Hawk Performance?s HP Plus brake pad compound is ideal for Autocross and Track Day drivers looking for a high performance race compound that can take the heat of the track and get you home safely without having to change the pads. 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. Warning: Due to the dramatic friction levels produced by this product to achieve "race-level" braking, rotor wear, noise, dust and pad life may be affected. 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.
