I did 23 in the front because when they are square, the front sticks out further than the back. With the slight stagger, it looks more symmetric. Purely cosmetic, and it doesn’t adversely affect anything. In this shot you can see the symmetry. It is a bit deceiving though as the wheels don’t poke at all, just looks that way in the photo.
Anyway, 12 pounds per corner with those forgelines is a huge weight savings.
