Rocker and Sprung Mass Connection Nodes

Chapter: C10

In Simple Terms

Suspension parts connect to the car's rocker and main body at specific points that allow movement in only one direction. These connection points can only have sensors attached—no other devices are allowed. This keeps the suspension simple and ensures fair competition.

  • Suspension elements connect at designated nodes that permit rotation between parts
  • Connections function in parallel with single degree of freedom between end nodes
  • Only sensors are permitted at these connection points; no other functional devices allowed
  • No feedback devices can be connected to suspension elements
Official FIA Text
