those are nice, if i was goin all out performance id get 15x6.5 Konig Heliums, they weigh 13ish lbs also, $110 a piece...but the 17x7 Heliums only weigh 16lbs....

but instead my girlfriend is buying me Motegi MR3's in 17x7 gunmetal..that weigh 24lbs so header/downpipe and buschur cat-back is my next mod instead of tint/bodykit haha

 

if i were going for light weight i'd probly go with with SSR... hot stuff and LIGHT, you can get 17.7.5 and 17x8 weighing in at a minimum of 13lbs and a max of 16-17
