Any tips on installing this?

Not really. I test fitted it a couple of time where I wanted it. Peeled the sticky tape back on the left and right sides. Lined everything up, presssed and then peeled the tape out as I was pressing along. Last I drilled in the holes, dropped in the anchors and applied the sticker.

So this thing costs $136 + $80 shipped? Anywhere to get it cheaper?

Nope it has to be imported directly from Japan. Afaik japanparts is the cheapest.

Just wondering where you found the metal badge?

You find them all over ebay :thumbup:

Yeap. Just search for "STI front lip aluminum badge."

Thanks JPxM0Dz for that btw. :happyanim:

This is not really true. A gurney flap or wicker changes the flow characteristics at the trailing edge. A small vortex (twirling air) forms behind the flap. This helps decrease the boundary layer (layer near the surface with rapidly changing tangential velocity where shear stress is not negligible) on the low pressure side (bottom of airfoil on cars) increasing the effective camber of the wing. This is how the downforce is gained on gurney flaps. It does also increase the high pressure zone at the top of the wing, but not enough to do anything (low pressure side is where all the work is done :D)

Is it possible to put vinyl wrap onto the gurney flap?

I want that flap bad!
However, the sharkfin antenna from the PDF would be nice to go with it. I can't find it on japanparts,though.

Yerp. The flap is the cherry on top. I'm working with J-parts now to get info on the antenna. Yuki is out on vacay. When he gets back we should have some info.

The weird thing is that i cant find it on STi's official site, either. Anyway, PLEASE let me know as soon as you figure sth. Out

Yerp. Not on the STi site but it is on the Suby site: http://www.subaru.jp/accessory/catal...3newoption.pdf

Just put mine on this weekend...

it'd be cool if someone made a cf replica of this
