While we think our 5XR Grip Plate is the best thing going in the world of Miata floor pan options (the only thing going in our opinion), we created the little brother of the Grip Plate, the 5X Racing Tread Plate! This plate is lightweight aluminum, designed to fit perfectly in the floor pan of an un-carpeted Miata, provides a nice solid surface for your feet, and it looks great! It is easily installed with 4 self tapping screws (included with purchase), and we'll even ship it for free!
