Yep....

TBH, given how close that looks, you'd struggle with rolling to get good results.

If you can adjust the camber, running some negative may help, but also maybe not what you want to do.

Looking at the photo with brake disc removed, it does look like moving the wheel inwards would be a good option, or even if it was only a few mm..would mean less cutting of the arch itself.

But it looks like there's going to be some cutting one way or another.
