Product Information

Cast iron Brake disc and brake rotors can be made from many different materials. Each material has its own effect on the performance of the rotor. Some brake rotors use different design methods, such as piercing the rotor in different patterns, for high-performance upgrades to vehicle braking systems. The ideal brake rotor is usable in any weather, no matter if it is rainy or sunny. It also has the capability to easily and quickly dissipate heat from the friction of the pads rubbing against its surface.
