Searched but can't find much on this.

As an NSX owner I am acutely aware of what lightweight wheels can do to performance, and am a firm believer in lighter (and stronger) is better

The RS6 I am looking at has the option of stock factory rims, or 19x10 Rotiform R121s. Has anyone weighed the stock rims, and compared them to the aftermarket options?

Or am I overthinking this given how much more the RS6 weighs vs a 3000lb NSX? I saw one owner with Volk LE37s which I have had on my NSX, and that is great choice BTW.

Thx in advance.
