lol without quoting everyone else, you have to think about other factors that make a car turn. Here's a question, how many tires steer the car? The answer is all 4.
Many things such as elevation, weight distribution of the car, the COG (center of gravity), brake bias, Limitied slip differentials, drivetrain layout like front engine powering rear wheels, or mid engine powering rear wheels.
Then there are the variables of the car in motion, such as how it transfers weight, braking, slip angles, tire sidewall deflection, chassis binding due to oversteer, etc.
It is a lot more complicated then just the steering settings of the front tires. In a street car, we are used to turning the wheel all the way, for things like u-turns, but in formula or le-mans cars, the steering ratio is dropped do to the time it takes to rotate the wheel. The one I drove is the Star Mazda Formula 2's, the steering never exceeded more then the 150 degrees from 0 being located in the 12 oclock position.
This is me in Turn 11, infineon raceway, in the F2000, you can see, the tires are not turned much even though it is a 185 degree u-turn with a radius of approximately 200 feet.
This is me in the same turn, bat in a TRC training car, which had stock production tires. Even with those, the wheel is turned a little more then shown above, but it never exceeded more then 150 degrees in either direction from the 12 oclock spot.
