There is a lot more to that than circumference. Like WEIGHT as Escobar929 said...Stop googling and start G35drivering

[Your search query here] site:g35driver.com
works 100x better IMO and uses the google cache... good for info.. bad for pics..but hey... something is better than nothing...
but seriously... start g35drivering... there is like a million people here who have EVERY set up possible on a G ... if you are not here for their experiences / opinions ... then you really should not be here....
so... what if you had 20'' WEDS dry carbon sport wheels which weigh like 6-7 lbs each... (about 16-20 lbs lighter than most wheels on our cars)... you think the angular momentum of a 6 lb 20'' wheel is more than a 25lb 19'' wheel? you are sorely mistaken...
just for kicks... lets assume both wheels have roughly a uniform distribution of weight... and lets say the 20'' wheel weighs X lbs... then to have equal angular momentum w/ a 19'' wheel the weight would have to be:
L = I (moment of inertia) / W (omega- angular velocity)
lets assume W is the same for both...
that would imply that to have equal angular momentum, the two wheels would need to relate as so:
I(19'') == I(20'')
=> 1/4 * M(19'') * R(19'')^2 = 1/4 * M(20'') * R(20'')^2
=> M(19)*19*19 = M(20)*20*20
which of course implies that:
M(19) = 1.108 * M(20)
this of course means ... that approximately, if the weight of the 20'' wheel was about 88% that of the 19'' wheel, then they would have essentially identical acceleration... so... get some nice 20's that dont weigh a lot... and you will be set...

LMAO ... family guy... ha ha... used to think it was funny until they drove the same 2 successful Simpson's jokes into the ground... But festisio is REALLY a word... oh come on... don't tell me you don't know what a festisio is... you festisio.... ha ha rolls off the tongue nicely...
But ... light wheels FTW lol... hey im bored at work... you have any idea how much i got payed to explain some logic in excruciating detail about wheel weights lol - now thats passing time...
Simpson's, Futurama FTW... family guy... ehhhhhh.... ill give the first 2? 3 seasons a pass... after than it becomes more like a... hey... you have watched this show and had some good times... now that you are on this side of the fence let me (seth-douche-mcFarlane) stop trying and bleed my fans dry with non stop meg bashing and the same jokes repeated 10x over... i really feel cheated watching that show anymore...

apparently you are the noob. hope you paid attention to the lil physics lesson above
try googling that homes!

hope you know most of this is in good fun and i no way do we dislike you are anything
some of your ideas are just kinda out there, like way out there
but in no way does it mean you should listen to us if you dont want to, in the end its you car, do what you feel you like best
in my experience most people who get 19's end up regretting it once they see another G w/ 20's and how it looks way better
just make sure you get quality wheels, such as work, DPE, iforge or HRE if like you said price doesnt really matter
or any 3-piece forged wheel would do

Very True.
