I can't expand that diagram, so I can't tell what you're supposed to do with it.
In a previous life I put 345mm S3 front brakes under a set of 17s. It was a tight fit.
I've also faced an issue where I ran Brembo four pots on a 312mm disc and had next to no wheel clearance - the aluminium expands when it gets really hot and expanded to the point where it caught the back of the spokes of the wheel. A temp wheel, but too late by then
