i got the fiesta center rear set up, havent fitted it yet, i have got a bias valve but im gunna fit 1 to each line to stay in with the normal system.
as for calipers, there just seirra/granda rear calipers, £5-10 each from scrappy.
the hubs are not mk2 or 3 fiesta front ones, as the front hubs have the lug's to mount the calipers on.

i do know what are used but im keeping that close to my cheast for now as i plan to make up some kits to sell

just waiting to get my lathe so i can make the spacers for the hand brake cable.
