You have to run lexan windows. The weigh about half as much as glass. The doors for my bcuda are about 25 30 ponds with windows and hardware. I run stock outside handles and stock door hinges with drop in pins. You can use aftermarket hinges but the weight difference is small. If this car is going on the street know that you will need to do some big mods to make the lexan removable and not look like crap. Also to reiderate because the doors will be weak and flex the lexan windows will flext in and out a ton at speed.
