Well if you do the front with 8112s why not do the rear? Nobody should have to ride with stock suspension when these are available.
I bought these to pair with a set of 8112's one the front of my 2020 4Runner. I have always wondered how much better external bypass are compared to smoothie reservoir shocks like my Fox 2.5 DSC's, it is noticeable. After emailing Ian a few times, I pulled the trigger on a set. I have daily driven on them for about a month with a couple of four wheeling trips, I did just over a 100 mile trip on twin track and some dirt roads in southern Nevada last weekend. I am EXTREMELY happy with them. Ian even "pre-set" the clickers after asking about my rear set up(what a swell guy, haha). Bilstein has proper sized metal reservoir mount/clamps, not a bent piece of steel and some hose clamps. If you are on the fence, you will not be disappointed.
