Skidpad g

If you have access to a skidpad, you can measure the number of gs that your vehicle will pull in a corner.

Skidpad radius     feet
Time per lap   seconds
g  

For example, if you can do 13-second laps on a 200-foot diameter skidpad, your vehicle is pulling .73 g.

This calculator uses the formula:

\[g = \frac{1.226 \times r}{t^2}\]

Where:

  • r is the skidpad radius
  • t is the time it takes for a lap of the skidpad
