I just upgraded my Unity 6 preview project from version 6000.0.9f1 to 6000.0.20f1 and noticed that the wheel colliders seem to behave differently and would like to know if it is a bug or something I am doing wrong. When I run my project the wheel colliders are lower than the should be

And as soon as I change any value in any of the wheel colliders they all seem to fix themselves

I tried replacing them with new wheel colliders in my project but that didn’t seem to fix the issues. My wheel colliders are using the default values from when you add a wheel collider except for the spring length is a little shorted (0.3).

Is this a bug? Should I roll back until this is fixed?

Hi can confirm the bug by starting a new project in Unity 6.

Moving the project back to 2022* and fixing the packages works correctly.

If you change ANY value in runtime the wheels goes to the correct position and everything works. So the issue is only when you start the game.

Did you create a bug report in Unity, because I was not able to create a reproduction project, but have the issue myself. If so, could you link the issuetracker so we can upvote it?
