Your logic certainly makes sense. Full triangulation in 3d makes the lightest and stiffest frame possible (though not necessarily the most accessible without careful design). Lotus did an experiment with the mark 8 where they tried to make the most structurally ideal frame possible. The car suffered because you had to assemble the engine with the head off inside the frame to get everything to fit. The car ended up being a dud! The tranny is a structural member in my car, and the half shafts actually function as the upper control arms (*see u-joint life in the appendix). I have a chassis book by Mike Costin from Cosworth fame that I was going to dive back into among others before I take on something like that. I plan to run the factory frame for now until the engine mods start to compromise the stiffness or I get bored. One nice thing about the later Europa is that the frame is held on with 8 bolts! You can just pop the body off with the engine and tranny in place.
These are the two main commercial offerings. unpainted one is from Banks, the red one from Spyder.
To keep this thread engine focused...I would say that this next comment is kind of out there, but given my company somehow I don't think so.
I am planning to mill/turn my own flywheel for the car. There are commercially available units, but what is the fun in that?? I am thinking about going with 7075 provided that thermal creep isn't a big issue. I am still doing my homework on it. Not a next week project but maybe in the next few months...see me lying to myself again??
