Why is there a discontinuity in the tire force that appears only when the brake torque is nonzero? I’m still investigating, but it looks like we’ll need to redesign the final stage of the wheel model.

The 424 made it to the front page of this month’s RACE TECH Magazine! A six-page feature by RaceTechmag covers the car’s development, designed using a simulator powered by Vehicle Physics Pro, turned into a full engineering tool.
I couldn’t be prouder to be a core part of this project 🤩

Here are eight views of the same wheel model under different conditions. Everything looks nominal except for the longitudinal force when the wheel transitions from freely rolling (slip = 0) to fully braked.
