C diff ratios

[Spritely]

Hi all. I have a 2016 C220d 6 speed manual with 20”wheels. I am trying to find what the factory diff ratio is and what other diffs ratios are available?
It also raises the question as to what if any, other diff units (complete) are a straight swap?
As my advice appreciated.

You CAN change the Diff Ratio! On my W204 at Least.

Why?

Big wheels fitted by previous owner. Look great but make car slightly higher geared which is not great on country roads where I live. Just looking to see if this would be a relatively easy option. (The big wheels look great and it is difficult to revert on the basis of looks alone).
