2013 Sline Alloy Wheels Upgrade Advice

[BITDI]

Hi All.

 

Ive recently bought a 2013 Sline A6 and i'm looking to upgrade to 20" alloys. It currently has the 19" Lemans fitted to it and i think they come up small.

What Audi original wheels in 20" sizes do you have and can i see some pics for inspiration. Considering just getting a set of Black edition alloys but wouldnt mind something a bit different.

 

Also whats the largest you can go up to regarding offset etc?

 

Looking forward to your help. Cheers.
