A racing car has a wide base for increased stability and cornering ability. The wider base helps the car to grip the track surface better, allowing for faster speeds and more control. The wider base also helps the car to distribute its weight more evenly, reducing the risk of the car spinning out of control. The wider base also gives the car aerodynamic benefits, helping to reduce drag and thus increase speed. Finally, the wider base helps to protect the driver in the event of a crash, as the impact is spread out over a larger area.
