Brad,
Once upon a time, we talked about a method to increase torsional rigidity by reinforcing the lower inner firewall and insides of the longitudinal. Can you post some pictures to show this method? I've looked around, and can't seem to find any. -Rusty (IMG:style_emoticons/default/smoke.gif) |

According to Richie Ginther and Lcokheed Martin the 914 flexes the most in the middle of the door openings. thus the style cage that they used in the early BP cars. They did not use the NASCAR door bars , those cages were very simple affairs. This is one of the reasons, I haven't put an Autopower cage in the car. they are not as effective as they could be.
From looking at my crash damage I get a better idea of what happens to the 914 chassis when it is loaded. Obviously this is an extreme way to find out but.... The big thing to me is the way the chassis tries to twist when loaded through the rear suspension mounts. The thought that the trailing arms are flexing in is false. The trailing arms do not push inward under cornering, they twist up and down. |
