Hey Matt,
I installed the H&R OE springs on my car a few months ago, they have a similar drop to the Eibach Pro. The H&R OE were a 0.75 inch drop, the Eibach Pro are a 0.80 inch drop.
I bought a camber kit for the rear thinking I would need it, but ended up not needing it at all. I installed the springs and noticed how minimal of a drop it was, just enough to make it look and handle a bit better. I took it to my local tire shop for an alignment prior to installing the camber arms and it was within recommended settings by a comfortable amount. So the moral of the story: camber kit is not necessarily needed with how minimal of a drop the Eibach Pro's provide, rear camber is able to be brought within stock camber numbers with ease.
Hope this helps, take care brother!
