WOW, the new build here will be something. Sounds like a lot has been figured out ahead of time. Very cool, great chance it will be "right" right out of the box. Two things:
Banjo st wheel: they do indeed have a look of authenticity. I know nothing about who makes a good one and who does not. What I do know is I had a real one in my '56 A coupe and hated it. The horn ring did break after a while, but the whole thing was just too flexible. Maybe my driving was a little to sporty for the wheel?? All I know for sure is that in that day, everybody thought a Nardi wheel was the cats pajamas, and everybody wanted one. If I had had the money, I woulda. Fast fwd 50 years: my Speedster has a Nardi wheel. Further note: I had a '61 B coupe also, and it had a really nice three spoke Porsche wheel (aluminum??) that was quite substantial.
Hardtop: yes indeed, that might be the next big thing for my car. I'd like that, but all has to be pretty much custom fit, so $$$. Maybe someday . . .
