Thank you. You have rated this product.

This is an upgrade kit for those who ALREADY have our Goodwin Racing 4 piston or 6 piston caliper kits. This adds the rotors and upgrades you to our FULL 12.88" big brake kit. This will NOT work on your car if you do not already have the caliper portion.

Replaces the stock 11" rotors with big 12.88" 2-piece rotors. Includes new brackets to place the Wilwood calipers over these larger rotors.

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.

First I want to again thank you for working with me on this muffler. I have almost 100 miles on it now, and it has a nice mellow sound. a little Bass, but not too much. A little louder than stock, but not too loud. Plus it is nice inside the car with the top up. I am happy so far I bought this one.

I belong to a local Miata club, and am very active with it. When Spring comes I will tell everyone how much I like the muffler, and how great you are to work with. Maybe I can get some extra business for you.
