MSRP $400+up (depends on configurations/options)

Mazda Miata 89-05 (NA/NB) Genuine OEM Mazda Hardtop Only(not designed for replica/aftermarket hardtops)


This lightweight formed hardtop window is a must for anyone who would like a more aggressive look on their hardtop, OR just to shed some weight. Our G-Shields come already shaped and formed like the factory glass except at a great savings in price AND weight.

Professional installation required. Local shops in our area charge between $35-45
(Pictures above show our G-Shield installed without any molding). The window is designed to be GLUED IN PLACE like glass. The hardware around the perimeter is ONLY for decoration. We do not advise using only hardware to secure the G-Shield although many have used it this way.

• Low cost option to OEM glass (50% price savings)
• Lightweight Reduction (OEM Glass is 12lbs vs G-Shield is under 4lbs)
• Increased ventilation
• Aggressive Look
