Do F-body's make downforce?

Could you provide a more complete explanation of why it is accurate then? I don't really see it. You were correct on the pressure part, just the velocity/distance thing I'm talking about.
not sure I understand you. care to elaborate?
All I'm saying is, the distance the air travels over the top vs the bottom has very little to do with lift being generated, otherwise you would still see a lot of lift at zero angle of attack, but that is not the case. It is the air being deflected (thereby causing a lower velocity and higher pressure along the bottom) that generates the lift.

I wont argue with anyones explanations on lift theory since im ignorant to the subject my self.
Reguardless of the correct scientific explanation of how lift is achieved there is a significant amount of lift created over the rear of our cars at extreme speeds... this cannot be argued. 98% of the cars on this site will never reach those speeds or be able to sustain those speeds for any period of time.

Not sure how you drive relative to the angle of attack, but my car leads with the nose, so the air comes straight at the nose, kind of takes the angle of attack out of the equation.

when is the last time you went 180. whens the last time you went 180 and made ANY turn? i wouldnt try it, but you let me know how that goes, if you can control your car with all the sweat on your palms. and yes f1 cars are sweet and turn. but thats not even remotely close to a real car. if someone wanted, they could take a nascar car and put the interior back in.
edit: and seat 5.

And I've been well over 160 in my car, and over 170 on a bike so I dont think the "sweat on my palms" would prevent me from driving some nascar.

Reallly? I'de like you to show me the interior that came out of them...and no I dont think ANY type of unmoddified interior could be put into a nascar.
And I've been well over 160 in my car, and over 170 on a bike so I dont think the "sweat on my palms" would prevent me from driving some nascar.

Anyway we're probably not going to agree much. I reiterate my understanding that if you go fast enough (250?,350?) in a car with no downforce added, the car will lift off the ground, likely the rear before the front, not for weight distribution, but for aerodynamics.
Ok, now you can say I'm wrong and explain why by saying something that doesn't point out why I'm wrong again
