Sorry to necrobump this thread, but I found it useful and thought it would be better to just keep the conversation going.

I've been doing some research on what kind of weight I can remove from my convertible without making it miserable on the street (i.e. no removing sound deadening or interior panels) and noticed something odd. Almost everything I've seen shows that convertibles weigh a good 2-300 lbs. more than a hardtop. I have to wonder, why?

At first I thought that it's because of the power top. Those motors are heavy and all, right? But according to this post, the power top motors and such only weigh 12 lbs. This page says the entire top assembly weighs 100 lbs. I can't imagine that a metal hardtop roof would be any lighter.

So then I would think the next thing that might add weight is extra chassis bracing. Convertibles have bolt on subframe connectors, and supposedly a K-member brace (I say "supposedly" because I don't think mine has one). If that post is accurate, the brace is 17 lbs. I don't know how much the stock SFCs weigh, but I'm sure it can't be more than 10-15 lbs. Is there any more bracing?

Where's all the extra weight? Is there anything else convertible-specific that I might be able to remove? I saw one post that said something about a convertible-specific, 25 lb. weight in the passenger fender But it didn't have any more details.

The added weight in a vert is all structural support that you want to have in the car.

So the chassis itself is structured / shaped differently? I can't find any information about specifically where all the extra support is. Wish I could get my car up on a lift next to a coupe.
