Threshold braking analysis theory

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

Assumptions:

Flat track
Uniform grip
Consistent car

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

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
