Chris the new wheels are a great upgrade and your car looks awesome with them.
And (not that anyone asked) my opinion is that wide-5s look best on these cars, with 16-inch ones being tops, but that other Porsche wheels can be credibly substituted. 550-0090 wore later (C-era?) wheels for a while in the late 60s and early 70s, as those were sometimes used as upgrades to these cars toward the end of their racing lives. And, of course, Porsche did fit a set of Rudge knock-offs on one of the early cars for the Paris Motorama.
Eight-slot Mangels can be made to mimic that look pretty well.
Fuchs? A bit of a stretch, I'd say, but I would not throw a Spyder with them off my lift...
But a case could be made for 944 Turbo spares ...
