Suspension for AWD drag racing Options

[KOU In3]

I've been meaning to post this for some time but keep forgetting. I've done a lot of searching on DSMtalk and others but have been finding mainly info on FWD or autocross set-ups.

What the consensus on the best suspension settings for drag racing. Obviously maximizing contact patch as far as camber, etc. But what about stiffness? As stiff as possible all the way around? Or some slack up front to minimize rebound after the initial backwards weight transfer shifts forwards again?

I know the general comment is, "it's awd, it doesn't matter." But I'm not so sure there isn't a healthy amount of time to be shaved off from proper suspension work. It seems to pay dividends with the FWD and RWD guys, why not us?

I've read in a few places that the AGX's are rebound/compression adjustable with the same knob/screw. Haven't actually heard this from KYB though, so I don't know how true it is. But even if the shocks are only compression adjustable, from what I understand, it still takes the shock longer to expand when a load is taken off of it, if the shock is set at full stiff compression. This is my reasoning why the left front wheel was coming off the ground at the full stiff setting and not at the fool loose setting in the front. But there are other factors to consider as well, such as maybe I didn't launch it quite as hard or maybe the angles of the sun and the moon caused the gravity in the vicinity of my rear end to preload the rear suspension making weight transfer an impossibility...maybe not.

A spool or locked diff definitely has its launching advantages and I'm still considering one for my set up, but I just don't know if I want to put all 4 CV joints through that kind of punishment around slow turns. Guess I'll wait til my weak 2-spider blows up to decide.
