Rain Rail
The rain rail is a plastic "rain gutter" (the cross section is shaped like the letter "U") that pop-rivets to the convertible top and every Miata has one. It is located at the base of the top below the window (you can't see it until you remove the top) and funnels the water that runs down between the top and the body of the car to drainage holes.

If this piece is cracked or brittle, serious water damage can occur. If you are planning to do a top installation yourself purchase any top WITH the rain rail your installation will go much smoother. If installation is to be done by a professional you can save money by using your existing rain rail if it is in good shape. The savings by not purchasing a rain rail needs to be weighed against the cost of a longer install time.


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,

Good morning Brian, I finally got a chance to put the exhaust on, great advice, it's just loud enough, solid product. I'm running without the baffles, sounds great in power band. Take care, you have all my future upgrade business.........regards.
