[Rigidbody2D] how to implement drifting in a top down racing game ?

Hello everyone, I am trying to make a top down racing game similar to VS.Racing2[youtube and am kinda stacked with the drifting feature, from what i understood by watching and playing that game i ended up with this code, however, the physics still doesn't feel right :

         void FixedUpdate ()
         {
                 //move car "forward"
                 rigidbody2D.AddForce (transform.right * moveForce * Input.GetAxis ("Vertical"));
                 //limit car velocity    
                 rigidbody2D.velocity = Vector2.ClampMagnitude (rigidbody2D.velocity, maxSpeed);
                 
                 //turning the car 
                 if (Mathf.Abs (Input.GetAxis ("Horizontal")) > 0) {
                         //rotate body 
                         rigidbody2D.angularVelocity = Input.GetAxis ("Horizontal") * -rotationSpeed;
                         //increase rotation force 
                         if (rotationSpeed < 300) {
                                 rotationSpeed += Time.deltaTime * 20;
                         }
                         //add opposite force (drift)
                         rigidbody2D.AddForce (-transform.up * (rigidbody2D.velocity.magnitude / 2) * driftStart * Input.GetAxis ("Horizontal"));
                         //decrease drifting multiplier 
                         if (driftStart > 0.2f) {
                                 driftStart -= 0.01f;
                         }
                         //decrease general speed 
                         if (maxSpeed < 10) {
                                 maxSpeed -= 0.5f;
                         }
                 } else {
                         //reset 
                         driftStart = startDriftStart;
                         rotationSpeed = startRotation;
                         maxSpeed = startMxSpeed;
                         
                 }
         
         }
 

 

what i need to know is that either my approach is correct or not, so maybe am doing it right but i just to keep changing the values in order to have the best result, or, maybe there is a better way to do such a thing and am doing everything wrong since the start.

I would really appreciate your help. Thank you
