Car wheel collider bounce! Help

Hi, I am quite new to making cars and I am currently making a free roam game. The problem is that when i start driving, even the slightest speed my car starts twitching from side to side… I will try give as much details as possible, apart from that please help

^This is just a screen shot of my current scene and how my Buggy/Car is setup + how the wheel colliders are set.^

@ImThatZombie Try setting the center of mass to something slightly around -1 on y axis.

Consider using antiRoll script, here`s mine, copied from tutorial and bit tweaked to work with my code

public class AntiRollBar : MonoBehaviour
{
public WheelCollider WheelL;
public WheelCollider WheelR;
private Rigidbody carRigidBody;

public float AntiRoll = 5000.0f;
// Start is called before the first frame update
void Start()
{
    carRigidBody = GetComponent <Rigidbody>();
}

// Update is called once per frame
void FixedUpdate()
{
    WheelHit hit = new WheelHit();
    float travelL = 1.0f;
    float travelR = 1.0f;

    bool groundedL = WheelL.GetGroundHit(out hit);

    if (groundedL)
    {
        travelL = (-WheelL.transform.InverseTransformPoint(hit.point).y 
                - WheelL.radius) / WheelL.suspensionDistance;
    }

    bool groundedR = WheelR.GetGroundHit(out hit);

    if (groundedR)
    {
        travelR = (-WheelR.transform.InverseTransformPoint(hit.point).y 
                - WheelR.radius) / WheelR.suspensionDistance;
    }

    var antiRollForce = (travelL - travelR) * AntiRoll;

    if (groundedL)
        carRigidBody.AddForceAtPosition(WheelL.transform.up * -antiRollForce,
            WheelL.transform.position); 
    if (groundedR)
        carRigidBody.AddForceAtPosition(WheelR.transform.up * antiRollForce,
            WheelR.transform.position); 
}

}
