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?? |

QUOTE You guys surely jest.... The A-pillar weak. Please. Have you ever cut a windshield off? There is a bunch of steel in there. Several thicknesses of sheet metal. Potentially, in a hard collision, the windshield frame may try to crack at the point where the rigid frame meets the rest of the unit body. Those "stiffening plates" In my opinion were put there to reinstall a previously cut-off windshield frame. Nope. And don't call us "Surely" (IMG:style_emoticons/default/laugh.gif) All I can tell you is "every single" restoration project I've tackled (2 911's and 2 914's) has had cracked a-pillars. We're currently looking at a 914-6 on a rotisserie (sic) that the windshield posts move more than 1/4". Factory GT's have the stiffening plates welded in and these are cars that have a clear history of "never" having the windshield cut off. I'll cite the aerospace engineer that was looking at the car when we were contemplating the factory stiffening kit... "It's funny how many good-ole boys think they're smarter than the factory engineers". So, I'll go by experience with all my 911's and 914's. A-Pillars crack. A picture is worth...?
