you really cant go wrong with the st170 discs and mondeo calipers on the pums, such a great cheap upgrade,
ive got the fitted to my track puma and with 180kg less than the standard puma there brilliant.
only had fade once on track on my 8th session of the day and they were the same set of pads which were on their 4th day so ill let them off lol.
obviously with braided lines you will get an even better pedal feel and ive got racing 5.1 fluid as well but for everyday driving and if you want to give it a good caining every now and then they work brilliantly.
i have the earlier servo as well, pre2000 which apparently gives a better pedal feel too.
heres a couple of pics.
