Nowadays racing builds and street builds a lot of thought is put in to the braking system. Why? Here's why, when braking for a hard corner or to stop at a red light from high speeds your brakes are adding friction so your tires have as much grip as possibe. By upgrading your brake system via better pads and rotors your more likely to have more control in steering when stoping. Crossed drilled and slotted rotors disperse more heat slowing you to stop short with more friction and more control.
