No, that's a good point. I was going to caveat my statement suchly, but didn't want to write an internet thesis paper.
Considering some tops have no issues means when all the plastics Gods align (i.e. the tolerance stack is good), the tops come out of the Easy Bake oven to spec. I think the issue is the design is hard to hold in high rate production. That means the production speed limits product quantity, so a capacity increase (at slower speed) is necessary. I think COVID didn’t let Ford and Webasto finish the production engineering to get high rate production out of the process.
But my (2-door) top is well made. The front panels do what Ford intended; lightweight and easy to remove. You just need Kevlar butcher gloves - lol.
Perhaps most of the leak issues is with the 4-door mid section. If I designed it, I would have used structural foam verses the honeycomb inside.
The center panel is a pretty poor design IMO. That is the weak link IMO. The seals at the C pillar don’t overlap, leaving a gap and room for noise / intrusion no matter how you adjust it. The geometry of the panel also depends heavily on the front panels adding pressure; the seals lift in front and don’t make contact with the frame well unless the front panels are on. Have seen this on several copies. I’ve adjusted pins and stops on mine, but there’s only so much you can do.
The seals themselves shrink up in the cold here. It was a wind tunnel when it got -20 but even at 20, there’s a lot of wind noise that shouldn’t be there. I think next time I pull off the top, I’m going to put down a line of friction tape across the sides where the seal meets the frame. That should help ensure good contact. As it is, I’ve already had to push the seals down by adding material underneath them. I am debating just paying to replace all the seals with 2023 MY.
The manufacturing of the window seals is another problem that’s sometimes confused with hard top noise. Having Ford replace my window seals solved a whole lot of issues.
But other than that, they’re designed really well 🤣
