I’m new to the forum and really only commenting to get my post count up.
Are you sure the swap is possible? Caliper mounts tend to be pretty standard and the hub moves its mounting point to accommodate the change in size. That way brembo, or whomever, can pump out millions of parts and sell it to dozens of brands.
That being said, nothing a waterjet/cnc cut set of brackets cant fix.
Just something to consider
2. Purchase adapter bracket, there is one vendor I know of in Russia that sells them.
3. Bore out the front rotor hub as it’s not hub centric to E-series cars.
4. Rears may be a direct swap as F series M5/6 just had single piston floating calipers so the caliper carrier bracket might have the same bolt hole width and it’s just taller to accept the bigger rotor. I would do the fronts only and paint to match the existing rear.
