I found a used set of 20" Vossen wheels locally. They are not the 5 star pictured in my sig, but... Anyway, they came off a Lexus. The bore size is a 74.1mm or 2.92in. How do I know if these are hubcentric? If they are not... will hub rings affect ride/handling? If I do need hub rings, how do I determine what size?

My Ride: 530I Silver gray with gray leather with Premium Package, Logic 7 Premium sound system with Ipod interface, xenon adaptive headlights, Active steering, Power retractable rear sunshade, Comfort seats, Cold weather package and M5 OEM 166 wheels, Sprintbooster. Ceramic Tint all around, Bilstein Sports shocks with Eibach springs, Brake performance Rotors and Axxis ceramic pads.
I'm not sure but, I think our car have 72.4mm hub. that would mean you need a hubcentric ring to fit. Another question would be the offset.

Our hubs are 72.56. You'd need centering rings on those. Size? 74.1 - 72.56 = 1.54mm rings needed.....or closest you can find to this figure.
BTW, how do you know the offsets are correct?

In my memory is correct, BMW PDC is 120, Lexus 114.3 which should not fix

Not only the hub ring, but also need to consider the PDC.

I am confused. PDC? Sorry if this is a stupid question.

I think he means the lug pattern or PCD (Pitch Circle Diameter)...120 X 5 is BMW: 5 lug pattern on a circle with a diameter of 120mm.
Different cars & wheels have different diameters. As for that offset, I wouldn't bother with these wheels...you are just asking for vibration with thick spacers, esp. up front. Pass on these!

I knew what my bolt pattern was... but I was unfamiliar with the PDC acronym. Thanks for the clarification!
