S4 B8 - 18" or 19" - Alloy Wheel options?

[FormativeYears]

I'm looking for suggestions for 18" and 19" alloy wheels (ideally OEM) for my S4 B8 (Black Avant), since my original 18" wheels have Winter Tyres fitted.

So far my search is consisting of:

- Rotors (5 spoke) - 8K0601025AR
- RS6 Tri-split 5 spoke - 8K0601025CM
- V-spoke - but do they come in less than 20"

I understand that I need to look for 8.5J / ET43 and a 66.6mm centre bore, but would any other slight variations also fit without needing to modify the arches?
