Which brake discs / pads for the Phaethon? Original or good alternative from the accessories

Hello together, have found only one post from 2012, would like to ask the question at the moment and hope for experience… Does someone have brake discs / brake pads installed which are not original? If yes, what experiences did you have with them? I drive a GP3, V6 TDI, 55 tkm and probably must change the pads soon.. Yesterday came a warning, brake pads control…. Looking forward to your feedback../Experiences Thank you and greeting Gerhard
