Here is the wheels magnetic linking to body.
Where is the optimised way to achieve this?

 

Hello, there.
I could maybe help you with this one, but your GIF link doesn't work.
Could you perhaps sent it as a file?
Regards.

Well, it depends on physics behaviour of the objects. Unity gives you these options to link objects togehter:

1. If the two objects are rigidbodies, you can connect them with a joint component.
2. Make the one object a child of the other object.
3. The one object could follow the transform of the other object with a script running every frame.
