Thank you. You have rated this product.

These are the patented design McGard Spline Drive lugs. Non-hex wheel lug which is both a light weight lug with more gripping surface area than the stock lug (to prevent lossening up under load), and a wheel lock.

An MX5 takes 20 of these and ordering one of these kits includes 20 spline lugs and one tool. If you look really close at the picture above you can actually see the two piece nature of this lug by looking into the lug at the bottom of the picture. The part that touches the wheel (the "seat") stops turning and a bearing between that little ring and the rest of the lug allows the outer part of the lug to keep turning.

What this means for you is that the lugs are not grinding against the surface of your nice new wheels and these lugs go on much smoother than any other lug choice. If you ask what is on our Miatas here...this is the choice.

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.
