We'll know on the side windows and door windows when we get johns kit ordered. The front windshield has an *cough* accident on removal, and the rear might just go with the hatch.
Usually a speedglass window of equal thickness is 50% less weight.
A factory drivers side window weighs 8.2 lbs.
So that would be roughly a 8.2lb weight savings if you replaced both windows.
the rear windows (rear 1/4's) are about 2 lbs.
So again if you replace both that'll be about 2 lbs.
That back window is VERY heavy, so is that windshield...thats where the majority gains will be.
