Experimenting With body and aero.

Thats not the concept. Its two pair of equally loaded tires (lefts vs rights) makes more traction.

I don't see that happening anywhere on a lap with the current cars. Least of all in the corner, where the most traction is needed.

We know that to utilize our stagger to most effect, the rear tires must be equally loaded. We want that to happen in the corner.
At that point, g forces are high, removing weight from the lf thru the center of gravity. At some point in the corner, the lf extends to the end of travel, ie tether. The most weight on the lf occurs at turn in.
Not seeing spoiler in the air counteracting all of that.

Would a dish style roof made out of sheet metal with like a 3/4 lip on the back help you or hurt you

Ask a winged sprint car

Air that goes over the roof does not reach the spoiler. Hopefully, that's hint enough...

My buddy said, many years ago, they found some slight downforce by putting a 1 1/2 " rounded strip (downward) on the back of the roof. Ive always done that since then, but dont know now if it helps.

Years ago, we had a convex roof, mounted level, it may have worked. Now, it's flat, mounted with 4" of rake and dynamically gains 5 more inches.

Something to try

At your next practice session or hot lap session and you want to truly see where the air is flowing on your car. Sprinkle baby powder on the hood, deck, roof, nose etc. Run two or three hot laps and come in. You can then see how the air affected the baby powder on your car, where the most downforce is due to the higher amount of powder being in certain locations. Its an easy and homemade real time wind tunnel. It really works.

I've been to a couple of notorius dust bowl tracks back in the day before there was an internet to complain on and the tracks never would keep the track moist because fans thought it was just a normal thing and they would show up week after week ... On these places the dust was so heavy that one could watch where the dust was going under the lights. the rear spoiler would kick a dust cloud up a few feet up before it spun in a rooster tail.
