2006/7 DCCD System - differential question

Hello,

Are all models of the 2006/2007 Impreza STI equipped with an electronic-controlled multiplate clutch (central differential) and a Torsen mechanical LSD (rear diff)?

I was just about to order a 2007 Impreza STI but i heard some rumors that some of the newly produced vehicles come with the older model differential specs.

Any opinions? How can one destinguish which differential types have been installed on the car?

Thanks!

Thanks for your reply!

Is there a difference between DCCD system and DCCD-A system?

The DCCD-A has a driver controlled centre differential with auto setting & replaces the viscous coupling diff (A manual on/off switch determines manual or automatic operation)

I appreciate your attention very much!

Do you happen to know how to destinguish if the car is DCCD-A or DCCD equipped? Maybe a letter or indicator on the dashboard?

On/off switch on the center console next to the handbrake.
