Well I found a link from a sponser on another board about chassis stiffening and body flex on Uni-body cars. Really interesting and shows how the affect of body flex and what not. Anyways here are their suggestions. All good ideas which I had all ready planed on sorta except the front crossmember Idea, gotta add that one to my plan. Anyways check this stuff out, OH BTW this is for a mopar, but it is still a Unibody, so I think we can all learn something here.
Front crossmember
Inner Fender braces, I plan on building somehthing similar
Sub-Frame Connectors
Engine Compartment Brace, I plan on tying my inner braces into this.
This is a video demostrating chassis flex and what it looks like when it is fixed.

The only problem I see with this whole setup is that the inner braces and engine compartment brace to hooked to a piece of 16-18 sheet metal (the firewall), not very strong, but I guess in total it evens out. I planned on running a piece of square tubing behind the firewall and joining these braces together. Another problem, since I will not have shock towers, I plan on running a diagonal peice of tubing from the inner fender/engine compartment mounting spot to the front crossmember to make up for the lack of shock towers.
Now my main question, why is nothing ever stiffened in the back? I mean most Uni-Body cars have very thin rear frame rails (usually half the thickness as the front), but I have never seen anyone do anything back there..... What do yall think???
The reason I am asking this is because I will be fiinished with my floors in a few weeks and I am starting to plan ahead for the next stage.
