I WANNA DO A REAR DISC CONVERSION ON MY MK7 GTI BUT AM PUT OFF BY THE SILLY PRICES TUNING COMPANIES CHARGE FOR THE CONVERSION KITS. IS THERE ANY WAY I CAN GET A SET OF DISC & CALIPERS ON THERE FROM A MK5 RS2K OR ANY OTHER FORD? WHAT BRACKETS MOUNTING BELLS ETC DO I NEED AND WHERE CAN I SOURCE THEM??

ANY HELP WOULD BE GRATEFULLY RECEIVED!!
