New car has no cage, I know the 914 tends to flex and that the factory welded steel roofs on the 916 for what I guess was to help stiffen them, or was it for other reasons??
The 'glass top should help a little, but I was wondering about attaching tubes or the like from the factory roll bar to the windshield hoop to stiffen the car up.... Has anyone played with this before?? |

What about glassing in some square or rectangular stock to the targa top (or just a stiffening U/square channel and or X brace with glass and matt alone), one on each side by the window seal, fore to aft. to give some spine to the top. The front latch is pretty stout to pull the top to the windshield frame (compared to the rear). On the rear change out the hook and pin latch mechanism for a straight down pin type latch (like the rear trunk), then you could set the pressure to preload the rear seal, or even have the pins be adjustable fore aft within a channel to preload push or pull needed to keep things square. That would hold it a bit more steady than what is in there now and could be made to be fairly light. Obviously not a super strong approach, but could use what's there with a couple tweaks for a super duty street car.
my windshield frame will wiggle easily when I grab it and pull it back and forth, I too was wanting to reinforce the A pillar area to help. If I do this, what should I use for material, some flat bar stock bent and welded, some heavy gauge sheet stock with some beads? What about where the cowl meets the windshield base, can this use some extra support, then tie to the upright supports as I talk about above (like using 1", 1/8 flat bar stock), from windshield support to windshield support, effectively making a "U". You could bend the bar stock to get close to the windsheild base and follow the contour, wrap around the corner to the upright supports. This could be done in the front trunk compartment, or under the dash in the cabin - so it would be hidden. |
