Just wondering if I'm going to noticed a significally amount of weight added to the GS when i put the rims on? I know they are going to be heavier than stock but Is my car car going to be a slug now with the rims? Loss of HP etc.....

With the wheels you are going to notice a ride difference because of the loss of sidewall, and a handling difference because of the added unsprung weight.
And the car is going to feel slower because it will be.Ha! But its not slower because of the weight, its slower because of the loss in gear ratio.

I noticed my car is slower now with 18s instead of 16s, and my gear ratio is the exact same as before.
you'll feel it, and if you go with a fat setup you will feel it even more.

I'll re phrase.Youll notice more of a difference from a taller wheel/tire combo more from the gear change than from the weight.

I got 19 fat setup, and a 50pound of heavy sub in the thruck, but the srt and hks offset the difference! well, feels faster than with 17' stock and no mods!!!

That rotating mass will hurt the performance, ride quality(without a properly tuned shock), so I try to stay as small/light as possible and still have the car perform the way I want, really don't care too much about pimpin'.

Driving in your GS4, i highly doubt you will notice any real difference. Your car will definitely not be a slug.

How big are you going? If you buy lightweight rims you won't notice anything. My 18" volks(17 or 18lbs.) are lighter then the stock 16"s i beleive.

yes with heavier wheels, that's spinning unsprung weight, so your car will definitely feel heavier.

if the weight is more towards the center that's better, but if it's towards the outside of the wheel, your car will get quite a bit slower
