Need help with tire size decisions.

So here is the dilemma (and maybe I just can't visualize it properly).

Let's start with the front.

We have already established that the best offset for CV2's in the front is +32, and the best tire is 245/35.

From my spreadsheet the tire edge will be flush (or 1mm in) to the outside edge of the front fender. Lip of the rim wil be 9 mm inside.

I assume I want the rear to be very similar for an even look.

If I go with +25 (10.5) in the rear and 285/30 tire, the tire edge will be 3 mm inside the edge of the rear fender. Lip of the rim wil be 6 mm inside. So maybe a 3 mm spacer to even it out. But I will loose some of the concavity.

For greater concavity, if I go with +15 (10.5) in the rear and 285/30 tire, the tire edge will be 3mm outside the edge of the rear fender. Lip of the rim wil be 2 mm inside. So that would look uneven compared with the front.

If I go with +15 (10.5) in the rear and 275/30 tire, the tire edge will be 2 mm outside the edge of the rear fender. Would I even notice such a small difference?

Please comment on any of these set ups. I want to pull the trigger on this purchase pretty quick.

Thank you.
