RE: one giant VW buggy
That must be impressive to actually run that thing around. The rollover shouldn't be coming from that extra 15mm of height over width. Probably just the height of the heavy stuff, engine, gas tank, etc. Have you thought about moving the tank lower in the frame that would probably help some depending on how much fuel it can hold. But I don't now if the carb can suck up fuel or if it is a gravity feed. Maybe letting the chassis sit a little lower but then the body mounts would need changed. I couldn't tell in the vid if the suspension was actually flexing but it sounds like you have made some changes since the vid. That body looks awesome wish I had that kind of patience.
