Sure - I think you'll find that the 30mm are still soft; that's what I've found on my car, and I run right at 2620lbs (min spec weight plus room for error). I suspect you'd be better off with at least 32mm. This, combined with your monster swaybars, might well be a decent starting point. Then it's matching up the shocks to the suspension; in my case accomplished by shipping them in and having them redone. But you're going go with the AD's? Is there any statement out there what range of suspension they can deal with/are valved for? I'd hate to buy a shock and find out after the fact that I'm out of the range of adjustment...
