realistically if ur after rims that just look good buy whatever u think looks good, unsprung weight will play a decent role in how the performs, but when it comes down to it if ur not someone that thrashes ur car u will barely notice it. saying that for $1500 some decent 2nd hand genuine rims can be had, but they wont usually be in the condition of the new wheel for obvious reasons.
ur usually better off buying Japanese as they are one of the few countries that has regulations and standards for wheels, Australia doesnt which means the cheapest and nastiest wheels can be sold. not to say these are, but u never know. these copies usually use a very cheap casting method which means to build strength in their wheels they need to use a lot more metal which = weight.
