Fixed Rear Bias?
Is there a system out there yet for going to a 90/10 to 70/30 rear-bias setup?
My center clutch pack is nearly done, and I'm considering the manual swap anyways, so what are my options? I want a mostly rear bias, and not having the system shift bias around is better, but some limited bias shifting is OK, as long as it remains heavily rear biased at all times. Thanks!

Manual swap would give you the best "driving experience"... Hoewver, if you want to stay "automatic" then source a JDM auto tranny (tranny, rear diff and TCU) from either Japan or Australia or Europe... I hear those SVXi are fun to drive

Just to follow up on Chris' post... the JDM SVX 4eat is 36f/64r biased. All the manual trannys are 50:50 biased, except for the STi DCCD trannys. The DCCD manual trannys have an adjustable f/r bias.

DCCD = driver controlled center diff
The f/r bias can be adjusted from 50f/50r to 36f/64r. There is a control module that goes with the tranny. DCCD trannys and control modules are notariously expensive. JDM STi DCCD 5MTs + control modules are probably around $3000-$4000, and the 6MT DCCD 6MTs + control modules usually go for $6000-$7000.

So a JDM SVX 4EAT would give me the same bias as the maximum on the manual DCCD? Hmm...interesting. I can't decide if I want manual or not. The other car(s) will mostly be manual, so it would be nice to have one auto around...

It is only on the dirt, when the wheels are having traction problems that tightening the LSC will change the torque split. As both sides of the clutch are running at different speeds, like the wheels. Harvey.

Hi Harvey. Yes, you are right, in manual mode, the DCCD will cause some binding issues during cornering if the clutch is set to full tight. In auto-mode, the DCCD module will vary the clutch action according to several sensor inputs (g-forces, wheel slip, throttle position, and probably more). If those sensors could be enabled, then it would be a more useful device for the street.
