Taco wings are heinous, and the GT3 taco adjusted for max downforce is just unforgivably ugly.
Leading evidence: 'Adjust max downforce is just unforgivably ugly' (no explicit attributable resolution; this is a reported action or suggestion).

Suggestion
Because my car is running 19" tires, the tire sidewalls are very short, and that plus a bouncy suspension resulted in the rear end being skittish when I first got the car with the wing in the neutral position.

The neutral setting may interrupt laminar flow but may not add any downforce.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I have an 02 coupe. I believe our stock popup spoiler just reduces lift but creates no downforce. Does anyone know of options that are street/track (i.e. not a huge wing) that can create some downforce or at least better reduction of lift than stock spoiler? I have just started my research and have briefly looked at some of the items on Getty, Mashaw, stuff on ebay, etc.
If you do have a particular wing/spoiler, what difference was felt on the track vs your stock setup (higher cornering speeds or stability, etc.).
Thanks.
The MKI GT3 wing - which is also the MKII aero wing - is adjustable. The neutral setting may interrupt laminar flow but may not add any downforce. To adjust the wing, you loosen the bolts at the top of the uprights and insert a shim. Porsche makes 4-degree shims and 8-degree shims.
I imagine you could also make your own custom shim if you wanted a more specific wing angle.
In high-speed driving (above 120MPH), I have found that the 8-degree shims make a significant difference in how the rear end of the car feels. I have also noticed a decrease in fuel economy with daily driving, but it has not been significant and I have not noticed any additional tire wear (the 911 isn't exactly easy on rear tires anyway, so I don't know that I'd be able to tell).
Since this wing was available on the GT3 MK1 996 as well as the Aerokit II, it's common enough for daily driving (i.e. it's not a massive metal-and-carbon contraption suitable only for the track).
This is a photo of my 996 with the 8-degree shims installed - you can see that the rake of the wing is significant.
Because my car is running 19" tires, the tire sidewalls are very short, and that plus a bouncy suspension resulted in the rear end being skittish when I first got the car with the wing in the neutral position. Adding the shims definitely helped make the rear end less jumpy at normal (highway) speeds.
The aero parts on my car are Porsche, not aftermarket. I believe they were sold as an "Aerokit Cup" kit for fitment on a MKI 996, but I have not run the part numbers to confirm this.
I think the GT3 look aero kit on yours is for a Mk2 GT3/gt3 look. The MK1 is the taco wing that was found on MK1 GT3 and GT3 look aero cars (like mine).
That is your opinion and you are certainly entitled to it. I like it because it is unique to Porsche and a signature mark, sorta like the turbo twist wheels, whereas the mk2 gt3 wing looks like a lot others out there and more plain jane. Different strokes for different folks...
[QUOTE=996_North;12378590]What Alpine said... plus MK2 GT3 wing looks like a plain serving tray and lacks character. Taco rules! It's da bomb.
Agreed,
The MK2 GT3 wing looks like a book shelf bolted to the rear of a 996. All it needs to be complete is a matching pair of bookends.
I think if you are going for max downforce (or negative lift) the RS spoiler is the most effective. Don't forget they are called "spoilers" as they spoil the flow of air across the rear and mimic an upside down wing.
There are a few threads including this one below that discussed the RS. Do a search in Google, there is not much quantifiable info though.
It might be safe to assume that the MK2 complete aero is a more advanced than the MK1, and have more downforce. Keep in mind the front and sides need the aero bits as well. Just a spoiler will be unbalanced.

Both are negligible unless you're going well past 100mph but for max rear downforce, you'll want a cup car rear wing as it has a larger surface area but more importantly, elevated above the roof level where they function more effectively.
As for mk2 being more "advanced" in aerodynamics, lol, I don't feel like participating in a oil/tire type debate.
If you wanna "one up" the mk2 picnic table, you can always do the quasi-race mode mod on your taco. Lol
But I have scientific proof that the taco looks better. I have summarized this data in a pie chart to better summarize all the data and the through research,
It would be better if you could use "summarize" - or various permutations thereof - at least twice more in your clever post...this would thoroughly evidence your "throughness."
Oh...and...
As much as I enjoy a good shrimp or mahi taco for lunch, on my car I prefer the Mk II wing - I can use it to iron shirts when I'm not out astounding folks at the track.
Nice job painting the shims. I'm not entirely sure why Porsche decided to make them bright orange instead of something a bit more subtle...like, say, black...
The 8-degree shims are the only things currently PlastiDipped on my car, and I plan to keep it that way...
Ah, the lone voice of sanity in a sea of crazy...
I find all these humorous... except the one about the Canadian Navy. You should do some research on that and what we have sacrificed. That one is pretty ignorant.
Oh, and when people start picking on spelling and then drag it down to the fact I am Canadian....I know I have won.. taco rules!!!! Woo hoo.
I don't think I am helping the OP out here so I'll stop the banter...
It's incredibly disrespectful to make fun of any branch of the military. It's disrespectful to objectify women, mock elderly Porsche drivers from PA for wearing "heavy gold," and it's certainly disrespectful to mock aged 996 owners who insist that the 996 is better than a 993/blow job/free liquor hybrid.

In order to assuage any hurt sphincters, the offensive image has been supplemented with a different but hopefully more offensive image:
If you track you car, and you choose a higher GT3 style wing, the front aero bumper/splitter becomes mandatory even at below 100mph speeds. There is a reason Porsche recommends fitting both or neither.
I would go with the MKII wing for sure. Adjustable and looks better than the taco. The taco wing just never seemed to look right... and it always made me hungry.
