I sound like a noob but in what position should I set the DCCD to get a 50/50 slpit of torque and traction?

Default High Octane and DCCD

Just a little bit before the LOCK position, not EXACTLY 50/50 but close to it.

Can't be done, DCCD does not change torque distribution.

If you want no slip between front and back wheels, which is probably what you're looking for, just set it to full lock.

Funny to see how some people, without having an STi, comment just based on hearsay ... :roll:

ok so from reading this article im not sure WHEN to use open or lock...this only describes how it works. Im assuming you leave it auto for normal driving conditions and lock it under limited traction condidtions? lemme know if im wrong, im a bit confused.

Yea, pretty much.

I'm not sure what's best for the track, but basically leave it open/auto most of the time, and when it gets slippery, turn up the lock.

Full lock should be saved for gravel, dirt, or snow.... it's not good for rain, you still have too much traction. (based on my experiences w/ a 4x4 truck....)

I only mess with it now if I'm trying to get maximum acceleration on a slick surface. The rest of the time I leave it in auto, and that seems to work very well for autocross as well.

I think most of the confusion surrounding the F/R torque split stems from the fact that people don't realize that the DCCD clutch distributes torque in proportion to slip - just like a common LSD. Otherwise, the F/R split is simply a funtion of the DCCD's gearing (35/65). At least that's my understanding.

Yea, that's a pretty good way to explain it.
