Hi Matt,
On the Joss Cambell car as you note there were very few modifications other that converting to Austin spec sports suspension, for a fast road and occasional hill climb car I have found this to be completely adequate, and perhaps more importantly it is totally period correct so no raised eyebrows or issues with eligibility. My own car has developed and evolved over 35 years of hard use both road and track, in its original form it had a completely unboxed chassis and served me well for a while. As I went faster I started to have issues, the most annoying was jacking the inside rear wheel loosing drive round quick tight corners, this was solved by boxing the chassis, improving dampers and playing with spring rates. This time I have evolved the chassis further, improving the boxing and adding members to attach the undertray and floor, I have tried to keep the construction reasonably period authentic and not add undue weight hence the use of hot riveted construction and copying the style of the existing central stiffer. I hope that is of help.
