I don't think the main problem here is lift, but Drag.

The Chevelle (however beautiful it is) is not the most aerodynamic shape to come out of Detroit.

1. the front bumper being angled downward provides lift.

2. The entire grill and head light area being nearly flat creates drag, and a lot of it.

3. the entire underbody is drag.

4. The hood creates downforce.

5. The windshield creates drag.

The problem of flipping occurs more with cars with smooth underbodies that are close to the ground, with too soft suspension. As they hit a dip or bump, the car bottoms out and loses all the downforce created by the smooth underbody and if the front is any higher than the rear at any point, at high speed the amount of air that gets rammed under the car will lift it.

The problem is not Flipping at 200 mph, but being controllable at 200 mph. There are supercars that are scary to drive over 150. Then again there are high powered sedans that will cruise at 180 like they are doing 100.

Here is the thing, do you want to do 200 mph once and survive and be able to say "I built a car that did 200 mph" or do you want to build a car that can do 200 mph comfortably without scaring the hell out of you?

Honestly, at 200 mph with a full cage you might not make it if you hit a bump. At 200 mph with a full tube chassis and the proper safety equipment you still might not make it if you hit a dip. Chances are you will if you have the right ssafety euipment, but there is also a chance you might not. I am not saying you will flip, but if the car is unstable at speed, it will be uncontrollable. Also, the road you might know very well now, will make your car behave VERY differently at 200 mph. Plus any type of lane change if not done extremely gradually (about 6-10 seconds) will be fatal. Think about how far you will travel in 6 seconds at 200 mph.

180 mph is like the sound barrier for cars. It is mysterious, it changes things.

If it was no big deal, we wouldn't have speed limits. There is a reason people are telling you it is crazy, it is extremely dangerous. It's a route people have taken before and not come back from.

Why are people telling you to work on the aerodynamics of the car? To make it more stable and controllable. So you will be able to predict how the car will behave and you will come back.
