Wish your C4 Frame was Stiffer?

The flexi frame is the biggest down fall to the C4, hands down. It is the one (and only) thing that I liked better about my C6. I'm super keen on this (or any thing) that will stiffen the twisting aspect of the frame. I wonder why this unit uses heim joints; it SEEMS like rigid mounting points would add to frame stiffness more than pivoting mounting points.

Just curious as to how this works. Dont the frame rails run front to back? How is adding, what is essentially another rail, going to stiffen the chassis? I can see it making a difference for launches but torsional stiffness would be the same. The idea behind the x brace is to link the two sides together to increas the torsional stiffness. This idea is still only one side.
Im not trying to bash the product, just trying to understand the reasoning behind it. Perhaps there is something I am missing.

The design looks to me to mimic the strength of an I beam, so basically it is going to reduce torsional flex. The cross brace does the same thing, it just goes across the car and may actually be more effective, but this design undoubtedly would yield noticeably good results as well. You have two tubes running in parallel down the length of the car to the points where flex from the suspension will transmit through the frame, so yes, it will increase strength.
The C5 & C6 has basically the same frame design as the C4, it is the methodology behind building them that the engineers were able to create a much stronger frame. Mainly Hydroforming of a single frame rail from front to back, but many other improvements as well, whereas the C4 was put together with a bunch of pieces and spot welded together...
I'm interested in seeing what this will cost as well

It looks like the reason it works is because it is a tensional member of the frame. If you have a beam with two wheels, one at each end and put weight in the center, the beam will sag (bend downward) in the middle. If you add something like a rod under the beam it will try to stretch not allowing the frame to bend down if it has attaching points at each end an one in the middle. Sounds interesting.

Anything to strengthen the chasis is an improvement.
