Hahaha. I just spent 20 minutes doing the calculations for polycarbonate weights. (Length x Width x Thickness x 1.2 = weight of polycarbonate sheet). I came up with the same answers.
Open windows are bad for aerodynamics. Worse than carrying the extra grams a full window would have over a partially open one.
I wonder if that is where I read the 3mm thickness then - back when I was considering making mine a sports sedan.
The doors are now going to end up closer to 5.5kg. My current fibreglass ones are only a bit over 10kg. I still need to add the external door handles to that, so it may as well be 6kg. I'll be shattered if I only save a kilo or two out of all this work...
