This is probably a silly question, but does my 02wrx have 3 differentials (front/centre/rear) or just front and rear and are all there mechanical diffs or does the ecu switch power from say front to rear and left to right - how does this setup work on a scooby?

 

bump

 

I think you will find that the car has an open diff up front, a viscouse diff in the rear (lsd) and a fixed position viscouse diff in the middle.
There will be no electronic intervention to the transmission.

This is based on what I've read, not personal experience.

 

dont think 02 wrx has rear lsd
