Would it help my launch if I put the acd on gravel or snow setting aka full lockup?

 

no, tarmac is the best setting for launching as it puts the most torque to the rear wheels

 

Tarmac ... ACD is dynamic ...

 

you know, i was thinking maybe launch @ Snow( 20% rear), then as soon as you get to about 60 ft, hit the button and switch to tarmac. theory was that it would launch like a fwd car w/ a little mored wheelspin, and maybe be a little easier on the clutch. haven't had time to test that theory though.
