Tyrepower blacktown, bloke said ('off the top of his head') $260 per rim. Just a touch over a grand for the wheels, which isn't too bad, but then you have to factor in tyres and such, so you could be looking at anywhere from ~$1,500 to over 2 grand depending in what you wrap them in.
They're a new wheel from a seemingly reputable / experienced manufacturer though, I guess you get what you pay for (when compared to your 1-grand common chrome cheapie deals from Tempe).
Maybe somewhere else does em cheaper though.
Dumb edit: This is in relation to the Shift R's
