I think the consensus here is that you should keep your stock wheels and save up for something actually worth purchasing. They are decent wheels, but for a $30k+ car, please don't. And plus, if you buy a replica, you're going to end up wishing you had saved a little more and gotten the real deal.
If you really want to go budget friendly, just have your OEM wheels refinished in a shade of gold you like. It's cheaper and looks good. That way you can still save up money for those SF Challenges you've been drooling over yet satisfying your craving for gold wheels.
On a side note, I'm pretty sure the Rota D2's listed above are more likely replicas of the SSR Professor SP1 than the Work Meister S1 3p.
