Suspension State Definition and Restrictions

In Simple Terms

Each suspension system on a car must be controlled only by the position and movement of two rockers (mechanical arms that connect the wheels to the suspension). Teams cannot use advanced systems like automatic ride height adjusters, energy-storing devices, or computerized switches that would give their car an unfair advantage by responding to track conditions or braking.

• Suspension state must be defined solely by the angular position and velocity of two rockers per axle
• Advanced electronic or hydraulic systems like body acceleration sensors, inertial devices, and spool valves are strictly forbidden
• Ride height control systems and devices that store or transfer energy between suspension elements are prohibited
• Any coupling between suspension and other systems (braking, steering) or track event triggers is not allowed
