Unlock Motion Ratio & Wheel Rate Analysis

Stop guessing spring rates. Motion ratio is the difference between vertical wheel movement and spring displacement, and it is essential when selecting coil rates .

With the Calculator, you can analyse how motion ratio changes as suspension moves, see red/amber/green scoring, and display wheel rate directly on the calculator canvas.

How to use it

  1. Open the Suspension Geometry Calculator
  2. Enable shocks and springs
  3. Click RC
  4. View the motion ratio score
  5. Enter spring rate in settings
  6. Tick Show suspension leverage overlay
  7. See wheel rate on canvas
