this is what i learned from many technicians.

weight of wheels just reduces weight over all of the vehicle.

added weight with wheels does in fact effect handling, but it is something we can't really feel.

its like a golf club, even though your shaft of the driver is heavier, you can't really feel the added weight because its in your hands, what you can feel is more MOI (moment of inertia)

the guys here feeling delay when turning or switching lanes, it is because of your sidewalls on your tires.

now it can be that the sidewalls are weaker then the stocks or it can be that the PSI is to low.

Q_350Z_USAF i hope you got the hub rings, you really need them, and i am 100% sure this will solve your problems, if you call axis and ask them the bore size for the milano wheels and the stock bore for the Z, you just give an autozone guy those numbers and that you need a hub centric ring for these measurements.

put them on and your vibrations or rough ride will be gone.

but someone else mentioned that with 19's your ride is going to be rougher, this is totally true.

you have thinner tires, the contact of wheels and ground are closer.

thanks to everyone for all the great input... when i read the first few posts i was kinda scared (cause im about to go from stock 17's to adrmsport 19's with falken's in the front & back 245's and 275's)...

jmaldanado... can u please pm me the specs on your tires thanks!
