Vossen:
24lbs front and 26lbs rear
(20x9) front and (20x10.5) rear
Volk (Current Setup):
19lbs front and 21lbs rear

adding 5lbs to each wheel is horrendous. it will make your car significantly slower.
i went from the stock g37 18s (which were ~27lbs) to the 370z s-tunes (20.5lbs and 21lbs) and stock tires(28lbs) to conti DWs (25lbs and 27lbs). let's just say it was the best $18XX i've ever spent on my car. i can lift the a wheel+tire with 1 arm now too LOL
simple google search can explain why... if you're a 'performance' guy, then vossens are definitely
not the way to go.
you're on the g37 forums and if you look around you can find a post by a mechanical engineer (im banging my head against the wall because i cant find it) who compared different gains an losses from different mods from a scientific perspective. he concluded that rim upgrades are, by far, the best performance upgrades a car can receive (besides forced induction).
here's a good video, btw:
