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).
Article C10.4.3
Permitted Suspension Elements
Chapter: C10
In Simple Terms
F1 cars can only use springs that get progressively stiffer as they compress, and dampers that passively absorb bumps without active electronic assistance. This keeps suspension systems mechanical and predictable rather than allowing teams to actively adjust them during races.
- Springs must have a monotonically increasing load relationship, meaning they get progressively stiffer with compression
- Dampers must be passive systems only, without active electronic control or adjustment
- Passive valves in dampers can respond to suspension movement, but cannot be actively controlled by the driver or team during the race
- This regulation prevents teams from using active suspension technology that could provide unfair advantages
Official FIA Text
Only permitted suspension elements are: Springs with monotonically increasing load relationship, and dampers conforming to passive damping specifications with passive valves providing damping change response.
Article 4H
Rear Upright Assembly (Excluding Axles, bearings, nuts & retention system)
Chapter: C10.6
In Simple Terms
The rear upright assembly is the structural component that connects the suspension to the rear wheel hub. It includes the upright itself, any brackets used for setup adjustments, fasteners, and electrical components—but excludes the actual axles, bearings, and nuts that hold it together. This regulation defines what parts are considered part of the upright for technical compliance purposes.
- Covers the upright structure between suspension connection points and wheel bearings
- Includes setup variant brackets that teams use to adjust car handling
- Encompasses fasteners and any local electrical/electronic components attached to the upright
- Excludes axles, bearings, nuts, and retention systems (covered separately)
Official FIA Text
Upright assembly between the connection to the suspension members and the wheel bearings. Upright, Brackets - including variants for set-up changes, Fasteners, local electrical and electronic components. Any braking system components described in Article 11
