Side under spoiler made by Shorin of Japan for the NB (1998-2005) Miata. This side spoiler adds a slight lip to the stock side skirts and is a great complement to Shorin’s front spoiler. This will give your Miata a lower and more aggressive appearance! Please note that it will only fit with the pictured OEM Side Skirts. It will not fit the "big tupperware" Side Skirts that go higher.Learn More
