Aftermarket Rear Wing "Results"?, especially active / aeromotive Options

[35R]

For those who have replaced their factory (rear) wing, were you able to attribute a real improvement on the track? What did you go with and why? Did you need any complimentary setup (like tending to the front downforce too for example). Also, anyone tried the active wing, and do you think it is worth it over a fixed one?

cheers!

couple of time attack teams running the Aeromotions wing (GTR's, Evo's and STi's) Obviously these are examples of full bred sprint machines with one goal in mind. You can look at aeromotion's site as well as APR's site for more info on active aero and aerodynamics in general. I guess it comes down to how far do you want to go with this car and what you want to achieve?

Forged has had great track success and to my knowledge he is still running a stock rear wing. (Of course he is running JRZ's and a couple other tricks for suspension and handling, and a great driver). AMS has set track records with their Evo and they are sporting an AM rear wing and again, adjustable suspension, great drivers).

Darrin was the first to have an AM wing for the GTR so he might be one to speak with along with Sharif @ forged.

Just my .02

thanks for the response. Anyone with hard data or even something vague, like how manu seconds you improved etc.?

[HKYStormFront]

i can't speak for Sharif but he recently switched from the stock wing to an Aeromotions wing and said he could feel a vast improvement from what i remember. i'll let him chime in when he see's this thread with more info

Go active all the way. Greg at Aeromotions has a couple versions available now so it's not cost prohibitive at all. In general the tracks we have been on are around 2 minute laps and the wing in an active mode shaves 1.5 to 2 seconds off each lap.

Sharif runs an AM wing but has not gone active with it (you can install then upgrade to active later if you want). AMS Evo, Crawford, Fontana Nissan all run a variant of Aeromotions in Red Line.

There just isn't a static angle wing that can compare to something active.

Funny story Tarzan ran the Crawford car a couple laps before their engine blew, first lap was active and second lap he turned it off and slid off the track.

My Aeromotions S2 active wing goes on in about a week.. I havent tracked the car year, but i've driven her pretty hard on the streets at times so, I will tell you what i notice after i put it on, but i will have no data of before and after as far as track times. Shariff is running the S2 wing as well, i thought he was active, but i might be wrong.

thanks for the feedback guys. Any thought on the split wing vs the single?

For those in competitions, amateur or otherwise, do your regulations allow active wings?

[underpressure]

S wing is worth a couple tenths over the R wing.

Most organizations here don't have rules against active aero.

Hi, this is Greg from Aeromotions. I love it when people ask for data

Sharif @ Forged is currently tearing it up with the Static R2. His record setting lap time of 2:00.002 at VIR speaks for itself. Here's his comparison replacing the stock wing with a Static R2.

Went from a 1:20.25 to a 1:18.7 with no other changes, and very similar track conditions.
Overstear at medium to high speeds completely gone.
Track name is Roebling Road in Savannah, GA area.

You usually get another 1-1.5 seconds going active. Last year, we tested Kunani's GT-R with the S2 in static and active mode. Sending it active shaved about 1.29 seconds off a two minute lap. That's on top of the gain from having the static wing in the first place.

Derek has repeated the Kunani experiment with the same time saving / results.

And, no post would be complete without thanking Will for setting a new wet skid pad record at the Tire Rack (.953G with an R2.2) and winning one lap.

A big thanks to all you guys for doing so well. It's been a fun year.

My GT-R was transformed with the wing. I dropped 1.5 seconds on a 1:20 course at Roebling Road, and the difference in feel is immediately noticable. I could transition to full power earlier at corner exit, and the high speed oversteer I had been fighting was completely gone. I am running the static wing for now. I imagine the active will add another few tenths of a second at least.

This wing is one of the few, that has some serious science and research behind it.

[35R]

ok this sounds promising. With the static wing, how much work have you done to tune the angle? I suppose it depends on the track too. Sorry but i've never used an aftermarket wing. Can you guys explain something for me... the active wing flattens out on acceleration and adjusts for braking and turning. What happens if you have a high speed turn, not necessarily high g's?

Say turn 1 here

You might be accelerating on the apex (somewhere between 100 to 120mph) and it's not necessarily high g's - it's quite long and flowing. What would the active wing do for this turn?

That is a great question and one that I would love to have answered as well.

One reason I am a bit afraid of using the active wing is the fact that it responds to g-forces, but cannot predict them. Very high speed turns, like the final sweeper at Willow Springs Raceway for example, require a very settled chassis and lots of downforce. I would be nervous turning in for that turn wide open throttle with very little rear downforce.

Some way of mapping the track and having the wing predict when you needed downforce would be VERY cool. Other than that I would probably just put a two position switch on my steering wheel and adjust it manually.

Pretty sure there is an in cabin remote on the AM wings that you can use to up the wing angle in car.

Good question. The R2 wing has 3 angles, Braking, maneuvering, and straightaway.

The wing is nominally in the maneuvering angle. In that turn, it would be in maneuvering no matter how hard you accelerate, or corner. The maneuvering angle is set to where the car is neutral in a turn. For the GTR, that's about 150lbs df @ 100mph.

If you brake hard, the wing will increase downforce and drag by going into the braking angle.

The only time the wing will drop is if you're over the straightaway speed (factory set to 90mph but you can easily change), AND have no lateral acceleration. If you start to corner, the wing comes right back up. We have active wings running on quite a few GTR's. None has had a problem. However, if you're not comfortable with the wing dropping into straightaway, you can easily turn that feature off

We've also considered GPS based wing movement. The main problem is that GPS is flaky. My background is autonomous helicopters running on inertial navigation systems. We ran mill spec GPS units. Sometimes they would crap out on foggy / rainy days. The key to active wings is ALWAYS doing the same thing, every time. I can't guarantee that to 99.999% certainty with affordable GPS based positioning. With the inertial package, we can. BTW, if we got fancy enough with the GPS to guarantee it, no one could afford it . . . .

The in cabin remote can be used to change each wing angle, or to override the computer control. If you want a manually controlled wing, we'll sell you one

Looking forward to installing my active S2 ... Greg is the man when it comes to this stuff, he drove down here to new york to visit me and go over everything while i did a photoshoot of the porche he just completed a wing setup on.. Wing looked incredible and installs are super clean. Quality is top notch.

I think we would all like to see some pics of different GTRs with their wings. Some people would think the GTR with the wing on looks ricey but for me it looks awesome. It is one thing when a Honda Civic has a wing but a whole other when it is on a car like the GTR. The word Race and Supercar comes to my mind. Also, when you take the OEM wing off, isn't their three holes in the trunk? When you mount the static, do you have to fill the hole located in the center of the trunk?

check out this video!!

Just put this up, its my car with split S2 and Fontana Nissan's Redline Time Attack GTR with the R2:

Also thesimones, doesn't matter what people think, it works and looks great. My car gets mad attention everywhere and a big part of it is the wing. Also note Aeromotions made custom end plates to mate the shape of the rear quarters (swords edge) design. I was also the first one and paid the dev price to get my wing at the lowest effective height so it didnt look like I had a huge GT wing standing on the back of my car. This is the result!

[AutoXGTR]

Looks great.

For those in competition, best to check the rules carefully about use of active wings.
