Thank you for helping folks out! You should be able to replicate the issue just by driving close to a wall and watching when the wheel starts to jitter between the ground and the wall. The more negative the angle is compared to the sphere, the worse the jitter becomes.
Also, turning your car upside down reveals the issue really fast. Even placing a cube above the tire will cause the system to ‘suck’ the tire in. In my example of being upside down, the sphere sucks the tire into the ground, completely bottoming out the suspension. This happens even when the sphere is much smaller than the wheel (the attached picture shows the wheel penetrating the ground).
This makes the system unusable for things like rough terrain—where it should actually shine—because the suspension literally grabs and pulls toward anything it sees instead of just supporting the vehicle’s weight
Edit: I remember seeing this being mentioned before and here is another good example of the issue some one posted few years ago Chaos Vehicle: Wheel Detecting Ground Upside down? - Programming & Scripting / Blueprint - Epic Developer Community Forums
