Brake pads DIXCEL or Tesla

Several teslas, both S and 3, and never had to replace them. I got used to one pedal driving. My 3 has almost 60k and brakes are almost new.

2014 MS P85D 102,000 miles still on factory pads and rotors.

I have about 50k miles on my 2018 M3. Pads still seem to have plenty of life left.

Stock calipers with Dixcel SD slotted rotors and Dixcel ES pads.

Dixcel ES pads are a “fast street” pad with low noise and dust that out perform oem pads and can be used for light track application also with effective heat range of 0-600 degrees Celsius. I think they’re the best “bang for buck” pad you can get.

What type of maintenance do they need? Can you get parts for them (say brake pads) easily?
