Problem with a car

Hi everybody.

I’ve made a car in Blender, import it to sweet Unity 3d xD, i add wheel collider, but when i press start my car always blown off xD WTF?

Should I merge all car parts without wheels?

It’s usually the center of gravity accessible through(rigidbody.centerOfMass) We should fake it by makin it a bit lower(negative value) in the y axis… hope this solves your problem…
