Threshold braking analysis theory

Compare peaks in longitudinal acceleration around the lap to find opportunities in your drivers threshold braking analysis.


  • Flat track
  • Uniform grip
  • Consistent car

Image below shows opportunities for investigation at points 1, 2, 5, 6 & 7.

How hills affect braking long acc peak accessment

What to look for / be careful of?

  • Does not really work for fast corners –> can unsettle car.
  • Hills –> consider correcting analysis
  • Changing track surfaces
  • Driver inputs
  • Tyre temps
  • Friction circle
