You're still backwards on a couple of points.

First off, if you have caliper clearance issues, you need to run a LOWER offset, not a higher one, pushing the wheel further out (and the caliper further out of the barrel) to gain clearance.

Secondly, I don't think you can call the rear brakes on a 35 small, at all.

The fronts disks are 348mm, and the rears are a surprisingly big 336mm. With equally beefy calipers. The rears are bigger than an N20s front brakes. This is mainly due to the "ediff" and the need for heat capacity back there.

Moreover, because they use sliders, they sit much higher off the caliper radially than, say, a Brembo setup would.
I agree, maybe I explained it wrong. When it comes to 3 piece rims, back spacing on the face can be pretty small/thin in the rear. My fronts are 2.25" thick and 0.5" in the rear. We have a 5.5" lip in the rear which makes my rear offset et20. My concern with those rims are the rear offset.
