Sorry if this has been discussed before, but I was unable to find anything when I searched. I have an 05 LS sedan. I use it to haul my tools (about 200-250#). With it loaded, there is a considerable drop in the rear. I added some rubber spring helpers, which temporarily raised it back up, but within a week they had settled and it was sagging again. I considered buying the Airlift 1000 kit for it but I feel the airbags would get damaged on some of the roads I travel on. The Maxx springs show to be slightly thicker, with a higher load rating. I have access to a Maxx at my local u-pull. My question then, is it worth it?
