stock lca's angle.
 

Do stock lca's angle downward a little where they connect to the chassis. My rod end bmrs definitely angle downward although they are set to 19.25 in. (the same length that I measured fro stock.

Can someone please look at their stock lca and tell me if they are parallel with the groung or if the angle down toward the connection on the chassis?

stock they are paralle. you want it to be. when i lowered my car they werent anymore and it rode like shit and had no traction until i got relocation brackets

is your car lowered or stock spings? if there stock springs then they must be sagging

The car is at stock height with stock wheels. Would a lagging stock spring make the carrier tilt, and thus produce the angled lca? Shouldn't I be able to adjust this out with my adjustable lca's?

Maybe a pic is in order.

My rear springs were worn out and the control arms was angled upward...you want the Lca's to angle down. So I suggest grabbing a set of new springs and/or relocation brackets.
