Conventional sprung suspension is used in Formula 1 cars. Any system which can alter the geometry of a moving car is not allowed. The suspension members are required to have a symmetrical profile for the majority of their length. This prevents designers from using them as aerodynamic devices. All car parts associated with steering system of the car must stand through an FIA impact test.
Suspension in Cars
The wheels in F1 cars should be tethered to body of the car with cables
fulfilling tensile strength requirements. The wheels are designed to
stop the wheels coming loose from the car in case of an accident. The
cars can be fitted with power steering systems. However, these should
not be electronically controlled. The suspension system must be arranged
in such a way that its response results only from changes in load
applied to the car wheels.
Components of Suspension System
When the car is in motion no changes are allowed in the suspension
system. Every suspension component must be symmetrical about its major
axis. No major axis of a cross section of a suspension member may
subtend an angle greater than permitted by FIA specifications. Each
wheel could be fitted with one or two cables, dependent upon their
performance at the time of testing. All parts fixed to the steering
wheel must be designed to minimize the risk of injury in the event of an
F1 steering wheel should be capable of standing through an FIA impact test. All components of steering system in Formula 1 cars should comply with the specifications of the FIA.
