Ive done it on my 3i i cant tell you how well it works yet as i havnt driven the car yet
I got the brackets of a bloke on ebay but after looking at other peoples there all of a similar design.
sierra cossie 2wd calipers as i wanted the solid disc's & a mk5 rs2000 hand break cable.
This is how the bracket fits to the hub we had to nick a couple of the corners off the bolts so the hub cleared properly.

We bolted the disc on mounted the caliper to measure for the spacers to make sure it sat in the center over the disc made the spacer & bolted it all up

(the caliper should be mounted the oposite to the picture it was just put on for the picture)
I put all new brake lines on through my project so i dont know how you would go about doing them hope this helps.
