What the hey, I'll post another one.
This is a pic of the belly pan. This is the real secret why the chassis is 300% (at least that is what the FEA says) than an original chassis. The belly pan ties the entire chassis together on the under side. Also, it is the area that is the furthest from the neutral axis of the chassis. As many of you know, the farther you can move the mass from the neutral axis, the stiffer the part will be.
The belly pan was cut out on our water jet from 1/8 inch aluminum plate. It also has the added benefit of cleaning up the under carriage air so the car is more aerodynamic--although I don't think that is a major concern with this car.
