Now we are thinking about how to make the parts that go around the rear wheels. Because an original Cobra chassis has a 90 inch wheel base we were constrained with this chassis to have a 90 inch wheel base as well. One thing I can tell you all for sure is a 90 inch wheel base is TERRIBLE to engineer around. There is simply no room to carry the loads from the rear wheels to the front wheels. The load path gets chopped up around the rear wheel well panel by the driver's back. The driver is actually sitting BEHIND the front of the rear wheel. As such, it is an engineering trick to carry the loads efficiently and keep the chassis stiff and light.
I will show you pictures of our solution as soon as we finish them. Let's just say the block we start with is about 100 pounds and ends up being around 5 when we are done! I don't have the exact weights, but I will post them when we get them. It is an EXPENSIVE solution, but it is really the only solution that will work.
