Adjustable strut rods - durability for street use

Not directly answering your question, but before you invest in adjustable strut rods, be honest with yourself about your front end shop's abilities- most have no clue how to adjust a Chrysler t-bar suspension to begin with, and once you throw adjustable strut rods into the mix, they're totally lost. You're throwing another step into a process that they already don't understand.
So, unless you do your own alignments or have total faith in your shop, you may not get the full benefit from your investment.
