Working out the correct forward axis for Unity's wheel collider.

Unity Engine

Hello everyone.
I created a low poly car model for my racing game.

But when exporting it with those settings:

It looks like this in game:

The wheels start rotating sideways.

It’s probably because of the wheel colliders:

So I tried changing the forward transform in the blender export settings, I tried to rotate it in blender, all of this took me 13 hours.

Slowly all of the car stuff is getting on my nerves…

Can anyone help me with that? Thank you.
Have a nice day and stay healthy.
Regards

You need to check the “apply transform” box.

Wheel colliders are always aligned with Unity’s “forward” direction which is the positive Z axis.
