If you're turning left, you want the left wing to incline so that it produces more downforce. Same logic for a right turn, with the right side going up. This will help counter body roll, and also produce a force on the inside tires of the vehicle to increase available traction and therefore cornering speed/stability.
the wing would operate in opposite to increase downforce on the outside tire and theoretically decrease the force on the inside tire. but seeing as the trunk lid connects in the center where it locks but im sure the deck lid presses onto the body
I guess I don't understand how suspension and handling and all that works. I would have thought that you would want all 4 tires providing maximum traction in corners. You are saying that because of weight transfer forcing the outside tire to carry more weight and the inside to carry less, you are trying to reduce downforce on the outside tire and increase downforce on the inside? This does not make sense to me. Downforce is effective regardless of the cars momentum, That is why you use downforce instead of bricks in the trunk. I would think you would want maximum downforce on both rear tires to give them maximum traction to counter the car's momentum trying to make it go straight. As for eliminating body roll... shouldn't you tune the suspension to do this?
Anyways, I don't understand it, it is beyond my brainpower, but it is a cool gizmo. I look forward to the finished product.
Tuning suspension is obviously very important for racing, but sometimes theres only so much mechanical grip available. Plus, if you only use suspension to counter body roll, you may have a suspension that is much too stiff and unforgiving. Using aerodynamic force to counter body roll gives you the best of both worlds. Also, giving the inside tires a little more downforce gives them more traction. The ratio between the two is now more balanced rather than increasing downforce on both the inside and outside. Since the outside would have already had more normal force on them from cornering, the tire contact patch is deformed and decreased. By balancing the forces, the contact area would be ideally increased.
Thanks, I obviously can't take credit for the camera work, I'm the one driving. That was one of my buddies at school. More pics and videos to come (check the build thread too)
I apologize for the weird sounding audio. Something happened to it when I uploaded it to youtube? I don't want to do an "audioswap" otherwise you won't be able to hear the car...
i just hit play/record on both the vid and audio. some areas lined up almost spot on shot with a GoPro SD action camera.....
i just found the video editor so i will get better the more i play with it. Mera driving season3 only started yesterday, after all so theres plenty of time.

Just a quick drive today, just got her out of storage and needs a wash still. Snow coming this Saturday so maybe another week or two before some more driving.

Thats my buddy's car. Its an 82 and in really good shape. I also know 2 other guys with MKII supras. Not common to see around here. Somehow I know three people with them lol.

Enjoy!
I like.
Do you think this thing would improve 1/4 mile performance, gas milage?

It would only improve 1/4 mile performance if you were having trouble with traction at high speeds. As for gas mileage, it would only improve it if it replaced a wing that was on the car that produced more drag than this one, OR if you were to angle this wing to produce lift (this would also result in high speed instability. Not good)
This was designed to be for more of a road racing application. Hope that helps!

Street Tire Street Modified (TSM) - only I'm missing the T. I read through the scca class rules, and it looks like with an engine swap, your pretty much stuck in street modified. I got 4th in my class of 9 though, and was only half a second off from 2nd place.
Just found the high res version and updated my first post.
