What is the advantage of DCCD?
Seems to me that DCCD is a highly touted feature of the STi. However, due to my personal lack of understanding of drivetrains, I'm not certain I understand why it is advantageous to have a driver controlled center diff. I mean, I can see the advantage of having a center diff to split torque between the front and back wheels. Does the DCCD merely allow you to set the default torque bias or does it actually lock the torque distribution?? Can anyone explain this to me?
From what I've heard you'll be able to shift power from the front wheels to the rear wheels.. up to 65% to the rear (as opposed to always being 50/50). in a turn this would give you more steering power by putting more weight on the front tires. I think on automatic setting this would happen whenever your front wheels loose traction.. but in manual mode you could lock down some power for the back and possibly get faster starts

(My first two posts in that thread is what I am pointing to.)
The DCCD is what put the STi in such high consideration for me. It is, in theory, something that would negate the built-in tendency toward understeer in front-engined AWD cars, much like ATTESSA-Pro.
But I too am very surprised by the recent reviews in comparison to our watered-down US Evo. I'll wait and see what people are able to get out of both cars in SCCA Solo 2.
