On my prototype I can vouch for a mpg increase on highway cruise. The 7 of the pre-production version I have sent out, I have reports in of increase mpg on the highway.

I can't say a specific number because it will change based on so many factors.

I'd also love to have wind tunnel data, but I'm an individual, not a massive shop that is willing to spout bs "data" to sell things to you. My budget for r&d comes out of my rent/food/gas money. What I can give you is that this is designed and built on a basic and time proven application which has been used in the same manner on race cars and "elite" sports cars around the world.

If considered as a purely cosmetic piece, take into consideration that plenty have paid $600+ for a fake diffuser which is nothing more than a lip on the bumper and lets be honest, this thing is just pure sexy and makes people break their necks.

I haven't test fit one yet but it should fit if the exhaust is designed like all the other aftermarket ones.

Any word on pricing? I know what Carl was selling the pre production ones for and I should have jumped on that when I had the chance....

Via my Note 2

Understood. When you get pix of it installed, how about a profile, so we can see the diffuser angle, and the amount of "flat" floor forward of the angle. If you know the angle, that would be nice, even a side view of it uninstalled.

Pop rivets, or bucked rivets? any adhesive?

I'd have to send it out for black anodize myself.

*edit* You're moving to the Charlotte, NC area?

does this fit the STI/BRZ rear lip?

I'd be interested in this, especially if it works in conjunction with the purely cosmetic Subaru "diffuser"

I'll take one if it fits with my AFe exhaust ?

Next week on that announcement which will be in the classifieds. :)

Installed pics are being edited now. We will be offering this anodized in a couple colors. That takes time and adds significant cost as getting a place that has a tank big enough to do this part is hard to find.

It would not work with that piece. You would have to heavily modify that item or take it off.

It should work with it as AFE has similar design to the others mentioned to fit.

Very interested, PM with price if possible.

Greddy EVO 3 here too.

Looking forward to the pix. Anodize, powder coat, CT-41...I shouldn't have a problem around me getting it coated.

Install photos up on page 1 :D

Interested, but i would like to see some test data to quantify how effective it is.... and i Wish id did not stick out quite so far past the end of the bumper area.

This is exactly what I want, but anodized black!

Anyone got a wind tunnel to do some testing in? :)

Pop rivets, no adhesives. Im looking for an anodizer in NC, ft86speedfactory mentioned something about powdercoat through them but you'd have to ask them.
