Reducing gas pressure would help but may affect performance. Do you know what your adjuster controls (i.e. bleed or preload)? Got a shock dyno?
As for your ride height, why not use helpers? I basically always recommend them, and they're even more useful with springs as stiff as yours if you want to get the ride height right.

Thanks for your reply Andrew!
The coilovers are MCS 1-ways; I found them used in the member classifieds here for a great deal. The adjustment instructions say that they're "adjustable in rebound and the compression forces will adjust in proportion while adjusting rebound." I don't think I've ever seen a dyno for any MCS shock.
I tried increasing the rebound in front, but it didn't seem to eliminate the occasional bobbing. I think it made the oscillations smaller in amplitude and maybe less frequent, but they were still there.
I did order some helpers and divider spacers to be able to lower the front a bit more, along with spring isolators for all 4 corners. The rear springs are 7 inches long and have plenty of room to lower before they'd not remain captive at full droop.
I thought the bobbing might be because of some binding at the caster pivot point on the front LCA. But if this is common behavior in these kinds of shocks, I'm not too concerned about it. It doesn't happen that often, although it's sometimes funny when it occurs at night. I kind of feel like an LA lowrider, when I see my headlights bobbing up and down off the car in front.
Thanks!
