My VT has super low suspension and when I'm the only one in the car everything is fine and I'm able to clear 99% of speed humps etc. The problem is when I have a full car load it scrapes almost everywhere. Now I don't want to raise the car, well not permanently with springs anyway so I have been thinking about getting either polyair springs or air shocks so I can have adjustable rear suspension. My questions are has anyone had any experiences with polyair springs? Their website states that they are able to return the car to stock height under heavy loads, but how well would they work in a lowered car? My other option would be to use air shocks but not sure how well they would work in a lowered car as well?
