I have a quick question regarding how far you can bend an a Firestone "small" airbag before you run into problems. I have mine mounted on my trailing arms in front of the axle. At full drop they are perfectly aligned and the top and bottom are parellel to each other. But as I raise the car up, the top and bottom of the bag come out of parallel. (one side expands farther than the other due the angles of the trailing arms in relation to the frame.) How much bend is too much for an air bag?
