You're right the wheels do look awesome.. However i think it is those red calipers that set them off. Would the dealer do that or is that a special order?
I've looked in to this some few months ago. It's a sport and sound package...however only offered in Ireland and around Europe...just not here

I am having this done for me at a cost of 45 a corner, not cheap so shelling out 180 for all 4. However if you are gifted you can do this yourself. Think a lad on here has done a damn good DIY job (want to say norbek I think is his username).
