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.

These fit the "sport" brakes on 01-02 years which became standard for 03 and beyond including the MSM.

I think that Brian Goodwin is the perfect example of what is good about the aftermarket industry. He is one of the few vendors that actually cares about his customers. He is the example that all companies should be trying to emulate when it comes to customer service. Not to mention his ingenuity and desire to improve on what is already a great car. I have never had a "bad" experience with Good-win-racing. Well, except for the constant temptation to SPEND MORE MONEY.

Hey Brian, Recieved my Borla Dual Muffler Sport today from Fedex, and installed it in about 30-45 minutes. An Outstanding product with absolutely no drone throughout the power band, it sounds powerful, not at all like one of the ricey "fart tubes" that can be found elsewhere online. It has perfect like OEM fitment. Great prices, and great products. Product was shipped promptly and arrived as ordered. Would buy again!
