I wonder if the metal heim type links have a note-worthy advantage in performance vs the poly... poly could self-destruct? I know... the heim type are not advisable for the "street", but which lasts longer??? I'mn at a point in re-assembling my car now to make that final decision (have FF adjustables w/poly bshgs waiting for installation).
I'd only be looking at ~2000 miles max per year.
Im pretty confident a std variety heim will not last longer. I can not really get a good look at the movement inside the K-frame there. And it seems loaded when jacked up. But I can see and feel that my heim UCA and heim tie rods are worn out.
I probably had 50K miles on my poly strut rods when I took them out. Still good.
