Front BBK

[Memphys™]

Hy guys, i found in the web the next set of BBKs in the front, and Im wondering if somebody used it and what kind part do i need for it (brake disk sizes, brake caliper types...), whats the minimum size of spacers (if i need them)
300mm brake disks and Porsche brake calipers:


I know its available on 300mm.de but i wanna try do it myself
