Audi A6 2005 - downgrading to 16" wheels

[Vaud]

I have an A6 3.0tdi and want to downgrade the wheels from 17" to 16".

Rim 7x16 ET45 / Bolt 5x112

Is this correct? Any specs I am missing?

Can anyone recommend a good reliable source of Audi wheels (I don't mind used refurbished)...

Many thanks

Yes, those specs are ok but you also need to consider 57.1 centre bore as lots of wheels built for newer models will be 66.6.
Also you may find the brake calipers on the front are to big for 16's but im not 100% on that...

I went from 17s down to 16s (steel wheels on winter tyres). Had no issue with clearing the discs/calipers. Mine is a 05 A3 though.
