hehe i have the same pads and had some bad squealing at first.
Did 6x 110-70km/h hard stops on the freeway and then a 30minute cooldown drive without touching the brakes.
This reduced the squealing by a lot but still squealed.
Took car to Traction Tyres and they added some anti-squeal, lightly sanded the rotors. This got rid of the sound for a couple of days, but usually comes back when doing very light braking.
Let us know if you fix the remaining squeal
P.S; from what ive been told, the rotors should be machined when putitng in the new pads, as my rotors were brand new I did not need to machine them
