Pic of Center Console on STI
Here is a Pic of the Center Console on the STI from the Detroit Auto Show. It shows the Center Diff Control. I know others were asking about the console. The pic is not the greatest but if you want the whole pic just leave a message here and I will email it to you.

There are some great pictures of the new North American STi in i-Club's Gallery section! But I didn't see any STi pillow ball camber plates. I wonder how many other little details will be omitted as a cost reduction?

DCCD stands for Driver-Controlled Center Differential.
It allows the driver to manually bias the torque split between the front and rear wheels on the fly. At the maximum setting, it allows the driver to make the car behave more like a locked AWD without slippage between front and rear. This is helpful in loose traction conditions because it limits wheel slippage between front and rear, thereby ensuring power isn't wasted spinning slipping wheels. Rather, all wheels spin at the same speed as power is distributed evenly between the wheels with and without traction.
At the other end of the dial setting, the the front and rear wheels are de-coupled from each other, producing more of an oversteer characteristic similar to a rear-wheel drive (RWD) car. Max torque split is 36 front / 64 rear.
It would appear the DCCD system uses speed difference between the front and rear wheels to actively determine torque bias when the dial is set somewhere in between the two extremes. This criteria is different from popular Torsen differentials which SENse TORque to bias power between front and rear wheels.
An added bonus is the e-brake disengagement! No more locking both rear and front wheels during e-brake maneuvers! E-brakes are totally useless in the current WRX because the front wheels lock-up when the rear wheels lock. THis forces an understeer, presumably during some amateur's attempt at a WRC style powerslide. Bye bye shiney new car.
Here's a much better and longer description of what it does. Excellent work by these fine gentlemen.

At the center top of any i-club page . . . click the button that says "Gallery" and then the "North American 2004 STi".
or you can go here.
