While using the car the lay person will hardly get into the scientific details of the car ride. Of course the lay person will know some basic facts such as that the car powers itself by burning the fuel. And that this fuel is burnt in the engine and because of this the engine can get quite hot so the engine is kept cool with the help of coolants.
But then if you pause and think that when you start the journey there is a lot of fuel in the tank and the car is at rest. And when you end the journey there is less fuel in the tank and the car is again at rest. Therefore where did all the energy that burning the fuel generated go? Since the car is not moving the energy is not present as kinetic energy in the motion of the car. Well some of it will have gone in overcoming the wind resistance and some of it in overcoming the friction of the road. But a lot of it gets dissipated as heat every time you apply the brakes. And therefore you can imagine there is a lot of heat generated in the area of the car where the brakes are applied. This heat needs to be efficiently removed otherwise the components comprising the brake system will get damaged.
And the component that does that are the brake rotors. Brake rotors have to generate a lot of friction so that the car stops quickly and at the same time they must quickly get rid of the heat generated. Depending on your driving style you have the option of various types of brake rotors. The main difference is some are more suitable for getting rid of the heat and are good for normal driving and some are good for generating a lot of friction and are good for performance driving. Some of the latest brake rotors try to strike a balance between the two.
If you are looking to have a great performing car you should consider products such as brake rotors. You can see the latest ones at www.ilovebodykits.com
