Calculation Methodology

Roll Moment Arm (m) = (Center of Gravity Height - Roll Center Height) / 1000. Roll Torque (Nm) = Lateral Force * Moment Arm. Body Roll Angle (°) = Roll Torque / Total Suspension Roll Stiffness (Nm/deg).

Frequently Asked Questions

Lowering moves control arms into an upward angle, causing the kinematic Roll Center to plunge drastically faster than the Center of Gravity, lengthening the roll moment arm.
