I did a bit of intense research on this brake pads thing , and for what I finally concluded , you can replace and install sintered pads if you have replaced the rotor with an aftermarket one , like the Galfer rotors , for example .
The OEM rotors , as far as I understand it , will wear fast and produce noise with the sintered pads.
Ceramics pads , I have no idea .
The Galfer semi metalics are the equivalent of the OEM pads . They are easy on the rotors , have very good modulation and feel and will last a very long time .
Now , having said that , they also produce a bit of dust as all semi metalics do , but faced with the prospect of noise and faster wear on the rotors and having to get new ones (a very expensive proposition , I may add) against a bit of dust which I can perfectly clean up ... it was to me a no brainer .
I have already replaced the brake lines with SS braid Galfer brake lines , so the feel on the brakes has improved .
Fortunately for me , as I previously commented , I found out that my pads are still perfect and good for many miles , so I`ll store these new ones until the time I will need them.
This is my own personal opinion , of course , and I got to those conclusions entirely on my own . Anybody else is entitled to his own reasoning and may arrive to think differently on which pads will fit better .
