some beautiful footage from the IMSA 12h at Sebring, a track renowned for its challenging bumps.

This footage isn’t just a treat for the eyes; it’s a practical lesson in vehicle dynamics!

One of the things to observe is a great demonstration of the vehicle showing itself to be an an over-constrained system. With four wheels, it has one more than necessary to manage its six degrees of freedom and maintain equilibrium.

Consequently, a bump affecting the vertical load at one wheel directly impacts the other three, creating a complex interplay of forces that influence the vehicle’s state.

This behaviour can be fine-tuned through adjustments to spring stiffness and damping rates.

Beyond sensor data, observing these dynamics in action really offers some profound insights into performance,

Reminding us that sometimes, our own eyes are the best tools for understanding the principles of vehicle dynamics. Don’t neglect them!
