JCW R53 Mini brake upgrade. Larger 294mm  drilled and vented discs with R56 Cooper S calipers which have the larger matching carriers. This was the R53 Cooper S upgrade. Built from bare castings, with all new parts, seals, sliders, shims, bolts, nipples etc. Top quality and detailing and are as new.  Very original JCW look with top quality German discs, Mintex pads and flexi pipes. In my opinion the best brake package for not only stopping but for looks and authenticity!
