Evolution Coated rotors are a direct bolt-on replacement for factory equipment. These disc brake rotors are fully coated, including inside the vanes, using Genuine GEOMET® rust preventative coating. Evolution Coated rotors are manufactured with our Tru-Cast™ technology, resulting in a precision cast and precision machined product. Rotors are OE weight and retain the OEM vane configuration for trouble-free operation. The entire brake rotor is treated with a thin layer of Genuine GEOMET® 30 coating which protects against rust and corrosion without influencing the vehicle’s braking performance. The aluminum silver color of GEOMET® 30 integrates perfectly with the style and design of today’s open alloy wheels. Want maximum protection against rust? Chose Evolution coated rotors!
