As part of our ongoing series on Mazda Miata convertible tops and replacement parts, today let’s examine rain rails. Rain rails are a molded piece of plastic, which can only be seen when the top cover is off the top frame. It is not visible under normal circumstances.
The purpose of the rain rail is to keep water from getting into the trunk of your car. They are attached to the bottom of the top, underneath the rear window.
If your existing rain rail is in good shape, it’s common practice to just transfer your old rain rail to the new top. How do you know if your rain rail needs to be replaced? If it is cracked, or if you have an issue with water getting into your Miata’s trunk, then you need to buy a new one. Otherwise, if it seems to be intact and your trunk is dry, there is no need to buy a replacement rain rail when you replace your Mazda Miata top.
If you do need to buy a new rain rail for your Miata top, we sell them and ship them along with rivets and instructions. As always, if you have any questions, please feel free to ask us!
