You're kidding me. lol
I've had my own body shop for years. Have you ever seen or heard what happens to a convertible, with a FULL frame, that's in for major repair or a restoration, and you remove the doors and others panels, little or MAJOR shifting can and will happen. That's why you ALWAYS,....weld in support cross beams.
Why with a glass cobra, would you think differently ?
I've even see drags cars with a much stronger support system in the frame, full cages and front sub connectors being used, and they also flex. Even Ferries ! (don't think so, as a dealer or owner)
With my experience in this field, you can believe me or not, that's your proactive buddy.
Will it hurt the body, probably not but, you can get stress cracks and star points. When I have mine on my 4-post lift, I open the doors, no problem but, I don't leave them open. If the body is glued/bonded down, you'll have a lesser chance. If it's bolted, you will have some deflection being glass. Lift the car on the frame, open the doors the see how the latch goes into the striker post, if it closes with no problem, don't worry about it unless you plan on having it up with the doors open, for say a few days to a week.
I have and like my Lone Star and it is among the heaviest Cobra on the market at $2,800 lbs.with two occupant's and full of fuel. It's frame is very heavy and strong and the body is the thickest I've seen. When I have it up on my 4-post lift, I often open the doors but, when done I shut them and can leave it suspended for weeks with no issues. I would NOT, leave them open for that long of a period.
I'm a body man and car builder as a profession, and have seen this happen, but it's your call my friend.
