The EC-7 18x10" ET 33 would be the better choice for a square fitment. Perfect fitment in the rear, and spacers up front for proper strut clearance. Spacer thickness up front would depend on suspension type, and tire size/brand, but many have used either 10mm or 12mm.
If you used the 18x10 ET43, the rears would would sit a few mm recessed in comparison to the OEM rear wheels, but more importantly the front would require very thick spacers for strut clearance - 20mm or so.
Here is a photo of an AlekShop built M2 with our 18" EC-7's:
APEX EC-7 18x10" ET33
275/35-18 Bridgestone RE-71R Tires
Ohlins Coilovers
12mm spacers up front (for strut clearance)
AP Racing BBK
Now if you are strictly asking about rear inner clearance because you are only using them in the rear, either the 18x10" ET33 or ET43 would work just fine. Keep in mind the proposed FL-5 rear wheel in the OP is 18x10.5" ET40, which sits 3mm closer to the rear suspension than the 18x10" ET43.
We're initially running with the FL-5 design due to popular demand, and depending on how these sizes sell we'll know if a second design is warranted or not. To be determined.

Did Alekshop's M2 have rear AP Racing BBK as well? I'm planning on upgrading to APR BBK all around and would like to run a staggered setup. What would be the ideal wheel setup to run 275-305? Also how much minimum camber would I need in the front?
