HB485N.656 - Hawk HP+ Brake Pads - Ford Mustang (2005-2008) - Rear - Some call these street pads, but they are pretty noisy and a little dusty for street pads. Good for autocross and light track duty. 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.
