Every time you step on the brake pedal, your brake pads make contact with the brake rotor to slow your car down. The byproduct of that contact is heat, dust, and gas. NEUSPEED's cross-drilled rotors help dissipate this heat, dust and gas to reduce brake fade and cool down the rotor faster. NEUSPEED cross-drilled rotors are mill-balanced and each hole is ball chamfered to prevent cracking. All NEUSPEED rotors are cast to the original O.E. thickness for durability, and coated with a black-cadium finish to prevent internal corrosion.
