*Performance Ceramic ('Z' Compound Code)* Performance Ceramic is engineered to reduce brake NVH (Noise, Vibration and Harshness) creating a quieter performing brake pad. Furthermore, the ceramic brake pad formula has a linear friction profile that allows your ABS brake system to work more effectively. With Performance Ceramic you can expect reduced brake pad wear, lower dust output levels and a rotor-friendly brake pad. * Increased Stopping Power * Increased Rotor Life * Extended Pad Life * Ultra-Low Dust * Extremely Quiet * Stable Friction Output *HP Plus ('N' Compound Code)* HP Plus utilizes a unique Ferro-Carbon, high-tech friction material that was developed and manufactured for sport driving in autocross, Solo II and “track day” applications. The Ferro-Carbon formulation offers lower wear rates and higher torque values than other competitive materials. Extremely high coefficient of friction makes HP Plus the perfect upgrade over stock for high performance streetcars used in autocross competition or that experience repetitive, heavy braking. * Extremely High Friction Output * Fade Resistant * Worthy for Autocross & Club Racing Events *Note:* Hawk Performance burnishes its HP Plus brake pads as a final step in the factory, but all brake pads have to be bedded-in with the rotors (new or used) that they will be used against. Properly bedding-in new brake pads results in a transfer film being generated at the pad and rotor interface to maximize brake performance.
