Porterfield R4-S Rear 01-05 Sport Brakes : 01-05 Sport Brakes

The "S" is for street. These are an old favorite of mine. They work great for street/autocross and light track duty. Most track days this is what I have in the rear of my 99 track toy. They dust a bit but the performance is consistent from street temps to about 500. For more serious duty try the Porterfield R4. Carbon Kevlar construction. Does not include replacement springs, clips, etc. These fit the "sport" brakes on 01-02 years which became standard for 03 and beyond including the MSM.
