The Apex fitment guide makes 305 sound like a tight squeeze, but I see other 305’s being successfully fitted in this thread and elsewhere.

FWIW, my M2 is lowered around 10mm in front and roughly 15mm (I’m guessing as it seems to have settled a bit in the rear since install- open to changing ride height) in the rear on Ohlins R&T. I’m also already running a fair bit of camber at 3.2f/2.4r.

Backup would be to try 265/40f and 275/40 rear, which might not be horrible from a handling perspective as I’m torn on square vs staggered. Will probably just require some massaging of the front liners.
I have the same wheel setup and suspension drop with the thought of running 275/305/35/18 NT01 as one of my track tire options. While I haven’t tried that specific setup, yet, my garage measurements tell me it will work.

I was measuring offset/tire size/clearance from the 19x10.5 ET45 305/30 RE-71R rear that I used to run to estimate if it would fit. The NT01 setup is about 1/4” taller and 1/4” more outboard, and it seemed that amount of room was available. It’ll be tight but should work.
