Glass weight
Just removed my windshield and rear hatch glass, and installed 1/4 inch poly from Shields Windshields as replacement. 2013 370Z. Here are weight results
OEM windshield 23.8 lbs
Poly windshield 16.0 lbs
7.8 lb savings
OEM rear hatch 17.8 lbs
Poly rear hatch 10.4 lbs
7.4 lb savings
Full disclosure on weighing technique: I weighed myself on a good bathroom scale, then weighed again holding the glass and subtracted to get the difference. Not too scientific, but should be close enough.
