just discs on the front on mine,mine was a bought kit using fiesta calipers,custom back plates,and as yet unknown discs,it all came with re con king pins and once id sorted the dodgy bits it fitted fine !!......i have'nt bothered with rear discs yet,the stopping power at the mo is fine,there are kits out there for 500's for rear discs,not sure if a handbrake option is there or not tho,maybe just for circuit use...
