I will be the first to say I am not an engineer. But the car has all the characteristics of a bullet when it gets spun at high speeds. It lifts off the ground and starts to spin instantaneously. There is nowhere on the car for air to take hold and slow it down. And I have my doubts that lowering its already streamlined profile even further by taking away one of the larger components of the car, the wing, will change that. And by NASCAR leaving it on for certain races for the rest of the year makes me believe they have the same doubts. To me, the rest of the schedule will play out like a testing session. And I dont think a final verdict will come out until after Homestead.
They put alot of time, energy, and money into developing the COT, and decided the wing was the way to go.
