I just consulted the Isuzu 1997 Phantom Drawing of the VX and it indeed shows the spring helper in very close proximity to the rear axel, definitely not in a stop wheel bounce position (If I knew how to scan I'd post it , I'll have my wife help me do it later,though). Also, if you consult the parts book on the front suspension page the rubbber bits are specifically called "bumpers", not "spring helpers" so we can't just blame translation issues here. We have a deliberately new piece of suspension nomenclature being offered. I continue to think this is just an inexpensive way to insulate and prevent roll. It's not the kind of thing you would trumpet the auto press though because it's so darn simple and basic looking. It's just plain clever.
