I’m planning on replacing (pretty much) everything behind the wheels when I do my engine rebuild. I’ve accounted for the brakes (baer rotors and calipers), stainless lines (any recommendations), JIC coilovers, new CV boots and tie rod ends. Now, are there any other OEM suspension or braking parts I should replace while I have everything torn down? A link to a write up or an older post would be fine, I tried search but found way too many results to sort through for what i'm looking for specifically

I would think those Baer Upgrade kits would come with stainless lines, if not I'm sure you could get them from them too. Of course I'm sure you know to check out your wheel bearings and any other movable parts you haven't replaced lately.

prothane or energy suspension poly kit...it replaces the stock rubber bushings...but there a bitch to install

could get f/r lower tie bars

mine helped a lot

don't forget to inspect your inner tie rod ends, sway bar linkage and balljoints.
