Hover Effect with more rays as turbines?

Hello,

along time ago I found this script that creates a hover effect that works well with small objects (because the boundaries are nearer to center-pivot where the ray starts).

 private var rb : Rigidbody;
 private var currentHeight : float = 0.0;
 private var hoverForceMultiplier : float = 0.0;
 private var hoverForceApplied : Vector3 = Vector3(0, 0, 0);
 
 function Start() {
     rb = GetComponent.<Rigidbody>();
 }
 
 function FixedUpdate (){
     // -- find hover distance and add force to make hover        
     var rayHit : RaycastHit;
     if(Physics.Raycast(transform.position, Vector3.down, rayHit)){
         currentHeight = rayHit.distance;
         if (currentHeight < (hoverDistance - Time.deltaTime)){
             // find percentage of currentHeight below hoverDistance
             hoverForceMultiplier = (hoverDistance - currentHeight) / hoverDistance;
             hoverForceApplied = (Vector3.up * hoverForce * hoverForceMultiplier) + (Vector3.up * 9.8);
             rb.AddForce(hoverForceApplied);            
         } else {            
             // apply anti-gravity force for half distance above hoverDistance
             if ((currentHeight - hoverDistance - Time.deltaTime) < (hoverDistance / 2)){
                 hoverForceApplied = (Vector3.up * 9.8) * ((hoverDistance - (currentHeight - hoverDistance)) / hoverDistance);
                 rb.AddForce(hoverForceApplied);
             }
         }
     }
     Debug.DrawLine(transform.position,Vector3(transform.position.x, transform.position.y-hoverDistance, transform.position.z), Color.green);
 }

However, it is better to have multiple rays checking the distance to the ground as a hovercar has different amounts of turbines instead of having one ray starting from the center of the car.

I have thought about a ray-array variable in the inspector that creates a new ray with a position variable to place it in the right direction where the turbines are, but I don't know overall how to solve this.

Please, could someone point me in the right direction?

Thanks in advance!
