A few weeks back looking for rotors and pads for my 140 TSi Sport T-ROC I found thanks to Lucas_R 2 options for the front ceramic pads - P58147N (Acoustic Wear) and P85126N (Electronic Wear) ..... these wear indicators were the only difference noticed.

I'd hazard a guess that with the R that would be the difference also.

Can't get onto the brembo site to qualify
