A new top for your Mx5 is a necessity but it's also an opportunity for personalization. Robbins' Panorama Tops feature a huge rear window that is 22% larger than their Streamline style tops, a great improvement especially if you have a roll bar to help increase visibility. The Panorama Window is made from Robbins' ultra-clear 40 gauge UV coated vinyl for durability against sun damage and scratches. Rain guards above each door window keep moisture that rolls off your top from falling onto your door panel (or sleeve) if you have the window down. Haartz Vinyl - The Haartz vinyl is 38 oz. Cabrio Grain, the same weight and pattern found on original Mx5 tops. The backing is 100% Polyester for strength and pliability, and bonds better to vinyl. Cotton backing used by other companies is less expensive and shrinks and becomes brittle over time. As always, these Robbins' tops are manufactured to Robbins' industry leading standards for quality, superior fit and value.
