Actually, two reasons for the windshield to break, lack of a center stiffener bar, and the lousy design of the flimsy frames available (Kirkham is working on a replacement now). Actually three reasons, some of the screws that are supplied for the windshield frame are too long, run them all the way in and they actually hit the edge of the windshield itself causing a pressure point that given the right circumstances, will cause the glass to crack from the edge inwards.

100,000+ miles of use, road and race track, and I have yet to crack one of my cobra replica windshields. Maybe I'm just lucky......
