Contact Patch Longitudinal Compliance – Suspension KPI

Contact patch longitudinal compliance (or its inverse, contact patch longitudinal stiffness) is a metric which measures the deflection of the tyre contact patch to a longitudinal braking force.  The metric is reported in millimetres of suspension deflection per Kilo-Newton of braking force, mm/kN.

Contact patch longitudinal compliance is a metric used to understand the compliance in a suspension system under braking.

RACE reports both contact patch longitudinal compliance (mm/kN) and contact patch longitudinal stiffness (kN/mm).

This KPI page is only a brief overview. To learn more about this and other KPIs, including KPI values used in industry, real-world examples and best-practice guidance, please refer to our courses below.
