Sirion rally 4 / 4trak / awd info


Hi guys, new to the forum, just looking for some info regarding the 1.3 sirion awd. I believe its called the rally 4 or 4trak in the UK, and in Germany its just called the awd sport.

1st what type of awd system do they use? Is it a centre differential or a viscous coupling?

2nd what is available in regards to front and rear LSD? (Also any information on the rear diff would be greatly appreciated eg. manufacturer, part number ect)

3rd do they run the same transmission as the storia x4? (I am aware the ratio's are different, but unsure about the housings)

I have been scouring the internet with very little luck. Hopefully someone here can give me some good information.
