Hey guys. I apologize for not keeping up to date. Been real busy answering the pm's.
There comes a point for every business where the "yes" answers turn into "no's." What really makes the project time consuming is sourcing the original parts and making the molds. Once the molds are done, we can make the part whenever we want. That would be ideal. However, we have soo many projects on the list right now, I simply just have to start turning projects down. There's too much pressure to finish all these projects at one time.
we have a low profile spoiler for the FD in our possession, which most of you probably know. There is a ton of demand and still we can't get to it even though it's not a difficult project.
Since the demand for this wing is low, there is one solution. I know of the company that Chuck uses to produce these parts. They are located in southern california. The owner of the company is extremely hard to get a hold of and is somewhat stubborn.
If the mold is still good and I can pull off a deal with him, that would be great.
Carbonfiber is backed by fiberglass to give adequate strength. The CF layer alone is not enough. Backing CF with CF is most of the time overkill and will drive up the cost.
Also.. we've never made a GT wing before so our experience is very limited. At the same time, I'm pretty confident we can pull it off.

If you transfer a wing from one car to another it will still produce downforce, but a application-specific wing will always be better. If you mount it on a different car all that research that serves as a selling point suddenly loses a great deal of its value.

Honestly are you Fu888ing kidding me?
Ken isn't Aerodyne Composites.
What do you mean especially a GT wing, all wings have different applications and you don't see GT wings being used on 400 km.h Lemans cars do you give us a break.
I think you will find that all wings like RE-A are the same kind of design with different widths and angles thats it. So application specific isn't that important.

Dradon has a point. RE-A designed this wing for the FD and it has been race tested but dont think that the same process went into this wing as a F-16. The plane of the wing is designed for downforce period. It is the pilars and placement that is, for the most part, car specific. Look at the APR GT wings. They are "universal" but they arent Pep Boys knock offs either.

And the F-16 wing is designed for lift period.
I never said the wing wouldn't work, but you don't need a windtunnel or full CFD to make a wing that "works" or even "works pretty well."
Anyone with some knowledge of aerodynamics can pick a highly cambered NACA airfoil, add endplates, and mount it on a car. That would be quite functional and work.
There are simple tools out there for free that will take an airfoil of the designers choice, provide airfoil data, and calculate the flow around a wing with those airfoils...then provide lift and drag data for any angle or speed you ask. This lets you optimize airfoils and wing planform in free stream, and makes something that works pretty well.
The real value of the windtunnel is that you can look at how the air flows around the car, and design the wing around that specific vehicle. You can then do things like increase the angle of attack at the tips to make up for the fact that air flows upwards around the fenders and hatch (*gasp* that's where the GT shape comes from), or move it to an optimum location to balance clean air to the wing versus airflow pulled from under the car. Then you get a wing shape that is really optimized for one specific vehicle....great.
But if you want to sell it as a windtunnel and race tested solution for anything besides that vehicle you would be lying....because it's not. It's just a curvy wing with a good airfoil.

Also, APR is one of ~2 companies that produce SCCA approved wings. Lots of track cars run them with good results. All of their designs are "universal" with different stands for different cars. I trust track results more than simulations and windtunnels where braking and crosswinds play a part.

su_maverick just pointed me to this thread so here it is... GB interest thread for a GT wing. All the details are in the thread. Since it looks like this RE-A GT wing isn't going to see production anytime soon, it might be a good option. Hopefully Ken doesn't mind that I'm posting this here.

Definitely less square inches of surface on that model. That means less downforce. I'll wait and see what comes up or give up and go to Corksport for the real RE wing. Perhaps Corksport could arrange a group buy??? I think they list it at $1050.

1600mm CF version is available, although I still need to find out the price(shouldn't be more than $1000). The pics show 1450mm version. Anyway, I don't want to clutter up this thread so please direct any questions or comments about the wing I posted to my thread.

for what it's worth. . . Ken, i'm flying out for 7stock, if you want me to nab my RE-Amemiya wing to help the homies, let me know. Just ship it back to me when your done (if there's enough interest for you to make it). I'd need to know by 9/10 as i'll be on the road after that until 7stock.
Ciao~

that makes 9 and i know there are more people in this GB (the gt-wing) that are interested as well, why dont we merge and get something going here???

Two competing businesses forget about it. People make their own choices with whom to go with. Personally, I got my bodykit from Shine Auto and it fit better than any of the other kits my bodyman had installed on FD's, I think he has done 4 or 5 FDs.
If two competing businesses make the same part, I know personally myself I will always stick with a business I have done business with before.
If I was to buy a wing it would have to be the GT-II Normal height wing and the mounts would have to be exactly the same of the Amemiya one the most annoying things about other so called "GT or 3D" Style wings I find (this may be true only for me) is that the supports of mounts look to bulk and just ruin the sleek look of our cars.
