I recently had your Evolution Z23 ceramic brake pads installed on the front of my 2015 Audi S4 and LOVE them. (My OEM brake pads were squealing before the changeover and the squealing has stopped entirely. Also, the brake dust has been totally eliminated!) In fact, just over the weekend, I ordered these same pads from RockAuto for the rear of my S4, the front of our 2012 Audi A6 and the rear of my son’s 2016 Audi S3.
