Suspension novice here!
I have modified my '07 Vibe to have a rear swing gate containing roughly 300lb in jerry cans, tools, and the steel construction. The rear end of the Vibe seems to be sagging a bit (maybe a lot). I am looking to lift the rear end while staying mechanically sound and on as small a budget as possible. I've looked into airbags or adjustable coil-overs but I'm not sure which way to go. Any suggestions are greatly appreciated.
Sincerely,
