Notes On Anthropometry
There is amazing variability in human bodies. Generally, vehicles are designed to reach from the 5th to 95th percentile, including any gender differences. But determining the measurements to use is complicated. Different countries or regions may have different ranges, and the gene interactions for any individual result in many different percentiles depending on the measurement.
Brake Bias And Stability
The very best drivers can go up to but not over the maximum lateral capability during braking and corner entry. As they smoothly come off the brakes, the lateral limit increases due to both the friction circle, and more balanced loads front/rear.
Cockpit Control Forces
How robust do driver controls really need to be? Never underestimate the strength of a scared driver.

Introduction To Brake System Criteria
A highly optimized brake system properly managed by the driver allows longer wide-open throttle times, shorter brake zones, and higher average cornering speeds. This is how we reduce lap times.
