So I have been playing with the idea of adding a couple more tubes to the back of the Anklebiter. If you were to replace the back half of a 914 with tubes where would you put them? Here is a rendering of the original cage (red), drivetrain (Grey), and points that need to be tied in (green).
What would you do? Attached image(s) |

The 914 chassis is far from good. I think the factory chassis stiffness is on the order of 2500lbs/deg. That is really weak. The factory chassis is a noodle.
As for the tube chassis. I would use 1.5x.045 and 1.5x.065 tubing. No need to get really big. Sheridan's car is probably the best engineered solution. It was done by a professional race car engineer. If you are going to do it I would toss the factory rear suspension and come up with something different. Mount the engine, tranny and suspension to an independent cradle. Then you could fix the 914 problems. The problem isn't flex in the rear of the chassis though. It flexes in the middle. So you will not gain much buy changing the rear. Plus the rear is pretty light because it is all sheetmetal. |
