That was McBeath's Competition Car Aerodynamics, right? (Just in case anybody else wonders which book....)
About $30 from Amazon.

First off, a disclaimer: I am not an Aeronautical Engineer! Some of you guys are far smarter than me when it comes to aerodynamics. With that said...
The 3D wings are still effective below the roof lines. The APR wing data is a CFD model, so it will tell us something, and they are doing their due dilligence. They don't have the budget to do wind tunnel testing on every application.
However, we've used this wing and did some of the testing on the final production peice, and it WORKS. Buttonwillow is a great track to test aero on with the high speed corners. The car will stay planted through Riverside.
Per APR's recommendation, run the wing between 0-10 deg AOA. Right now we have ours set to ~5 deg.
We are running the 1/2 height wing bases. APR also has full height wing bases. Another bonus is that the OEM rain channel will still function. So if you remove the wing for DD use, water will not run into your trunk if it rains.
Also if you are running a big ass wing on the middle of the trunk, you can deform your trunk lid. With the mounting bases being near the edges of the trunk, you don't have to reinforce the trunk.
Here's what the S2000 Specific wing looks like.
Compared to the universal.

... yes it makes sense...
Apparently the generic APR 200 wing does NOT have the mounting points to fit the S2000 trunk without binging the trunk. I have been in contact with APR and the rep has stated that a fitment and wing have been produced for the S2000 exclusively.
The photo of the white S is the new fitment. The latter silverstone is exactly what I have on my S. The new fitment is higher and is a cleaner install.
