Run like 3 end to end, 1 with fairly big pressure(compared to the other 2) one a little softer then one plenty soft. Would act like a variable rate spring setup. I know that a single airbag won't have a large amount of droop due to the fact you can only stretch so far but 3 bags would be 3 times as much. Anyone know about the system I posted a picture of above? I realize its a comp thing and probably wouldn't be good for a full size but all this lightweight stuff has me thinking more and more I'm gonna try and pickup an S10 real cheap and start building a really light truggy.
