Hey Malcolm
You may have been told this before but I urge you to read about the frame set up ERA uses and why they use it. It is true that FFR does have a stout frame. It was designed to be a race car from the beginning as the Smith brothers wanted to race cars as a hobby. That led to the FFR being produced, but making a round tube car stiff is different than making a box tube car. Most people don't really understand how it works.
Hurricane uses a frame design similar to that of ERA. Read this about round tube vs square tube:

I'm not going to bash FFR. It's a well made and well thought out car. And I know them very well as I've built one that belongs to my brother. But what I wanted was a car that was much closer in shape and profile to an original and FFR couldn't fit that bill IMO. The body is just too far off. I couldn't swing an ERA which was my first choice, (SPF was never considered) when I happened onto Hurricane and they offered what I was after. I would buy another one if I had it to do over again too.
Let me know if I can answer any questions about FFR or Hurricane.
