With the fiesta centre kit you will need to buy the calipers and a brake bais valve seprately.I have there kit and now i wish i hadnt bought it as i think i could have made it myself apart from the bracket's.If i remember right the rear hub you get in the kit is just a fiesta mk2 or 3 front hub that just goes onto the stub axle.I will get some pictures soon of mine as i am gonna be stripping them down.Might find out if someone will make sum brackets up using mine as a pattern.
