There is an upper limit to how fast you are going to stop the forward momentum of the car. You can stop the rotation of the wheel, but if you stop that and their is still forward momentum all you are doing is sliding forward on the tires like ski's. The point of the post is that upgrading only makes sense from a heat standpoint if you are on the track. Otherwise brake fade isn't a concern which means the stock brakes just have to work the first time. The limiting factor then is determined by the weight of the car and the coefficient of friction between the tires and the road.
