I'm looking for a custom adjustable wing, but I don't want something that has high drag. I know with any additional aero pieces that provide downforce you will also get drag as well, but after looking at some of the 'off the shelf' wings available I noticed that few have an actual airfoil profile. I am looking for something that is function over looks. I would ideally like an adjustable airfoil piece that can increase the downforce on the rear of the vehicle, but not greatly increase the drag. adjustabilit is key here as I tend to 'play' with things a lot at the track to find the best setup. I have thought about making my own, but wanted to ask around first because buying is usually just as expensive as making something yourself (once you buy everythign you need to make it). I've don some searches, but nothing has really come up.

Thanks!

 

I went with an APR GT250 for the same reason. It's just a plain airfoil so it's hard to mess up, really. I've been meaning to scan in the cross section and figure out what NACA profile they used. They are adjustable, but I built a taller mount to ensure its in clean air.

 

if you are looking for something different, contact Stohr cars. They build WF1 and F1000 SCCA road race cars from the ground up.

The "3D" wings like the APR 200 and 300 are shaped like that to prevent the middle section from stalling due to the angle of airflow over the roof of the car. The idea is to maintain constant angle of attack relative to the flow of the air across the wing. 2D wings like the 250 are fine, but you need to run them really high in order to avoid stalling the middle of the wing. So if you're going to run it really high, a 2D wing is a good bet, and if it will be lower than the roofline, you might actually get better performance from a "cool-looking" 3D wing.

 

I wasn't thinking about that, good info, thanks. I have been reading the STL rules and the APR 200 wing is specifically mentioned as being allowed for the S2000, so that is probably the one I will go with because it is adjustable, readily available, and per the rules the wing must be 4" below the highest point of the cab of the vehicle (so getting into 'clean' air is not reall possible).

Thanks for the info everyone!

 

The bad news is that the S2000 isn't allowed in STL.

Above is a link to the March 2014 GCR where it discusses the S2000 in STL. Allowed with the F20C motor, 2,890 lbs, and a 50mm restrictor. Maybe it wasn't allowed before, but it is now. AP2 S2000's are not allowed due to the 2.2L motor. Where are you getting that it isn't allowed? There is even a section where it lists vehicles specifically not allowed, the S2000 is not listed. Pretty sure they would list it there if it wasn't allowed, not to mention they give specific guidelines that ALLOW an s2000 to be run in STL.

As always, it is allowed in STU.
