What are the main differences between the pre facelift and facelift vRS models? Specifically in Australia.

 

is it equivalent to the MK7 to MK7.5 GTI updates?

 

I’m specifically looking for a model with the front diff (as per the GTI performance pack models).

245 HP all should have it, 230 not. 
 

pre FL 230 HP should have it, but they also feature black exhaust, black rear spoiler, black piano interior and stitched vRS logo behind head on front seats. This car was in its time something special and not that common. They also had only 4 colours.
