Yeah thanks for the ideas. Not bashing dropzone at all but just trying to figure it out. I plan to use them again. I know they went because i heard the pressure release in a sudden pssshh as i lifted the rear of the integra higher up. I had it kind of heigh so i could get under it with no probs. Nothing else would make that sound. Tomorrow im taking back to the store and im gonna see if they wont give me new ones and send the busted ones back as manufacturing defects.
