What does excessive body roll during cornering indicate?

Excessive body roll during cornering indicates that there is inadequate lateral stability in the vehicle's suspension system, primarily due to the sway bars, also known as anti-roll bars, not performing effectively. Sway bars are designed to minimize body roll by linking the left and right wheels, thus distributing the weight more evenly during turns. If the sway bars are worn out, they won't effectively counteract the lateral forces acting on the car, causing the body to roll excessively when cornering.

This condition can lead to poor handling and increased risk of losing control, as the car may feel unstable or overly loose during turns. The sway bars play a crucial role in maintaining vehicle stability, especially in performance driving and sharp turns, making their condition vital for safe handling.

While overinflated tires and other factors can affect vehicle dynamics, they would typically not result in prominent body roll characterized by the sway bar's function. Additionally, increased engine power generally influences acceleration rather than body roll, and improper brake function would affect stopping ability rather than cornering stability. Thus, recognizing the importance of sway bars helps diagnose handling issues effectively.
