I just sold the doors off of my red CRX; its an 88 DX. well the guy that bought them, gave me his rusted 88 Si doors to throw away for him. When he brought his Si doors to me and picked up the DX doors, he said the DX ones felt lighter. I later pulled out the door from my blue CRX(also an 88 DX) because someone wants to buy it, and weighed it. It was 69.6lbs on a bathroom scale. I then weighed the rusted Si door; it was 73.* lbs(I dont know if the rust makes it weigh any less) That makes me wonder, are the HF doors lighter, and is the weight just from the impact beam?
