Article C10.2.3
Suspension System Components
Chapter: C10
In Simple Terms
An F1 car's suspension system is split into two main parts: the outboard parts you can see (like the uprights, wheels, and bearings connected to the wheels) and the inboard parts hidden inside (the mechanical systems that allow the car to move up and down). Together, these components allow the car to stay connected to the track while absorbing bumps and maintaining control.
- Outboard suspension includes visible parts: uprights, wheel axles, bearings, fasteners, and wheels that directly connect to the tires
- Inboard suspension is the hidden mechanical arrangement inside the chassis that provides vertical travel and absorbs impacts from the track
- Both systems work together to keep the car stable and responsive while cornering and braking
Official FIA Text
Suspension comprises outboard suspension (uprights, attachments, wheel axles, bearings, fasteners, wheels) and inboard suspension (mechanical arrangement providing vertical travel response).
