Default Hub Bore ?

I know our bolt pattern is 5x100, and the Hub Bore is 57.11. Question is, I've been looking at wheels that say Hub Bore is 74. I'm confused.... are a 57.11 and 40 the same? Can I use a 40? Thanks.

Some wheels require adapter rings

I get that a larger bore wheel could be "fit" with an adapter ring to center it on our 57 mm hub, but that strikes me as kind of chintzy. I'd be concerned about the quality of material for the spacer, and how round it was machined, and what the clearances / tolerances are.

Are quality hub spacers readily available? Is it considered 'standard practice' (say, for race cars or something...)?? Wouldn't want to add problems down the road due a spacer wearing, going out of round, etc...

No, a 40 won't fit. A wheel with a 74 bore size will use concentric rings to adapt it down to the right size. Custom wheel mfg.'s do it this way so one set of wheels can fit multiple bore sizes.

You are way overthinking. The sky isn't falling.

Ah... now I see! HUB CENTRIC RINGS, a.k.a. "spigot rings" seem to be widely available in plastic - so apparently the hubs are not a weight-bearing part that carries any stress?
