The "S" is for street. These are an old favorite of Brian's. They work great for street/autocross and very light track duty. They dust a bit but not as much as the Hawk HP Plus and the performance is consistent from street temps to about 500. For more serious duty try the Porterfield R4.
Carbon Kevlar construction so these are easy on rotors. Does not include replacement springs, clips, etc.
