Vehicle issues.

Hello! I am trying to make a car. all works well. wheels turn, suspension suspends, springs spring, but like this smart fellow mentioned The car will just tip as soon as some speed is gained and a turn is attempted. This is the exact issue I'm having.

The script I'm using is a transcription from JS to C# and it goes a little something (100% exactly) like this:

 using UnityEngine;
 using System.Collections;
 
 
 public class AntiFlip: MonoBehaviour {
 
     public WheelCollider WheelL;
     public WheelCollider WheelR;
 
     public float TraverL = 1;
     public float TravelR = 1;
 
     public float AntiRollStrength;
 
     public void Update () {
 
         WheelHit hit;
 
         bool GroundedLeft = WheelL.GetGroundHit (out hit);
 
         if (GroundedLeft) {
 
             TraverL = ((-WheelL.transform.InverseTransformPoint (hit.point).y - WheelL.radius) / WheelL.suspensionDistance);
 
         }
 
         bool GroundedRight = WheelL.GetGroundHit (out hit);
 
         if (GroundedRight) {
 
             TravelR = ((-WheelR.transform.InverseTransformPoint (hit.point).y - WheelR.radius) / WheelR.suspensionDistance);
 
         }
 
         float AntiRollForce = (TraverL + TravelR) * AntiRollStrength;
 
         if (GroundedLeft) {
 
             GetComponent<Rigidbody> ().AddForceAtPosition (WheelL.transform.up * -AntiRollForce, WheelL.transform.position);
 
         }
 
         if (GroundedRight) {
 
             GetComponent<Rigidbody> ().AddForceAtPosition (WheelR.transform.up * AntiRollForce, WheelR.transform.position);
 
         }
 
     }
 
 }

I actually joined Unity to try to make my own car game (me an my dad are car fanatics, but i'm a little more nerdy so...) I'll be pretty dissapointed if I cant make it work.

If any more details are needed to help people help me, just ask away in the comments (AND NOT AS AN ANSWER (unless is a question answer))

PS. did have it go fast and not tip, but the slip value was over 5 so... driving on ice =/= fun.

PPS: using WheelColliders and C# (if that wasn't clear).
