This Plexiglas aircraft quality windshield offers large weight savings along with added safety and strength. Accurately thermoformed by the same process used to make NASCAR Cup racing windows. Not just a piece of flat material, this windshield has all the compound curves of a piece of factory glass for an almost undetectable look. Made slightly oversized for a “trim to fit” installation. At ¼” thick it uses the stock gasket, moldings and clips. This windshield has been known to run for many years with just periodic polishing. Save 9.5 crucial lbs from the top of the car for a lower center of gravity. Plexiglass windows are not DOT approved for street use - they're for off road use only.
