wheels are a part of a car's unsprung mass. Unsprung mass amplifies the effect of a small amount of weight because the centriprital forces of rotation make the rotating mass of wheels and tyres and such much more hence making the car more sluggish. Im not very technical with this stuff and i could very well be a bit off with what im saying, but the gist of the story is that if mass rotates, it can make even the lightest weight alot heavier, hence if you have lighter rotating mass, the amplification is less.
Anyways, with the rims, maybe if you had your car lowered it would look better, but not when youve got a stock suspension setup i dont think it will look as good. If you aren't planning on lowering your car anytime soon, then go for a higher spoke number to give your rims a more fuller look, the lesser amount of spokes and your car will have a lot of negative space around the wheels kinda making it look its underwheeled
. (This is just my opinion from what ive noticed on other cars, please do what you want, my word aint the law).
I personally do like 5 spokes, but if the spokes were thinner only then. I think the second set of rims youre looking at would look really good, I personally am gunning for E46 M3 style rims, i think they are the best looking rims, but i cant afford anything such at the moment LOL.
Rims are such a personal thing so take good time and consideration before deciding what you wanna slap on there! And take good care of em~!!
