. operated more like a flap instead of fixed angle rear wing would it help prevent the cars from getting airborne when the cars spin backwards?. Example: If the car spins backwards then the angle of wing would operate like a flap and flip toward the front when the car spins backwards thus creating downforce on the rear at high speed tracks. If the car spins foward again the wing angle would again flip back toward the back again in the norman position Just wanted some input on what effect people thought this would have on the car.
The current “wing” does not cause lift forward or backward. When the car spins backwards the air is forced under the wing over the back roofline and keeps the car down. Also, the cars still have roof flaps. Some of the earlier versions didn’t that were being tested on the short tracks (just to save time in fabrication) and it was thought that they did away with them, but they didn’t. There is still the issue of side draft causing lift, but the increased height of the roofline and the blockier profile of the car has helped to keep the car on it‘s wheels in a spin. The side skirts (keeping air from under the car) are more even on the COT because the front end is not traveling as much (causing them to cut them down) so that should help as well.
im sure that if possible they wld.but if possible.
That's a good idea, but the violent flipping motion of all that surface area would probably cause too much shock on it's components and rip it off, or make it unstable when it was returned to it's normal position, and not setting it at it's correct angle.

I am sure Nascar tested the wing in the wind tunnel backwards to be sure it wouldn't have excessive lift when they were developing the COT. A wing cross section is teardrop shaped, rounded at the front and pointed at the rear so it does not produce as much lift or downforce when reversed. The wickerbill also disrupts the air flow over the air foil when reversed. If you dropped the back of the wing all the way down until the wickerbill was on the deck lid it could work as a reversed spoiler giving downforce when sliding backwards. I don't see any way that you could accomplish that with out some sort of electronic sensor and actuators which would be way complicated. Have any of the new cars lifted in a reverse spin?
