Miata (1989-2005)

When the weather is fair and the top is down, nothing beats the joy of driving a Miata convertible! However, when the weather is bad or if you are on a long drive on the freeway, you just can't beat a Hardtop. The good news is that now you can have the best of both worlds!

Our Removable Miata Hardtop, which was introduced in 2000, was designed to enhance the overall sports car look with a totally unique "Speedster" roof silhouette. This exciting Smooth Line design features a curved, flush mounted, convertible sized, rear window for a very sleek and low look. Coming or going, our Hardtop will give your Miata a very aggressive stance that will definitely make heads turn!

Adding a Smooth Line Removable Hardtop is the best styling and practical improvement that can be made to your Miata. Our custom designed Hardtop will give an exciting, clean and smooth look to your Miata while comfortably protecting you from unwanted noise and weather.

The interior is upholstered in a thick OEM felt automotive headliner material that will compliment the interior of your car. This headliner significantly absorbs road noises and also is an excellent insulator against heat or cold. Now you will be able to have normal conversation or really enjoy your favorite music on your stereo. Great on long drives!

Our rain guards will help keep your seats dry when the door is opened. This new Hardtop is complete with thick rubber moldings attached to ensure a weather tight seal. When your Miata is parked, a Smooth Line Hardtop also adds additional security for the car and personal items.

Attachment is very simple and fits all 1989-2005 Miatas.  Simply lower the convertible top in the normal position and attach the Hardtop. The Smooth Line "Speedster" Hardtop attaches to the windshield at the same point as the convertible top and at the sides near the convertible pivot point. The "Speedster" Hardtop does not require the use of the "Frankenstein" clamps in the rear for a secure fit.

The footprint of our Hardtop is the same as the convertible top and the thick rubber seals against the factory plastic molding on the deck, eliminating abrasion on the painted surface. The Miata Hardtop only weighs approximately 50 lbs, is easy to handle, and can be removed in seconds! Very easy on/off!

All Smooth Line Hardtops are made in the USA by American craftsmen. Quality is an absolute! All production is done in house to insure high standards. The shell is a premium grade automotive fiberglass composite with dual panel perimeter construction, which makes it very strong but light weight. The exterior is finished to perfection with two coats of smooth black urethane primer ready for a top coat color of your choice. For the best color match, we recommend using a local high quality auto body paint shop that can computer scan your Miata to match the paint.

Every Smooth Line Hardtop is custom made to order by our expert trained craftsman one at a time and are assigned a unique serial number. We have a one-year Limited Warranty against defects in workmanship or materials.

The standard Smooth Line Miata Speedster Hardtop is finished in a smooth, ready to paint, black primed urethane exterior finish with charcoal gray headliner, tinted Plexiglas window and all attachment hardware. No holes to drill, no modifications and nothing extra to buy! Please see Installation Instructions for details.

Customer Testimonial

"Again, thanks…I’m real pleased and real glad I opted for the vinyl top.Thanks for a great hardtop…looks great."  -D.C., NV 

"I received my new vinyl top today and it is great. The workmanship is very good. I have purchased fiberglass aftermarket parts from other companies but your quality far exceeds theirs. It is a lot quieter inside the car with this new top on. I used to have an Allante with a removable Hardtop, that top moved around when you went over a bump or on a rough road. Your top does not, it makes no noise and doesn't move." - R.M., WA
