2. The front BRZ control arms for 22+ models are a different part number than the old arms for steel uprights. Not sure what the difference is...bushings are the same. It might be a fitment/geometry thing with the new aluminum uprights. Perhaps @ Opie knows since he had a set. Might be nothing important.
I've been thinking about doing something like this with my 1st gen but we've been busy!

This is a very informative page. Shows the ins and outs of a 2022 BRZ knuckle swap into a last gen (and i assume applies to the 2022 GR86 wholesale also).

You would need to run Google Translate etc. Says some bolts need to change due to longer lengths needed for the alu knuckle. But also an interesting problem about the outboard ball joint (not possible to buy separately) of the FLCA being not long enough. Maybe thats the reason for the diff part number rather than any geometry changes?
Wonder if an (even lighter....) aftermarket FLCA (cusco, SPL, racerX) can fit the alu knuckles instead. Since the stock FLCA cannot plug and play per se. What the writer did was get a toyota castle nut which is thinner where it counts to allow the pin to successfully engage still.
