For a senior engineering design project I am doing a FEA analysis on the book chassis and optimizing it to increase strength while keeping the weight down. If anyone has any suggestions or has been down this road before please let me know.

cymtirx is one member who has done more analysis than most

Have a look here, some good papers and not too heavy on the maths.

I have drawn my on conclusions on the rigidity (rightly or wrongly!). Its worth looking at the Aussie car versions as their cars have to be physically tested to a minimum of 4000 lbs per deg.
, so they are used to analysing their cars.

Here is apic of what we do in Oz to pass our torsion test
may be of intrest here .
not much more steel for a lot of extra stiffness and we all ant extra stiffness
