    Default 205 chassis rigidity

    The basic 6 point cage I am getting will mount in the usual spots. Apart from safety I want to link up the suspension points to really increase stiffness and help the suspension work properly. I already have a large upper strut brace.

    Should I def be trying to place a link between the front (windscreen) arms of the cage and the top of the strut towers? ie penetrate the firewall with some triangulation, or will this just add 2%?

    More steel, means more rigid but also heavier. You need to decide how legal you want it to be. eg

    street legal?
    hillclimb/supersprint legal
    targa legal?
    FIA legal?

    Yes, i sought of forgot about the legalities of the firewall. Apart from that, I wonder where the main twist in the body occurs between front and back (around the doors and roof?)

    It's more the legalities of each of the bodies listed. What's legal in sports sedans isn't legal in improved production. Then anything more than a half cage isn't street legal. You just need to work out what you want to do with the car.
