If all else fails, I might just take mine off but I don't want to because the car is torn apart enough and it won't be easy. It's got to be heavy, real heavy. It's what separates the weight difference between a coupe style.
I ask because I am looking to get a fiberglass hatch with lexan window. I have been told just the fiberglass hatch with stock window removes 75lbs, I am sure the glass has to weigh a lot as well.
