Hi Craig,

Unforunately I wouldn't have any specific information regarding torsional 
stiffness of kart chassis.
Take a look at the following blog I wrote on FIA Kart plans. They have a 
lot of information in these plans and should provide you with some of the 
theory you are looking for.

You are correct, there is an ideal amount of stiffness/flexibility 
required to take the role of suspension to allow the inner wheel to lift 
when cornering. This is required when there is no differential and both 
rear wheels are locked to the live axle. In my opinion there is little 
information about this topic, as most studies done are on karts with 
suspension and this changes things.

Best of luck with the project. Let us know how things go.

I know that that an ideal figure would allow some deflection to take the role of a suspension element and also allow the inner rear wheel to lift when cornering... I've contacted NatSKA about a copy of the book and awaiting a reply. Thanks for that.
