I have AP calipers on my newly purchased 2004 JCW and from work done by previous owner it seems to be shod with JCW pads.
Problem is i find these to be NOT upto the job of spirited driving as i suffered brake fade after 2 roundabouts and the discs had turned blue with the heat .
Not sure what size the disc is but maybe someone on here knows what size the AP caliper accomodates .
Would love to go for a 2 piece ally bell and rotor setup if any one does one for this caliper and what good fast road /race pad fits .
