Mr Bruce, I have an answer for you. The following is a quote from Fred Wood, a retired GM chassis engineer. I had posed your question to me to him.
"This would normally be done on an MTS Hydraulic fixture which would alternate beaming and torsion alternating inputs for a set period of time. Stiffness would be measured before and after. I do not think that this is something a small manufacturer can do. Very expensive and complex. I think the best you coul do is measure the torsional stiffness of the frame new and then do it again after extended use. The way you have that frame designed I can not believe it is an issue. You could show a picture of the Shelby series 1 frame compared to yours, as it would compare very favorably. Fred"
I will be testing for torsional stiffness next week, after the frame is completely welded. I will let you know the results.
