I saw the Options Remorse thread and thought we needed one for regrettable mods.
.2" coil-overs with weak springs (should have went straight for 2.5")
My issues came from a lack of knowledge concerning what I was getting into. I knew rock crawling but some of that hardware just isn't made to take high-speed abuse. I could have saved a few bucks on my build if I went straight for the hardware I currently have, but then I wouldn't have spare parts. It's a trade-off.
