Return to initial position and rotation

The project refers to a steering and suspension system from a car. The problem is that when I am releasing the arrows ( left <- or right ->) from the keyboard the wheel colliders are returning to their initial position. I want to put some code into the script file so the whole system will return to its initial position no turn button is pressed. Any idea please; Here is my code:

Script that turning left and right the wheels:

 #pragma strict
 
 function FixedUpdate () {
     if (Input.GetKey("right") && !Input.GetKey("left") && turning.right == true )
      {
      transform.Rotate(0,1,0);
      turning.left = true;
     }
     else if (Input.GetKey("left") && !Input.GetKey("right") && turning.left == true)
      {
     transform.Rotate(0,-1,0);
     turning.right = true;
     }
     
 
 }

Script that controls the car:

 #pragma strict
 var FL : WheelCollider;
 var FR : WheelCollider;
 var RL : WheelCollider;
 var RR : WheelCollider;
 var WheelFL: Transform;
 var WheelFR: Transform;
 var maxTorque : float = 10;
 var decellaration: float = 10;
 public static var steeringAngle: float = 0;
 function Start () {
 rigidbody.centerOfMass.y = - 10;
 }
 
 function FixedUpdate () {
     RR.motorTorque =  maxTorque * Input.GetAxis("Vertical");
     RL.motorTorque = maxTorque * Input.GetAxis("Vertical") ;
     FL.steerAngle =  19 * Input.GetAxis("Horizontal");    
     FR.steerAngle =  19 * Input.GetAxis("Horizontal");
     if ( Input.GetButton("Vertical") == false){
         RR.brakeTorque = decellaration;
         RL.brakeTorque = decellaration;
         }
     else{
     RR.brakeTorque = 0;
     RL.brakeTorque = 0;
     }
 }
 
 function Update(){
     WheelFL.Rotate(0,0,- FL.rpm / 60 * 360 * Time.deltaTime);
     WheelFR.Rotate(0,0,- FR.rpm / 60 * 360 * Time.deltaTime);
     CarControlerScript.steeringAngle = FL.steerAngle;
     
 }
 

Is there a way to connect those two scripts so when the wheel colliders return to their initial position the wheels of the car return too?
