Got these on my track MK5 RS2000 mate, also tried the 300mm set-up waste of time, i had to....

1. 5mm spacer between disc and hub to clear balljoint

2. Bracket off ebay (oldphonebloke is seller)

3. 5mm spacers between the hub and bracket and caliper and bracket

4. Get hoses made

5. Remove notch from caliper to clear the upper brake carrier mount
