Thank you. You have rated this product.

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. One set needed for front, one set for rear. Does not include replacement springs, clips, etc.

I received the Roadstersport II, and I wanted to compliment you guys on an awesome product. The Miata should have these on from the factory. They make a great sound, that is not obnoxious at all. The exhaust also installed seamlessly!!! I will buy all of my Miata stuff from you in the future. Thanks,
