This assumes that the body roll did not cause any problems by pulling the wheels out of alignment, which can have its own effects on a car’s balance.

This is particularly noticeable on cars that have very different suspension designs front and rear, such as most muscle cars with solid axle rear suspensions. The solid rear axle keeps both rear tires straight up and down, while the front tires will partly roll with the body. In this case, the body roll itself will cause the front tires to have less grip than the rear ones, and adding roll stiffness will reduce ...
