The original factory top, referred to as the Factory Style Top, is a 2-piece design with the window section zippered into the top deck section and fits model years 1989–1997. This 2-piece top design retains the same quality as the original, with an UltraMaxx tinted glass rear window that does not zip open and is heated by a built-in defroster system. The top has the factory-original style deck seams and overlapping quarter panels. The pre-punched plastic retainers make it easier for a professional to install.
The premium black Trilogy Acoustic Vinyl used in its manufacturing exceeds the original appearance and feel. It is an acoustically enhanced vinyl with a twill (cloth-like) pattern and 100% polyester backing for superior strength and longevity. The non-zippered window has received DOT approval and comes with an emblem to ensure compliance. From the exterior, the edge around the window has a clean, finished appearance with no piping needed to hide stitching, gluing, or imperfections that may arise from other bonding methods. The fabric has been carefully notched by a computer-controlled cutter around the radius to ensure proper adhesion around the entire perimeter and eliminate potential leakage. The technology is unique and protected by worldwide patents, and we guarantee the bond to the original purchaser for the life of the vehicle. Your new Miata Replacement Convertible Top arrives immediately ready for installation. That means no cutting or sewing is required. These tops have been time-tested in hundreds of installations, which is why we feel comfortable providing a 100% guarantee that you will not have any problems with the fit.

- Long-Lasting Good Looks
- This fabric is sturdier than that found on the original Miata convertible tops.

- A rain rail is a U-shaped, molded ABS plastic piece that attaches to the rear bottom of the convertible top. It directs any water collected out drain holes to keep it from entering your interior cabin and trunk.
- To order the rain rail, use the part number 11-18-MX5-001.
ABOUT TRILOGY ACOUSTIC VINYL
Trilogy Acoustic Vinyl was developed specifically to provide a high-quality, long-lasting topping material suitable for most types of removable soft tops. Trilogy has superior performance characteristics compared to other vinyl toppings, and the surface texture was designed to look just like the expensive twill cloth topping found on luxury vehicles like Mercedes, BMW, Audi, Bentley, and Rolls Royce.TRILOGY is QUIET
TRILOGY Acoustic Vinyl is a 45 oz. heavyweight two-ply composite. While it may sound impressive, what this actually means for you is that it reduces noise! In comparative tests, TRILOGY Acoustic Vinyl was shown to reduce interior noise significantly. Quite simply, tops made with TRILOGY Acoustic Vinyl will provide you and your family with the quietest and most comfortable ride.
TRILOGY is DURABLE
Trilogy Acoustic Vinyl is not just a pretty face. It is a 2-ply composite material with a heavy-duty outer layer of PVC and a 100% Polyester laminated backing. Polyester is much stronger than cotton or poly/cotton blends in terms of abrasion resistance and tearing. Furthermore, polyester resists rot and mildew. Polyester is so superior, in fact, it is the only material specified for use in all European luxury convertibles.
TRILOGY is GREAT LOOKING

TRILOGY Acoustic Vinyl was designed not only to be the strongest and most durable topping vinyl available but also to be the best-looking as well. The outer surface of the topping duplicates the twill weave pattern of expensive cloth toppings used in the most exclusive automobiles, such as Aston Martin, Rolls Royce, Maserati, and Ferrari. Either as a direct replacement for your original cloth top or as a fantastic upgrade from an existing vinyl top, TRILOGY Acoustic Vinyl is the best-looking, most affordable alternative.
