Diff upgrade options Mk9

[superclarkey]

Hey,

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.

There is more than just changing the gears you have to set the back lash and the contact points on the gears get it wrong and you will be doing it all over again

Appreciate the concern, but I will have no issues rebuilding them as long as I have the parts and they are comparable.

All I’m lacking is what parts to order.

Anyone know?
