Help with Raycast suspension

Hello, I don’t know that if this is the right spot but I would like to know where the heck can I find reading implementing a raycast car? I originally just mashed one together but it is sliding all over the place. So I kind of cheated a little and added drag to the rigid body when the thing was grounded. What I am trying to do is see if I can make vehicle movement physics similar to that of king of the road(old arcadish trucking game) for learning purposes. Now I am getting frustrated with google not showing me what I need. Be advised that I am not asking for kart physics I am asking for tutorials and information on how to go about car or heavy vehicle based semi believable arcade physics.

Thank you,

Thank you for the response. But I am trying to implement my own raycast car physics. I am asking for tutorials or readings not assets.

Not to be rude but your suggestion defeats the purpose of what I am asking for.

Never mind I figured it out. I decided to bite the bullet and stick with what I have.
