It looks like someone needs to start a proper build thread--welcome to the site!

Yes it is amazing how flexible they can be. This however is for a 2001 996 convertible. I kind of expected that it would be flexible. The Lotus Elise is in this same range of flexibility. You're right in that if you have a flexible frame and a stiff suspension, that the frame is going to be flexing a lot instead of the suspension taking the flex. I will be stiffening my frame up quite a bit. I'm shooting for a stiffness of 40,000'#/degree. In other words 10 times stiffer than this frame. I did some finite element analysis on the frame that I am building and it seems that I will be able to achieve that. We will see though sometimes computerized results and real world don't line up. Garbage in garbage out. But I'm hopeful. By the way...I thought this is the build thread? Am I missing something? Let me know. Here is a list of torsional stifness http://blogs.youwheel.com/2014/04/25...ehensive-list/
