300mm front brake kit is a great mod for the puma, as is the lower strut brace, fit a full set of polybushes some slightly lowered suspension and you'll have a great handling car.

As for the rear brakes, the drums will be ample if youve got a 300mm kit up front but if you feel the need for more (like i did) then you can fit a range of rear disc conversion, Fiesta ST or anything of a 4 stud focus inc RS, even an old RS2000 will fit with the 2 pot calipers, but these are abit old and nakered now, best and easiest option is the Fiesta ST.

hope that helps
