Netcode Server Authoritative

Hi guys, I made a project with a car controller and I want to implement the multiplayer logic.

First I used the client Transform Networks and everything worked fine, but now I would to use an authorative Server.

In my script I have a function called Move:

    private void MovePlayer()
    {
        if (!IsOwner) return;
        GetInput();
        HandleMotor();
        HandleSteering();
        UpdateWheels();
}

    private void FixedUpdate()
    {
        if (IsOwner)
        {
            MovePlayer();
        } 
    }

I’m not sure about how to procede, initially I tried to use the clientRPC but in any case the client does not move.

Ok little update, I tried removing my script and using one based on the Character Controller and serverRPC and it actually works. This is a part of this script:

void Update()
    {
        if (IsClient && IsOwner)
        {
            ClientInput();
        }

        ClientMoveAndRotate();
    }

    private void ClientMoveAndRotate()
    {
        if (networkPositionDirection.Value != Vector3.zero)
        {
            characterController.SimpleMove(networkPositionDirection.Value);
        }
        if (networkRotationDirection.Value != Vector3.zero)
        {
            transform.Rotate(networkRotationDirection.Value, Space.World);
        }
    }

    private void ClientInput()
    {
        // left & right rotation
        Vector3 inputRotation = new Vector3(0, Input.GetAxis("Horizontal"), 0);

        // forward & backward direction
        Vector3 direction = transform.TransformDirection(Vector3.forward);
        float forwardInput = Input.GetAxis("Vertical");
        Vector3 inputPosition = direction * forwardInput;

        // let server know about position and rotation client changes
        if (oldInputPosition != inputPosition ||
            oldInputRotation != inputRotation)
        {
            oldInputPosition = inputPosition;
            UpdateClientPositionAndRotationServerRpc(inputPosition * walkSpeed, inputRotation * rotationSpeed);
        }
    }

[ServerRpc]
    public void UpdateClientPositionAndRotationServerRpc(Vector3 newPosition, Vector3 newRotation)
    {
        networkPositionDirection.Value = newPosition;
        networkRotationDirection.Value = newRotation;
    }

In this case networkPositionDirection and networkRotationDirection are NetworkVariables.

Now, my question is, how I can move a player not based on the Character Controller, but based on stuff like MotorTorque and WheelColliders? I have to pass them like NetworkVariables?
