WheelCollider and Material. Asphalt, Gum, Friction Problem

Unity Engine
1

Hi,
i have to create a car simulation and i want to give all the real values. so like:

  • Car → all the Physics and the right values from Datasheet (Size of the Car/Wheel, etc.)
  • World → Ground of Asphalt with the real value od 0.6 to 0.7
  • and so on.

So i have gave my Ground (Plane) a BoxCollider with a PhysicMaterial and the Values of 0.6 .
Now i want to give my Car the PhysicMaterial “Gum” withe Values of 0.9 to my Wheels. How/Witch Object i have to give the PhysicMaterial? WheelCollider or my Mesh with also a Collider with PhysicMaterial?
The WheelCollider provides also Material … what does it mean?

My meaning is, when i set all the Material and set the Mass and all of this values right, that the standart values of the Wheelcollider maybe the right, and the car drives like in the world. The Friction Values confuse me.

Thanks for listinig

The WheelCollider ignores the physic materials in the scene. The wheel friction is defined by the forward friction and sideways friction parameters only.

(scroll down to Wheel Friction Curves)

Not nice that the Collider ignore the physics. so how i can impelemnt this materials that the physics is function?
