SportStop Cross-Drilled Rotors further increases performance by pulling gas and heat away from the friction contact zone. By removing these gasses, temperatures drop and brake performance increases. SportStop cross-drilled rotors are a great first upgrade for the original brake systems, delivering winning performance and increased stopping power. SportStop rotors improve brake system performance by wiping away the used friction material that otherwise accumulates between the rotor and pad. This keeps fresh pad material exposed to the rotor surface and promotes more consistent braking performance.
