I've used several pads now
Oem I'd chuck em straight in the bin, I've got a set here with less than 100 miles on them and they squealed........
Red stuff had chamfers and slots, were great but after a few thousand miles lost their bite and I was getting terrible judder/vibration from deposits on any longer journeys.....
Yellowstuff had them in for less than 2 days, as they started falling apart, not good.
Tried Brembo sport pads, marketed as an alternative non squeal pad, great for 3 weeks then squealed like the oem ones.
Only ones I've had any success with are the Ferodo DS performance (not the 2500) bought the FDS 1334 (Evo x fit, same Brembo Caliper) and these are the ones I'm going to stick with.
I'm currently waiting for the rears to arrive.
