Thank you. You have rated this product.

The "S" is for street. These are an old favorite of mine. They work great for street/autocross and light track duty. They dust a bit but the performance is consistent from street temps to about 500 degrees. For more serious race duty try the Porterfield R4.

REVIEWS

I red'all the parts in the order I placed and installed them in my car yesterday. I am beyond happy. The install went without a hitch. The results were fantastic. The new brakes track straight, make no noise, and stop the car authoritatively. The new rotors look pretty cool, which we all know isn't all that important, but having 6 women offer to bear your children, because your car looks SO cool is a good problem to have. Thank for great products and service.

I absolutely love my Roadster Sport headers, mid pipe and Q muffler. I have owned a lot of cars over the years and the quality of your product is truly exceptional. The ability to tune the Super Q is very much appreciated.
