17's look good?

Add to the fact larger diameter wheels are usually heavier and you are increasing the amount of work needed to spin the wheel...requiring more HP to overcome.
It's the equivalent of adding taller gearing, or stepping up to a taller (smaller sprocket on rear) gear on a bike.
Also, say you have two wheels of the exact same weight. One is a 17" wheel and one is a 20" wheel. Even with tires they are the same weight, but the 20" wheel will require more energy to spin because the area of most mass (the actual rim) is further away from the hub. The 17" wheels rim is closer, so mechanical advantage allows it to be easier to spin. it's why drag racers go with small diameter wheels. Less HP needed to spin them. You also get larger sidewalls which help absorb the shock of a launch resulting in less tire spin. Short sidewalls on low-pro tires don't flex as much, so it's easy to break them loose.
So larger wheels usually costs you speed.

Larger diameter will help with top speed but does hurt acceleration.

take a look at these.. they are pretty nice and not that much money and they are 19's. depending on how much you have to spend.. i just hope the tires wont cost that much.

Likely, any stock G (maybe even a Yugo) can take me on the quarter and can do 0-60 faster than my car... but I'll fly by you at the 1/2 mile since when my speedometer says 90mph, I'll actually be going about 93mph while yours will be going 90mph (these are examples only-- in the real world I don't pass 75).

ok but would these rims look good in 18"? Or im i wasting my time and should go with 19"...i really dont want to spend all the money on 19 cuz i know there expensive. I would spend it on 18 but yall said that 17's would look too small cuz of the way the rim looks, what about 18? or should i just find a different rim?....
Thanks

Yes i did find some 19" coupe rims for cheap, I know they will fit on my 06 sedan but I did read in the sticky forums that each wheel has a special sensor on it.. Do I need to worry about anything like that even though they are already infiniti rims?

They are a universal sensor not specific to infiniti's. In fact, i beleive every vehicle after 2008 or 2009 is required to use them.
So if you buy the coupe wheels, they will have the tire pressure sensors. You will need to go to a dealer and have the sensors reset and programmed to the vehicle. Any time you swap the wheels around, you'll need to do this
i think that a 17x10" rim with a 20 or so offset with the appropriate drop would look just fine.
now if you just slapped on some narrow, stock offset 17's with no drop, that would be a waste of money
