guys. he weighed the sedan sx wheels not the koups sx wheels.
id say the koup sx wheels weigh just as much, the car isnt designed for racing its designed for looks kia doesnt care how much the stock wheel weigh.
and arine, aftermarket wheels vary in weight. it really depends on how much you want to spend.
From what I have read, 215/45/17 tires weigh 23lbs so that would mean the wheels only weigh about 22lbs which isn't that heavy. So even if you get the Volks @17lbs you are still @ 40lbs per tire and only saving 20lbs in unsprung weight. Not worth the extra $$$ IMO.
At 22lbs, that's not terrible. I don't think I'll ever swap my SX stock rims, they look way to good Plus, they allow a nice amount of air for the brakes.
