Got a UK mk9 with 2.8 6AT with what I believe is 3.909 ratio diffs.
Wanted to know what options for a ratio change between 4.5:1 to 4.8:1?
Is there any factory ratios that will fit my vehicle?
I presume I only need to change the front and rear diff crown and pinions.
I will do all the work myself to swap them over.
