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?? |

Guys you are missing the main problem. Not enough complete box sections in the chassis. If you can complete more boxes, increase the cross section of existing boxes, you will gain eponentially more stiffness than you would if started making all of these band-aids.
Look at the early aluminum Monocoques. They used very few tubes and many panels. You could take the factory tunnel out and put in one of a much larger cross section. You could increase the size of the factoy rocker boxes. Which are significantly stiffer than just about anything your are going to add or replace it with. Make a huge backbone through the car. This is probably the best thing you could do for the strength of your chassis. You could build a very light weight frame of steel tubing for a seat that basically fills up the interior of the car. Make places to two seating areas and skin the whole thing in aluminum. Attach your frame to the basic 914 chassis and bond and rivet the aluminum sheeting to the frame and the chassis. This would increase your torsional stiffness incredibly. Yes it will be a massive amount of work. Would it be worth it. Absolutely. Attached image(s) |
