Yeah, are there versions of the 6 speed that use different differentials?
1. Do some 6 speeds come with 3.9, 4.111, or 4.444 front differentials?
2. Do some 6 speeds come with 1:1 or 1:1.1 ratios that allow the rear differential to be that same as or different than the front?

As mwizard asked previously, how much did this bad boy set you back Alex? That is if you don't mind sharing, of course. (If you don't tell, I'll have to find out from Andy 
)

I will discuss the costs in the upcoming articles. 
No, AFAIK, all 6MT's have 3.9 rear ends and 1:1 rear/front.
There is STi option part, that can change the 3.9 to 4.444. That will be too short if you ask me, but super cool for auto-x.

FOr those of you with questions on the DCCD here is what I have learned, first there is a different tranny case (or at least one half is different) you will need the control wheel, loom, ecu, and micro switch (for the handbrake). FOr the rally team they usually run a rear bias only locking the diff when they break a drive shaft in order to get more power to the front. THe center diff operates on resistor variance. Other than that you already know everything hope this helps a little.

Just some extra info on this set up - - I have run the stock 6 spd clutch and tranny now - VERY abusively - including at least 30 full out drag runs - with between 450 - 500 wheel HP on NOS and the whole set up is stil in one piece and runs as my daily driver - - on launch like that with the 5 spd would have melted a stock clutch
also - the suretrack diff is GREAT in the snow - like a jeep
over all the 6 spd id worth every penny
But the gears are NOT ideal for drag racing - and - You'll feel the extra 85 lbs - - (not to mention the extra weight in the rear diff and half shafts)!
