With the two piece rotors, you don’t have to replace the whole thing. Replacing just the rings is an easy and cost effective way to go. Couple of after market suppliers out there. I went with new DBA rings and they work great. I also tried the Z25 pads and not thrilled with them (less stopping power). Went with Stoptech “street” pads and super happy. All the OE Brembo pad bite with less dust.
