That one sure is purty... I love my 40buck APR GT wing on track. Show cars selling their real bling parts ftw....

Ignore the rake here... had just mounted it to the spare track trunklid.

******* LOVE the paint on it. Little Renown 787 If I was to do anything other than single color, it would be that. Id imagine that wasnt cheap (or easy if you did it yourself).

Any way to mount the ISC dam in a way to break away from the front if you went offroading, without it coming off from wind forces, or touching another car? Maybe just less bolts. Either way, it would still mess up the front. Also, what is the point on the fiberglass hood at only a 2lb loss? A healthy bump could lose me more than that, or removing a layer of clothing. I guess to some 2lb is worth it, when everything else possible is gone.

It just needs a metal frame. You can't expect to mount it to the bumper and have it stay on. I'll do a big metal frame for it as well as a splitter under it.

I used industrial grade velcro for a spoiler on my ITA Miata, but it weighed far less than the ISC piece- and had WAY less down force. Was more for keeping the air from under the car. The ISC piece is fairly heavy (relatively speaking), so it would probably require the actually product and session under the car to figure something out.

I failed to mention that the ISC also made a huge difference on the tire wear we were seeing on the fronts. It virtually eliminated any push we were seeing on turn-in - thus the higher entry (and exit) speeds.

Here's the aftermath of the off and the process to remove the remaining pieces of the ISC spoiler during a pitstop:

What's the opinion about the Garage Vary lip combined with this? Is the GV functional at all? Combined with a splitter?

Looks like 2.5" risers. I'll have the same thing in a week.

It looks like the wing is mounted to the rear quarter panel through the gap in the trunk lid.

Also, How do you measure the angle of attack w/ 3d wing like these?

You just measure in the middle. They produce significant downforce at 0 degrees of attack.

Sav, thanks for sharing all this info. Its just what i needed to convince me to pick up a wing.

Now to see if it'll fit an NB. I measured my trunk lid as 40.75" is that the same as the NA's?

I hate wings, but that one looks good, and most look good on a miata just because I know the there is reason. Small light car + rear wheel drive = downforce.

My miata is a little ways away from worrying about wings and etc. I've always been a big believer of aerodynamics. I read up a lot of formula one aerodynamic progression and there are some cool pages here: Browser Warning
That is just one article, look around and you'll find much more. Its nice to see someone do some sort of study. They show you how if you build a proper underbody to the car, you can actually direct more air through the engine bay without adding scoops by controlling the low and high pressure areas.

Cool stuff, I'll definitely be fabbing a underbody lip and spoiler for mine when I get more pressing steps done.

I'd rock that on the streets anyway...You have a race car, not a rice car..There is a difference even if the average joe doesnt see it.

I like the mounts, but I don't see them or the miata specific wing listed at SlickAuto.net Any information on whether or not they will sell the mounts alone? Two questions are 1) what is the mounting width and 2) are they adaptable to use with the GT-II base stands?

Thank you. I did it myself in about 12 hrs...all with vinyl.

The OGK is about 5 sec faster than the fastest Spec Miatas but it didn't run that day. Going CW (the other direction) without aero, it's done a 1:25.8 in much warmer weather. CCW is about .75 faster so I'm pretty comfortable estimating a mid to high 1:24 CCW.

The car that did the 1:25.5 in last Sunday's Miata Challenge was bellwilliam's NB with a non-intercooled Kraftwerks Rotrex Supercharger we installed the night before.

I have an ISC on the OGK and ran it without a wing for two events. Car was beautifully balanced before the ISC, a tad loose with it but not undriveably so. Adding a dual aluminum element APR wing with oversize carbon end plates made it push pretty much everywhere. That was running it at 0°. Running it at about 4-5° allowed me to go through Riverside at Buttonwillow at a little over 90mph... in the rain.

So what I discovered is that the wing is making a bunch more downforce than the ISC. Pretty much all the fast Miata track guys with wings are planning major front downforce to keep up with the wing. Like Savington said, just slapping canards on it is not necessarily the most efficient and the Miata is already a brick. We plan on doing something for MC #3 but it's tOp seKrit.
