Mine is fully open for everything!
having said that when I'm on track in the wet I'm not looking to set as fast a time as poss, unlike Duncan, so for me fully open is rather enjoyable!

SineSTI if its your first time out on track if its available I would take an instructor out with you costs about £20 but well worth it you will learn more in 20 mins with the instructor than driving all day without as for dccd I would leave it in auto for the first couple off sessions until you get used to the car at race speeds then if you feel more confident then switch it into manual and have a play.

I would say 1 up from fully open (i.e. first green notch you come to) until you are confident enough to open fully. I only use auto in the wet on the road and use the first green arrow I mentioned in the dry. Feels more planted IMHO.
I haven't tracked it myself yet though tbh. Let me know how it goes.

In my experience lap times are significantly improved with the diff fully open, certainly in the dry.In the wet, drifts do need greater finess to control in this mode so auto may be the setting you'd feel more comfortable if you're into drifting, if your a smooth and tidy wet driver, lapping with the diff open is still quickest.
Dynamix, in the 'wet'
warmup Oulton session I was running in auto, as the standing water cleared I ran open. Somewhere like Bedford Autodrome I am far quicker in the wet leaving in auto and drifting although there's no need for large cojones as the circuit is far more open only having one section of armco

What is this 'auto' option you speak of? 
Then again I don't even have ABS

Track day done! It was perfect fun for me. To be honest, I was driving in "Auto" mode all the time on the track. I feel "safe" like this. Well, it was my first time. Next time, I'm going to experiment. Car is perfect, tires are amazing on track (RE070) for my driving, off course. Nice day!

Great to see you had a good track day.
With AWD, I don't think we ask too much of the DCCD unless we completely lose it and keep the right foot planted.
The tip to pay £20 for instruction is a good call as well.
There is a Silverstone trackday on the SIDC site that may interest you.
Bit of a drive for you though!

dccd
hi there new to all this i have recently bought an 06 STI with PPP and think its awsome, i dont understand the dccd settings what do the settings mean as in front - rear wheel drive , if the diff is open is that when the wheel moves the indicator all the way down to the bottom of the dash display meaning that it is more rear wheel drive.cheers steve.

The centre diff is an 'adjustable' LSD, all the way back is a fully open diff, with rear torque bias (45:55), further forward is more and more locking, so as the rear starts to be affected by its extra torque the LSD increases the torque to the front.
To the rear does not statically incraese the torque to the rear, nor to the front increase it statically to the front, it just stiffens or loosens the LSD, in auto mode it adjusts it according to what it thinks is needed at any given time!

Well DCCD settings are subjective and you have to adjust it to your driving Preferience, style and ability. Although everone knows this, the Classic DCCD and newage DCCD's are not quite the same.
For me I found this works for me on my newage Type20 or to perhaps better to say I'm just happier with my cars handling. But I crash all the time
so don't listen to me.
On the majority of times in the wet I use A-DCCD. Braking is normally improved and use a slower in faster out. In the dry and damp A-DCCD and either fully open one or two up depending on best braking & stability.
On tight short circuits (Kurb or Elvington) A-DCCD worked best overall. DCCD manual DCCD seemed to gain on some corners but lose out on others.
Medium circiuts like Castle combe & Bedford very little difference in times if on Manual or Auto, although in Traffic found A-DCCD better for out of corner overtaking.
Long circuits like Silverstone, Donington and Nurburgring Manual fully open to first orange in the wet, very wet and braking issues back to A-DCCD.
I have been out with one driver of a classic who have adjusted DCCD on the "Fly" around the the Adverse handling circuit at Prodrive, I'd only be alright if I had 3 hands
To be honest I find "playing" Tyre pressures rewarded me more than "playing" with DCCD so not to bothered if forgot to alter it. Example my first outing on on RE070's at Donny, Standard 34f/32r tyre pressures, after Three laps were approx(memory!!) nsf 55 osf 47 nsr 42 osr 39 and handled like on crossply tyre
IIRC IMHO
