Which component is typically improved to boost a vehicle's handling?

The suspension system plays a critical role in a vehicle's handling characteristics. By improving the suspension, you enhance the vehicle's ability to absorb bumps, maintain tire contact with the road, and reduce body roll during cornering. Upgrading components such as shocks, struts, springs, and sway bars can significantly improve ride quality and handling precision. A well-tuned suspension allows for better feedback to the driver, increased stability, and improved cornering performance, which are essential for high-performance driving and optimal safety.

Other components, such as windshield wipers, interior upholstery, and headlights, while important for various aspects of vehicle functionality and comfort, do not directly influence handling dynamics. Instead, they focus on visibility, aesthetics, and convenience, which are not related to the responsiveness and control of the vehicle during driving maneuvers.
